The possible regulatory role of miR-514 and miR-642b in cumulus cells on the oocyte maturation in patients with polycystic ovary syndrome. Reprod Biol 2024; 24:100863. [PMID: 38367330 DOI: 10.1016/j.repbio.2024.100863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 02/06/2024] [Accepted: 02/07/2024] [Indexed: 02/19/2024]
Abstract
Polycystic ovary syndrome is a common endocrine disorder in reproductive-age women. Accordingly, abnormal microenvironment may negatively influence oocyte developmental competence as a result of the altered expression profile of cumulus cells (CCs), mainly the key players of oocyte maturation, such as epidermal growth factor receptor (EGFR) and prostaglandin E receptor-2 (PTGER2). This study aimed to examine the expression levels of miR-514, miR-642b, and their candidate target genes (EGFR and PTGER2, respectively) in CCs of immature and mature oocytes in patients with PCOS. A total of 40 oocytes at germinal vesicle (GV) and 40 oocytes at metaphase II (MII) stages were retrieved from 30 PCOS women. Quantitative real-time PCR was performed to analyze the expression level of miR-514, miR-642b, EGFR, and PTGER2 in cumulus cells (CCS) of each oocyte. The expression level of miRNAs and their candidate target genes were compared between CCs of GV and MII oocytes. Our study suggests an inverse relationship exists between the expression levels of miR-514 and EGFR, and miR-642b and PTGER2. Furthermore, we observed that CCs of GV oocytes had higher levels of EGFR and PTGER2 mRNA and lower levels of miR-514 and miR-642b expression compared to those of MII oocytes. The present study demonstrated that miR-514 and miR-642b can regulate oocyte development by targeting EGFR and PTGER2, respectively. Therefore, examination of these miRNAs in CCs could be promising parameters to predict oocyte competence in PCOS patients.

PATIENT EDUCATION AND COUNSELING 2024; 123:108197. [PMID: 38377709 DOI: 10.1016/j.pec.2024.108197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 01/06/2024] [Accepted: 02/05/2024] [Indexed: 02/22/2024]
Abstract
OBJECTIVE To provide an overview of healthcare professionals' experience of PCOS management and identify the relevant facilitators and barriers. METHODS A systematic search was conducted in MEDLINE, EMBASE, CINAHL, Web of Science, and Cochrane CENTRAL database from the earliest available date to April 2023. Qualitative and mixed methods studies that described healthcare professionals' experiences of PCOS management were included. RESULTS A total of 74 findings were extracted from the 8 included studies, which were categorized into facilitators and barriers. The barriers were meta-aggregated into four themes: the weakness of clinical evidence; women's low adherence to PCOS management; various obstacles that healthcare professionals face, and the influence of social environment and culture. The facilitators were meta-aggregated into three themes: chronic disease healthcare plan, communication techniques and healthcare professionals' ability and awareness. CONCLUSION The findings of this study have the potential to improve the care provided to women with PCOS. However, it is important for national health professionals and policy markers to consider the cultural context of their own country when implementing these findings. PRACTICAL IMPLICATIONS This study illustrated several challenges in managing the heterogeneous condition of PCOS and provide insights for the development of medical policies and future research directions.

The early development of offspring born to women with polycystic ovary syndrome: Insights from a prospective birth cohort study in Southwestern China. Psychoneuroendocrinology 2024; 163:106984. [PMID: 38340540 DOI: 10.1016/j.psyneuen.2024.106984] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Revised: 01/28/2024] [Accepted: 02/03/2024] [Indexed: 02/12/2024]
Abstract
PURPOSE This prospective cohort study aimed to investigate the effect of maternal polycystic ovary syndrome (PCOS) on the offspring early development. METHODS A total of 91 mother-child pairs, consisting of 33 PCOS and 58 non-PCOS, were recruited. Peripheral blood tests were performed during 12-16, 24-28, and 32-36 weeks of gestation. Ages & Stages Questionnaires (ASQ) were utilized to assess the motor development of offspring at 27 months of age. Logistic regression models were employed to compare groups and control confounding variables. RESULTS Women with PCOS had a higher level of testosterone and free androgen index than the non-PCOS group in all three detection windows. There were no intergroup differences in any of the five domains of specific ASQ domain scores or the body measurements of the offspring at 27 months old. Stratification by sex of offspring suggested that no significant differences were detected in the male offspring. However, in the female offspring, the PCOS group exhibited lower gross motor scores in female offspring than the non-PCOS group (48.1 ± 11.8 vs. 55.2 ± 8.1, P = 0.027), as well as lower fine motor scores (48.5 ± 8.5 vs. 53.6 ± 11.0, P = 0.028). The gross motor score of female offspring in the PCOS group remained lower even after adjustments. Each 1 ng/mL increase in testosterone at 12-16 weeks of gestation was associated with a decrease in gross motor score of female offspring by 12.2 (95% CI = -23.3 to -1.0, P = 0.038). The highest tertile of testosterone at 12-16 weeks of gestation was associated with a 7.75-point decrease in gross motor score of female offspring compared to the lowest tertile of testosterone (95% CI = -14.9 to -0.6, P = 0.040), with a significant linear trend observed (P for trend = 0.031). CONCLUSIONS The findings of this study suggest that maternal PCOS could exert a negative influence on the gross motor development of female offspring, potentially associated with intrauterine androgen exposure during the early stages of pregnancy.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common chronic condition in women of child-bearing age. There is currently no effective treatment, so early and long-term management is essential. However, there are many problems in the practice of disease management in women with PCOS that make it difficult to achieve good outcomes. OBJECTIVE To explore women's experience of PCOS management and identify the relevant facilitators and barriers to management. SEARCH STRATEGY A structured search was undertaken in five bibliographic databases (MEDLINE, Web of Science, CINAHL, Embase, PubMed, and Cochrane) from the date of establishment of the database up to December 2022. SELECTION CRITERIA All qualitative and mixed-methods studies available in English describing the experience of PCOS management from the patients' perspective were included. DATA COLLECTION AND ANALYSIS The Joanna Briggs Institute Qualitative Assessment and Review Instrument was used to appraise study quality. The evidence was synthesized using a pragmatic meta-aggregative approach guided by the capability, opportunity, and motivation model of behavior (COM-B). MAIN RESULTS A total of 13 studies were included with 85 equivocal findings and 12 credible findings. The findings were meta-aggregated into three themes: (1) capability of women with PCOS, including patients' attitudes toward disease and management, knowledge, and skills of the disease; (2) opportunities in PCOS management, including information about PCOS, diagnostic delay, disease characteristics, disease management plan, and logistical and environmental problems; and (3) motivation in PCOS management, including impact of symptoms, perceived needs, support and feedback, and unpleasant medical experience. CONCLUSIONS This study identifies facilitators and barriers to PCOS management from the patient perspective, which can guide the design and implementation of PCOS management programs for patients. This study also provides information for future research into how the COM-B theory can be incorporated into specific management plans to promote patient action.

Abstract
Hyperandrogenism is an endocrine disorder affecting a large population of reproductive-aged women, thus proportionally high number of fetuses are subjected to prenatal androgenic exposure (PNA). The short-term stimulations at critical ontogenetic stages can wield lasting influences on the health. The most commonly diagnosed conditions in reproductive age women is polycystic ovary syndrome (PCOS). PNA may affect the growth and development of many systems in the whole body and disrupts the normal metabolic trajectory in the offspring of PCOS, contributing to the prevalence of cardiovascular and metabolic diseases (CVMD), including myocardial hypertrophy, hypertension, hyperinsulinemia, insulin resistance, hyperglycemia, obesity, and dyslipidemia, which are the leading causes of hospitalizations in young PCOS offspring. In this review, we focus on the effects of prenatal androgenic exposure on the cardiovascular and metabolic diseases in offspring, discuss the possible pathogenesis respectively, and summarize potential management strategies to improve metabolic health of PCOS offspring. It is expected that the incidence of CVMD and the medical burden will be reduced in the future.

Abstract
Objective Fetal growth can be affected by maternal PCOS and may have an impact on offspring and childhood growth. The current findings across studies are divergent and controversial. This study aims to determine whether maternal PCOS can affect the physical measurements of newborns and to establish the differences in birth weight, length, head, and chest circumference between newborns of mothers with polycystic ovarian syndrome and those of mothers without polycystic ovarian syndrome. Methods In this study, we examined the gestational age, birth weight, length, head circumference, chest circumference, and ponderal index of 75 infants born to mothers with polycystic ovary syndrome (PCOS) and compared them to those of 94 infants born to mothers without PCOS. Result Compared with the other groups, the PCOS group does not show significant differences in anthropometric indices compared to the control group. Infants born to normal and PCOS mothers birth weight were categorized as SGA (small for gestational age) if birth weight was less than the 5th percentile. LGA is large for gestational age if birth weight is greater than the 90th percentile. Other appropriate for gestational age if infant birth weight is between> 5th and < 90th percentile. Significant differences in anthropometric indices like birth weight, head circumference, and Ponderal index were observed in SGA and LGA newborns of normal and PCOS mothers. Conclusion The study findings indicate that neonates born to mothers with PCOS have higher rates of SGA and LGA newborns, and differences in anthropometric indices (birth weight, head circumference, and Ponderal index) were observed between SGA and LGA newborns of PCOS mothers.

Abstract
BACKGROUND Statins are lipid-lowering agents with pleiotropic actions. Experts have proposed that in addition to improving the dyslipidaemia associated with polycystic ovary syndrome (PCOS), statins may also exert other beneficial metabolic and endocrine effects, such as reducing testosterone levels. This is an update of a Cochrane Review first published in 2011. OBJECTIVES To assess the efficacy and safety of statin therapy in women with PCOS who are not actively trying to conceive. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility Group specialised register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHLs, and four ongoing trials registers on 7 November 2022. We also handsearched relevant conference proceedings and the reference lists of relevant trials for any additional studies, and we contacted experts in the field for any further ongoing studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) that evaluated the effects of statin therapy in women with PCOS not actively trying to conceive. Eligible comparisons were statin versus placebo or no treatment, statin plus another agent versus the other agent alone, and statin versus another agent. We performed statistical analysis using Review Manager 5, and we assessed the certainty of the evidence using GRADE methods. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology. Our primary outcomes were resumption of menstrual regularity and resumption of spontaneous ovulation. Our secondary outcomes were clinical and physiological measures including hirsutism, acne severity, testosterone levels, and adverse events. MAIN RESULTS Six RCTs fulfilled the criteria for inclusion. They included 396 women with PCOS who received six weeks, three months, or six months of treatment; 374 women completed the studies. Three studies evaluated the effects of simvastatin and three studies evaluated the effects of atorvastatin. We summarised the results of the studies under the following comparisons. Statins versus placebo (3 RCTs) One trial measured resumption of menstrual regularity as menstrual cycle length in days. We are uncertain if statins compared with placebo shorten the mean length of the menstrual cycle (mean difference (MD) -2.00 days, 95% confidence interval (CI) -24.86 to 20.86; 37 participants; very low-certainty evidence). No studies reported resumption of spontaneous ovulation, improvement in hirsutism, or improvement in acne. We are uncertain if statins compared with placebo reduce testosterone levels after six weeks (MD 0.06, 95% CI -0.72 to 0.84; 1 RCT, 20 participants; very low-certainty evidence), after 3 months (MD -0.53, 95% CI -1.61 to 0.54; 2 RCTs, 64 participants; very low-certainty evidence), or after 6 months (MD 0.10, 95% CI -0.43 to 0.63; 1 RCT, 28 participants; very low-certainty evidence) Two studies recorded adverse events, and neither reported significant differences between the groups. Statins plus metformin versus metformin alone (1 RCT) The single RCT included in this comparison measured resumption of menstrual regularity as the number of spontaneous menses per six months. We are uncertain if statins plus metformin compared with metformin improves resumption of menstrual regularity (MD 0.60 menses, 95% CI 0.08 to 1.12; 69 participants; very low-certainty evidence). The study did not report resumption of spontaneous ovulation. We are uncertain if statins plus metformin compared with metformin alone improves hirsutism measured using the Ferriman-Gallwey score (MD -0.16, 95% CI -0.91 to 0.59; 69 participants; very low-certainty evidence), acne severity measured on a scale of 0 to 3 (MD -0.31, 95% CI -0.67 to 0.05; 69 participants; very low-certainty evidence), or testosterone levels (MD -0.03, 95% CI -0.37 to 0.31; 69 participants; very low-certainty evidence). The study reported that no significant adverse events occurred. Statins plus oral contraceptive pill versus oral contraceptive pill alone (1 RCT) The single RCT included in this comparison did not report resumption of menstrual regularity or spontaneous ovulation. We are uncertain if statins plus the oral contraceptive pill (OCP) improves hirsutism compared with OCP alone (MD -0.12, 95% CI -0.41 to 0.17; 48 participants; very low-certainty evidence). The study did not report improvement in acne severity. We are also uncertain if statins plus OCP compared with OCP alone reduces testosterone levels, because the certainty of the evidence was very low (MD -0.82, 95% CI -1.38 to -0.26; 48 participants). The study reported that no participants experienced significant side effects. Statins versus metformin (2 RCTs) We are uncertain if statins improve menstrual regularity compared with metformin (number of spontaneous menses per six months) compared to metformin (MD 0.50 menses, 95% CI -0.05 to 1.05; 1 RCT, 61 participants, very low-certainty evidence). No studies reported resumption of spontaneous ovulation. We are uncertain if statins compared with metformin reduce hirsutism measured using the Ferriman-Gallwey score (MD -0.26, 95% CI -0.97 to 0.45; 1 RCT, 61 participants; very low-certainty evidence), acne severity measured on a scale of 0 to 3 (MD -0.18, 95% CI -0.53 to 0.17; 1 RCT, 61 participants; very low-certainty evidence), or testosterone levels (MD -0.24, 95% CI -0.58 to 0.10; 1 RCT, 61 participants; very low-certainty evidence). Both trials reported that no significant adverse events had occurred. Statins versus oral contraceptive pill plus flutamide (1 RCT) According to the study report, no participants experienced any significant side effects. There were no available data for any other main outcomes. AUTHORS' CONCLUSIONS The evidence for all main outcomes of this review was of very low certainty. Due to the limited evidence, we are uncertain if statins compared with placebo, or statins plus metformin compared with metformin alone, improve resumption of menstrual regularity. The trial evaluating statin plus OCP versus OCP alone reported neither of our primary outcomes. No other studies reported resumption of spontaneous ovulation. We are uncertain if statins improve hirsutism, acne severity, or testosterone. All trials that measured adverse events reported no significant differences between the groups.

Abstract
BACKGROUND To investigate the relationship between polycystic ovary syndrome (PCOS) in Korean women and childhood growth and obesity of their offspring. METHODS This longitudinal case-control study using the Korean National Health Insurance claims database and the National Health Screening Program for Infants and Children database included women who delivered singletons between January 2007 and December 2008. Offspring's body mass index (BMI) measurements taken between 42 and 80 months of age were compared according to a maternal history of PCOS. RESULTS Among a total of 131,805 participants, 1,213 women had a history of PCOS and 130,592 women did not. Female offspring aged 66-80 months born to women with PCOS had significantly higher BMI than those born to women without PCOS; there was no significant difference in that of male offspring regardless of maternal PCOS. In the generalized estimating equation and multivariable logistic regression analyses, the female offspring born to women with PCOS had a significantly higher risk of obesity during the age of 42-54 and 66-80 months (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.09-2.21 and OR, 1.5; 95% CI, 1.05-2.15, respectively), than those born to women without PCOS, after adjusting for several confounding factors. CONCLUSION Maternal PCOS is independently associated with an increased incidence of childhood obesity in female offspring among Korean women. Women with PCOS should consider the risk of early childhood obesity in their daughters, even if they maintain a healthy weight themselves.

Polycystic ovary syndrome and risk of adverse pregnancy outcomes: a registry linkage study from Massachusetts. Hum Reprod 2022; 37:2690-2699. [PMID: 36149255 PMCID: PMC9627555 DOI: 10.1093/humrep/deac210] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 08/24/2022] [Indexed: 11/13/2022] Open
Abstract
STUDY QUESTION Do women with polycystic ovary syndrome (PCOS) have a greater risk of adverse pregnancy complications (gestational diabetes, preeclampsia, cesarean section, placental abnormalities) and neonatal outcomes (preterm birth, small for gestational age, prolonged delivery hospitalization) compared to women without a PCOS diagnosis and does this risk vary by BMI, subfertility and fertility treatment utilization? SUMMARY ANSWER Deliveries to women with a history of PCOS were at greater risk of complications associated with cardiometabolic function, including gestational diabetes and preeclampsia, as well as preterm birth and prolonged length of delivery hospitalization. WHAT IS KNOWN ALREADY Prior research has suggested that women with PCOS may be at increased risk of adverse pregnancy outcomes. However, findings have been inconsistent possibly due to lack of consistent adjustment for confounding factors, small samples size and other sources of bias. STUDY DESIGN, SIZE, DURATION Massachusetts deliveries among women ≥18 years old during 2013-2017 from state vital records linked to hospital discharges, observational stays and emergency department visits were linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) and the Massachusetts All-Payers Claims Database (APCD). PARTICIPANTS/MATERIALS, SETTING, METHODS PCOS was identified by ICD9 and ICD10 codes in APCD prior to index delivery. Relative risks (RRs) and 95% CI for pregnancy and delivery complications were modeled using generalized estimating equations with a log link and a Poisson distribution to take multiple cycles into account and were adjusted a priori for maternal age, BMI, race/ethnicity, education, plurality, birth year, chronic hypertension and chronic diabetes. Tests for homogeneity investigated differences between maternal pre-pregnancy BMI categories (<30, ≥30, <25 and ≥25 kg/m2) and between non-infertile deliveries and deliveries that used ART or had a history of subfertility (defined by birth certificates, SART CORS records, APCD or hospital records). MAIN RESULTS AND THE ROLE OF CHANCE Among 91 825 deliveries, 3.9% had a history of PCOS. Women with a history of PCOS had a 51% greater risk of gestational diabetes (CI: 1.38-1.65) and a 25% greater risk of preeclampsia (CI: 1.15-1.35) compared to women without a diagnosis of PCOS. Neonates born to women with a history of PCOS were more likely to be born preterm (RR: 1.17, CI: 1.06-1.29) and more likely to have a prolonged delivery hospitalization after additionally adjusting for gestational age (RR: 1.23, CI: 1.09-1.40) compared to those of women without a diagnosis of PCOS. The risk for gestational diabetes for women with PCOS was greater among women with a pre-pregnancy BMI <30 kg/m2. LIMITATIONS, REASONS FOR CAUTION PCOS was defined by ICD documentation prior to delivery so there may be women with undiagnosed PCOS or PCOS diagnosed after delivery included in the unexposed group. The study population is limited to deliveries within Massachusetts among most private insurance payers and inpatient or observational hospitalization in Massachusetts during the follow-up window, therefore there may be diagnoses and or deliveries outside of the state or outside of our sample that were not captured. WIDER IMPLICATIONS OF THE FINDINGS In this population-based study, women with a history of PCOS were at greater risk of pregnancy complications associated with cardiometabolic function and preterm birth. Obstetricians should be aware of patients' PCOS status and closely monitor for potential pregnancy complications to improve maternal and infant perinatal health outcomes.

Abstract
STUDY QUESTION Does maternal polycystic ovarian syndrome (PCOS) affect the timing of pubertal development in daughters and sons? SUMMARY ANSWER Maternal PCOS was associated with earlier adrenarche in daughters. WHAT IS KNOWN ALREADY Female adolescents with PCOS often experience earlier adrenarche compared to adolescents without PCOS, due to hyperandrogenism. Likewise, they usually have hyperandrogenism during pregnancy, which might potentially affect the development of the foetus, including its future reproductive health. STUDY DESIGN, SIZE, DURATION In this population-based cohort study, we included 15 596 mothers-child pairs from the Danish National Birth Cohort (DNBC) Puberty Cohort, who were followed from foetal life until full sexual maturation or 18 years of age. PARTICIPANTS/MATERIALS, SETTING, METHODS Using register-based and self-reported information on maternal PCOS and menstrual irregularities, collected during pregnancy, we categorized the mothers as having PCOS (n = 251), oligomenorhoea (n = 134), 'other menstrual irregularities' (n = 2411) or no menstrual abnormalities (reference group, n = 12 800). The children provided self-reported information on pubertal development every 6 months from the age of 11 years. The main outcome measures were adjusted mean age differences (in months) at attaining several individual pubertal milestones using an interval-censored regression model, as well as the average difference in age at attaining all pubertal milestones combined into a single estimate using Huber-White robust variance estimation. MAIN RESULTS AND THE ROLE OF CHANCE We found that maternal PCOS was associated with an accelerated pubertal development in daughters with an overall average difference of -3.3 (95% CI: -6.3; -0.4) months based on all pubertal milestones compared to the reference group. When further looking into the average difference for adrenarche only (pubarche, axillary hair and acne), the average difference was -5.4 (95% CI: -8.7; -2.1) months compared to the reference group; whereas thelarche and menarche did not occur earlier in daughters of mothers with PCOS (average difference: -0.8 (95% CI: -3.9; 2.4) months). Oligomenorrhoea and 'other menstrual irregularities' were not associated with pubertal development in daughters. Neither PCOS, oligomenorrhoea nor 'other menstrual irregularities' were associated with pubertal development in sons. LIMITATIONS, REASONS FOR CAUTION We expect some degree of non-differential misclassification of maternal PCOS and menstrual irregularities as well as pubertal development in the children. WIDER IMPLICATIONS OF THE FINDINGS Maternal PCOS might accelerate adrenarche in daughters. Whether this is due to genetics, epigenetics or prenatal programming by hyperandrogenism in foetal life remains unsolved. The results from the present study can be generalized to Caucasian populations. STUDY FUNDING/COMPETING INTEREST(S) The study is funded by the Faculty of Health at Aarhus University. The authors have no financial relationships or competing interests to disclose. TRIAL REGISTRATION NUMBER N/A.

Abstract
STUDY QUESTION Do children whose mothers have polycystic ovary syndrome (PCOS) have an increased risk of morbidity? SUMMARY ANSWER Maternal PCOS is associated with an increased risk of infection, allergy and other childhood morbidity. WHAT IS KNOWN ALREADY PCOS is associated with higher rates of gestational diabetes, pre-eclampsia and preterm delivery, but the long-term impact on child health is poorly understood. STUDY DESIGN, SIZE, DURATION We conducted a retrospective longitudinal cohort study of 1 038 375 children in Quebec between 2006 and 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS We included 7160 children whose mothers had PCOS and 1 031 215 unexposed children. Outcomes included child hospitalization for infectious, allergic, malignant and other diseases before 13 years of age. We estimated hazard ratios (HRs) and 95% CI for the association of PCOS with childhood morbidity in adjusted Cox proportional hazards regression models. MAIN RESULTS AND THE ROLE OF CHANCE Children exposed to PCOS were hospitalized at a rate of 68.9 (95% CI 66.2-71.8) per 1000 person-years, whereas unexposed children were hospitalized at a rate of 45.3 (95% CI 45.1-45.5) per 1000 person-years. Compared with no exposure, maternal PCOS was associated with 1.32 times the risk of any childhood hospitalization (95% CI 1.26-1.40), 1.31 times the risk of infectious disease hospitalization (95% CI 1.25-1.38) and 1.47 times the risk of allergy-related hospitalization (95% CI 1.31-1.66). Risk of hospitalization was also elevated for childhood metabolic (HR 1.59, 95% CI 1.16-2.18), gastrointestinal (HR 1.72, 95% CI 1.53-1.92), central nervous system (HR 1.74, 95% CI 1.46-2.07) and otologic disorders (HR 1.34, 95% CI 1.26-1.43). Subgroup analyses suggested that there was little difference in the association of PCOS with hospitalization among boys (HR 1.31, 95% CI 1.24-1.39) and girls (HR 1.34, 95% CI 1.26-1.43). LIMITATIONS, REASONS FOR CAUTION We analyzed severe childhood morbidity requiring hospitalization, not mild diseases treated in ambulatory clinics. We lacked data on ethnicity, education and physical activity, and cannot rule out residual confounding. WIDER IMPLICATIONS OF THE FINDINGS Our findings suggest that maternal PCOS is associated with an increased risk of childhood morbidity.

Abstract
Introduction A paucity of data exists regarding pregnancy outcome data in women with polycystic ovarian syndrome (PCOS). Therefore, we conducted this study to compare the pregnancy outcomes of women with and without in Indian population. Materials and methods A total of 102 antenatal pregnant women aged between 18 and 45 years were included in this study conducted at the Department of Obstetrics and Gynecology, Pradyumna Bal Memorial Hospital, Kalinga Institute of Medical Sciences, Bhubaneswar, India. Fifty-one women had PCOS, and 51 women served as controls. We recorded patient demographic, clinical, menstrual, and pregnancy data for each group. All participants were monitored until delivery, and we recorded maternal outcomes, including spontaneous abortion, preterm birth, gestational diabetes mellitus (GDM), and pregnancy-induced hypertension (PIH). We used IBM SPSS Statistics version 20.0 for Windows (Armonk, NY: IBM Corp.) for statistical analysis and the chi-square test to analyze relationships in categorical variables. Results Most participants were aged between 20 and 30 years (64.7%). A high body mass index (BMI) was twice as common in women with PCOS than the control group. Most women with PCOS with pregnancy complications were overweight (62.7%) with a BMI of 25 to 29.9 kg/m2. A majority of women in the PCOS group (86.3%) required reproductive technology assistance, while none in the control group needed the same type of assistance. In the PCOS group, spontaneous abortions (SAB) occurred in 5.9%, GDM occurred in 17.6%, PIH in 21.6%, and preterm births in 33.3%. By contrast, the control group saw SAB occur in only 3.9%, GDM occurred in 9.8%, PIH was identical in 21.6%, and preterm births occurred in 17.6% of women without PCOS. Cesarian delivery occurred in 64.7% of women with PCOS, while only 39.2% of women without PCOS had cesarian delivery was statistically not significant. Conclusion We conducted this study to assess the impact of PCOS on pregnancy against pregnant women without PCOS. Pregnant women with PCOS were more likely to experience complications such as SAB, GDM, and preterm birth than pregnant women without PCOS. Therefore, pregnancies in women with PCOS are high-risk pregnancies that require frequent and timely antenatal care.

Reprod Biol Endocrinol 2022; 20:30. [PMID: 35130922 PMCID: PMC8819934 DOI: 10.1186/s12958-022-00905-6] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Accepted: 01/30/2022] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Polycystic Ovary Syndrome (PCOS) is an endocrine disorder that affects women in reproductive age and represents an unfavourable risk factor for several pregnancy and perinatal outcomes. Despite, no guidelines or pharmaceutical strategies for treating PCOS during pregnancy are available. The aim of this study is to determine the association between polycystic ovary syndrome with or without metformin and the pregnancy, perinatal outcomes as well as the risk of obesity in children born to these mothers. METHODS In this nationwide population-based cohort study based in Swedish population, all singleton births (n = 1,016,805) from 686,847 women since 2006 up to 2016 were included. Multivariable logistic and Cox regression modelling with odds ratios (OR) and hazard ratios (HR) and 95% confidence intervals were used to study the association between the exposure of maternal PCOS, metformin during pregnancy (or the combination of both) and: 1) Pregnancy outcomes: preeclampsia, gestational diabetes, caesarean section, and acute caesarean section, 2) Perinatal outcomes: preterm birth, stillbirth, low birth weight, macrosomia, Apgar < 7 at 5 min, small for gestational age and large for gestational age, and 3) Childhood Obesity. RESULTS PCOS in women without metformin use during pregnancy was associated with higher risks of preeclampsia (OR = 1.09, 1.02-1.17), gestational diabetes (OR = 1.71, 1.53-1.91) and caesarean section (OR = 1.08, 1.04-1.12), preterm birth (OR = 1.30, 1.23-1.38), low birth weight (OR = 1.29, 1.20-1.38), low Apgar scores (OR = 1.17, 1.05-1.31) and large for gestational age (OR = 1.11, 1.03-1.20). Metformin use during pregnancy (in women without PCOS) was associated with a 29% lower risks of preeclampsia (OR = 0.71, 0.51-0.97), macrosomia and large for gestational age. Obesity was more common among children born to mothers with PCOS without metformin (HR = 1.61, 1.44-1.81); and those with metformin without PCOS (HR = 1.67, 1.05-2.65). PCOS with metformin was not associated with any adverse outcome. CONCLUSION PCOS was associated with increased risks of adverse pregnancy and perinatal outcomes and childhood obesity. Metformin appears to reduce these risks in mothers with polycystic ovary syndrome and their children; but may increase the risk of childhood-obesity in children form women without PCOS.

Metformin exposure, maternal PCOS status and fetal venous liver circulation: A randomized, placebo-controlled study. PLoS One 2022; 17:e0262987. [PMID: 35089960 PMCID: PMC8797196 DOI: 10.1371/journal.pone.0262987] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Accepted: 11/16/2021] [Indexed: 11/19/2022] Open
Abstract
Background Metformin is prescribed to women with polycystic ovary syndrome (PCOS) to prevent pregnancy complications. Children exposed to metformin vs. placebo in utero, have increased head circumference at birth and are more overweight and obese at 8 years of age. Also, maternal PCOS-status seems to alter the long-term cardio-metabolic health of offspring. We hypothesized that the long-term effects of metformin-exposure and/or maternal PCOS may be mediated by circulatory adaptations during fetal life. Material and methods This is a sub-study of a larger double-blinded, placebo-controlled trial, where women with PCOS were randomized to metformin (2g/day) or placebo in pregnancy, a total of 487 women. A sub-group of participants (N = 58) took part in this sub-study and had an extended ultrasound examination at gestational week 32, including blood flow velocity and diameter measurements of the umbilical vein (UV), the ductus venosus (DV) and the portal vein (PV). Blood flow volume was calculated and adjusted for estimated fetal weight (EFW) (normalized flow). Metformin exposed fetuses were compared to placebo exposed fetuses. Fetuses of mothers with PCOS (metformin [n = 30] and placebo [n = 28]) were compared to a low-risk reference population (N = 160) by z-score statistics. Results There was no difference in fetal liver flow between metformin vs. placebo-exposed fetuses. Fetuses of mothers with PCOS had higher EFW (0.63 [95% CI 0.44–0.83] p<0.001), lower normalized UV, DV, PV, and lower total venous liver blood flows than the reference population. Conclusion Metformin during pregnancy did not affect fetal liver blood-flow. In our population, maternal PCOS-status was associated with reduced total venous liver blood-flow, which may explain altered growth and metabolism later in life.

Adverse Effects of Polycystic Ovarian Syndrome on Pregnancy Outcomes in Women With Frozen-Thawed Embryo Transfer: Propensity Score-Matched Study. Front Endocrinol (Lausanne) 2022; 13:878853. [PMID: 35733779 PMCID: PMC9207193 DOI: 10.3389/fendo.2022.878853] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Accepted: 04/26/2022] [Indexed: 11/13/2022] Open
Abstract
PURPOSE This work aimed to evaluate the adverse effect of polycystic ovary syndrome (PCOS) on pregnancy outcomes of singletons after vitrification in women with frozen-thawed embryo transfer (FET). METHODS Patients with/without PCOS who underwent FET from January 2013 and December 2018 were included. Propensity score matching (PSM) was used to reduce the influence of bias. Logistic regression was applied to identify the risk factors of adverse pregnancy outcomes of singletons in women with PCOS. RESULT After PSM, the PCOS group had shorter gestational age (P<0.001) and lower newborn birth weight than the non-PCOS group (P=0.045). Compared with the non-PCOS group, the PCOS group had an increased risk of gestational diabetes mellitus (GDM) and pregnancy-induced hypertension (PIH) (P<0.001), placenta and membrane abnormality (P<0.001), stillbirth (P<0.001), neonatal complication (P=0.014), and miscarriage rate (P<0.001). Neonatal complication was associated with parity (adjusted OR=1.202, 95% CI=1.002-1.443, P=0.048) and basal P level (adjusted OR=1.211, 95% CI=1.021-1.436, P=0.028). According to multivariable logistic regression analysis, the miscarriage rate was related to parity (adjusted OR=1.201, 95% CI=1.057-1.166, P=0.005) and basal E2 (adjusted OR=1.002, 95% CI=1.000-1.004, P=0.019) and P levels on the day of embryo transfer (adjusted OR=0.971, 95% CI=0.957-0.985, P<0.001). CONCLUSIONS Compared with non-PCOS women, women with PCOS have a higher risk of GDM and PIH, and neonatal complications and therefore require additional care during pregnancy and parturition.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting women at reproductive age. PCOS diagnosis (Rotterdam criteria) is based on the presence of two out of three criteria; clinical and/or biochemical hyperandrogenism, oligo- or an-ovulation and polycystic ovaries. PCOS women suffer from a constellation of reproductive and metabolic abnormalities including obesity and insulin resistance. PCOS women also have increased blood pressure and increased risk of cardiovascular diseases (CVD). In-utero, offspring of PCOS women are exposed to altered maternal hormonal environment and maternal obesity (for most of PCOS women). Offspring of PCOS women could also be subject to genetic susceptibility, the transgenerational transmission of some of the PCOS traits or epigenetic changes. Offspring of PCOS women are commonly reported to have an abnormal birth weight, which is also a risk factor for developing CVD and hypertension later in life. Although studies have focused on the growth pattern, reproductive and metabolic health of children of PCOS women, very limited number of studies have addressed the risk of hypertension and CVD in those offspring particularly as they age. The current narrative review is designed to summarize the available literature (both human studies and experimental animal studies) and highlight the gaps in addressing hypertension and CVD risks in offspring of PCOS women or hyperandrogenemic female animal models.

Abstract
A potential correlation between polycystic ovary syndrome (PCOS) and asthma, used to be identified as diseases originating from two independent systems, has been supported by increasing evidence. From an epidemiological perspective, mounting studies have confirmed that women suffering from PCOS exhibit increased susceptibility to asthma. Meanwhile, PCOS and asthma seem to share several mutual pathological conditions, such as metabolic disorders, hormonal fluctuation, proinflammatory state, etc. Here, we further elucidate the correlation between asthma and PCOS by focusing on the internal common pathophysiology and adverse influences on women's health. Understanding the internal connection between PCOS and asthma may shed light on developing new prevention and control strategies to fight against these conditions.

Abstract
OBJECTIVE To investigate whether polycystic ovary syndrome (PCOS) is associated with increased risk of stillbirth and whether any such association is linked to PCOS with a severe hyperandrogenic profile. DESIGN Nationwide register-based cohort study. SETTING Sweden. POPULATION The cohort consisted of women giving birth to singleton infants in 1997-2015. All women with a diagnosis of PCOS in the period 1997-2017 and a randomly selected reference group of women without PCOS diagnosis were included. PCOS with a severe hyperandrogenic profile was defined as a PCOS diagnosis with at least two dispensations of prescribed anti-androgens during 2005-2017. METHODS The risk of stillbirth in women with PCOS was estimated through multiple logistic regression, using women without PCOS as a reference. Risks were expressed as adjusted odds ratios (aORs) with 95% confidence intervals (95% CIs), adjusted for maternal age, parity, body mass index, type-1 diabetes, educational level and country of birth. MAIN OUTCOME MEASURES Stillbirth, at ≥22 weeks of gestation in 2008-2015 and at ≥28 weeks of gestation in 1997-2007. RESULTS Compared with women without PCOS (n = 241 750), women with PCOS (n = 41 851) had a 50% increased risk of stillbirth (aOR 1.50, 95% CI 1.28-1.77). The incidence of stillbirth in women with PCOS was particularly increased at term. Women with PCOS and a severe hyperandrogenic profile (n = 13 713) did not have a stronger association with stillbirth than women with PCOS who did not have such a profile. CONCLUSIONS PCOS is associated with stillbirth and should be considered as a possible risk factor in antenatal care. Further research is warranted to investigate possible causal mechanisms. TWEETABLE ABSTRACT Women with PCOS have increased risk of stillbirth, and the incidence is particularly increased at term.

Abstract
While there exists some evidence indicating a higher prevalence of asthma in polycystic ovary syndrome (PCOS) patients, whether PCOS is an independent risk factor for asthma remains debatable. In this report, a systematic review and meta-analysis were performed to assess the association between PCOS and asthma. Using of the terms "PCOS," "polycystic ovary syndrome," "polycystic ovarian syndrome," "Stein Leventhal Syndrome," "asthma," and "wheezing," PubMed, Embase, Web of Science, Scopus, Cochrane Trial Register, China National Knowledge Infrastructure (CNKI), and Wanfang databases were searched for studies published from their inceptions to February 2021. The data were extracted and a meta-analysis was conducted under the guidance of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A random-effects model was used to calculate the odds ratios (OR) and 95% confidence intervals (95% CI). A total of 6 articles involving 26,876 PCOS women and 156,143 healthy controls were included in this survey. Our results indicate that PCOS patients showed an increased risk of asthma (OR = 1.75, 95% CI = 1.40-2.19, I2 = 91.2%, P = 0.000, random-effects model). No statistically significant differences were obtained when these data were stratified by region, diagnostic criteria for asthma, and study design. PCOS is associated with a higher risk of asthma, a relationship which is independent of region, diagnostic criteria for bronchitis, and study design.

Abstract
Robust evidence of fetal programming of adult disease has surfaced in the last several decades. Human and preclinical investigations of intrauterine insults report perturbations in placental nutrient sensing by the mechanistic target of rapamycin (mTOR). This review focuses on pregnancy complications associated with placental mTOR regulation, such as fetal growth restriction (FGR), fetal overgrowth, gestational diabetes mellitus (GDM), polycystic ovarian syndrome (PCOS), maternal nutrient restriction (MNR), preeclampsia (PE), maternal smoking, and related effects on offspring birthweight. The link between mTOR-associated birthweight outcomes and offspring metabolic health trajectory with a focus on sexual dimorphism are discussed. Both human physiology and animal models are summarized to facilitate in depth understanding. GDM, PCOS and fetal overgrowth are associated with increased placental mTOR, whereas FGR, MNR and maternal smoking are linked to decreased placental mTOR activity. Generally, birth weight is reduced in complications with decreased mTOR (i.e., FGR, MNR, maternal smoking) and higher with increased mTOR (GDM, PCOS). Offspring display obesity or a higher body mass index in childhood and adulthood, impaired glucose and insulin tolerance in adulthood, and deficiencies in pancreatic beta-cell mass and function compared to offspring from uncomplicated pregnancies. Defining causal players in the fetal programming of offspring metabolic health across the lifespan will aid in stopping the vicious cycle of obesity and type II diabetes.

Abstract
Background Polycystic ovary syndrome (PCOS) is quite common among women of reproductive age and can cause infertility and adverse pregnancy outcomes. Current studies on PCOS mainly focus on the effect of PCOS on pregnancy. So far, it remains unelucidated whether a history of infertility or early pregnancy loss (EPL) has differential effects on obstetric outcomes for PCOS women. Methods This is a retrospective case control study. Ninety-two Chinese PCOS patients with a history of EPL or infertility were recruited in our study. A total of 112 Chinese non-PCOS patients with a history of EPL or infertility were taken as control group. Measurements included anthropometric data, serum total testosterone, fasting and two-hour plasma glucose levels, and antral follicle count. After they got pregnant (naturally or via assisted reproductive technology), all obstetric outcomes were observed and analyzed. Results PCOS women with a history of EPL showed a much higher cesarean section (CS) rate than PCOS women with primary infertility. PCOS women with a history of EPL showed a much higher possibility of GDM (gestational diabetes mellitus) compared with PCOS women with primary infertility. PCOS women with a history of EPL showed a much higher possibility of GDM compared with non-PCOS women with a history of EPL. PCOS women with a history of EPL showed increased possibility of GDM as their BMI increased. When BMI is above 28, the incidence of GDM is significantly higher in PCOS women with a history of EPL compared with that in PCOS women with infertility. Conclusion Both a history of EPL and obesity are risk factors for GDM for PCOS women, and higher BMI indicates a higher possibility of GDM among PCOS women with a history of EPL. Timely intervention is in need for PCOS women with EPL and a higher BMI.

Abstract
Objective Polycystic ovary syndrome (PCOS) is a common endocrine disorder, with potential effects on offspring both genetically and through altered intrauterine environment. Metformin, which ameliorate hormonal disturbances in non-pregnant women with PCOS is increasingly used in pregnancy. It passes the placenta, and the evidence on potential consequences for offspring endocrine development is scarce. We explore the potential effects of maternal PCOS status and intrauterine metformin exposure on offspring steroid hormone levels. Design This is a follow-up study of 5–10 years old children from the PregMet-study–a randomized controlled trial comparing metformin (2000 mg/day) to placebo during PCOS pregnancies. Of the 255 children invited, 117 (46%) were included. Methods There was no intervention in this follow-up study. Outcomes were serum levels of androstenedione, testosterone, SHBG, cortisol, 17-hydroxyprogesterone, 11-deoxycortisol and calculated free testosterone converted to gender-and age adjusted z-scores from a Norwegian reference population. These were compared in i) placebo-exposed children versus children from the reference population (z-score zero) by the deviation in z-score by one-sample t-tests and ii) metformin versus placebo-exposed children by two-sample t-tests. Holm-Bonferroni adjustments were performed to account for multiple endpoints. Results Girls of mothers with PCOS (n = 30) had higher mean z-scores of androstenedione (0.73 (95% confidence interval (CI) 0.41 to 1.06), p<0.0001), testosterone (0.76 (0.51 to 1.00), p<0.0001), and free testosterone (0.99 (0.67 to 1.32), p<0.0001) than the reference population. Metformin-exposed boys (n = 31) tended to have higher 11-deoxycortisol z-score than placebo-exposed boys (n = 24) (mean difference 0.65 (95% CI 0.14–1.17), p = 0.014). Conclusion Maternal PCOS status was associated with elevated androgens in 5- to 10-year-old daughters, which might indicate earlier maturation and increased risk of developing PCOS. An impact of metformin in pregnancy on steroidogenesis in children born to mothers with PCOS cannot be excluded. Our findings need confirmation in studies that include participants that have entered puberty.

Abstract
STUDY QUESTION Are children of mothers with polycystic ovary syndrome (PCOS) or anovulatory infertility at increased risks of obesity or diabetes? SUMMARY ANSWER Maternal PCOS/anovulatory infertility is associated with an increased risk of offspring obesity from early age and diabetes in female offspring from late adolescence. WHAT IS KNOWN ALREADY Women with PCOS often have comorbid metabolic disorders such as obesity and diabetes, and children of mothers with PCOS have an increased risk of subtle signs of cardiometabolic alterations. STUDY DESIGN, SIZE, DURATION This was a nationwide cohort study of all live births (n = 1 105 997) during 1996-2014 in Finland, excluding those with maternal diagnoses sharing signs and symptoms with PCOS (n = 8244). A total of 1 097 753 births were included and followed up until 31 December 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS National registries were linked to identify births with maternal PCOS or anovulatory infertility (n = 24 682). The primary outcomes were diagnoses of obesity (ICD-10: E65, E66) and diabetes (ICD-10: E10-E14) in offspring recorded in the Finnish Care Register for Health Care. Cox proportional hazards regression was modeled to analyze the risk of offspring obesity and diabetes in relation to prenatal exposure to maternal PCOS/anovulatory infertility. Differently adjusted models and stratified analyses were used to assess whether the risk was modified by maternal obesity or diabetes diagnoses, pre-pregnancy BMI, fertility treatment or perinatal problems. MAIN RESULTS AND THE ROLE OF CHANCE Exposure to maternal PCOS/anovulatory infertility was associated with a higher cumulative incidence of obesity in the children (exposed: 1.83%; 95% CI 1.66-2.00% vs unexposed: 1.24%; 95% CI 1.22-1.26%). Accounting for birth factors and maternal characteristics such as obesity and diabetes diagnoses, the hazard ratio (HR) for obesity was increased in offspring below 9 years of age (HR 1.58; 95% CI 1.30-1.81), and in those 10-16 years of age (HR 1.37; 95% CI 1.19-1.57), but not in those aged 17-22 years (HR 1.24; 95% CI 0.73-2.11). Sex-stratified analyses revealed similar risk estimates for boys (HR 1.48; 95% CI 1.31-1.68) and girls (HR 1.45; 95% CI 1.26-1.68). Notably, the joint effect of PCOS/anovulatory infertility and BMI-based pre-pregnancy obesity on offspring obesity (HR 8.89; 95% CI 7.06-11.20) was larger than that of either PCOS/anovulatory infertility or obesity alone. Furthermore, PCOS/anovulatory infertility was associated with offspring obesity in children without perinatal problems (HR 1.27; 95% CI 1.17-1.39), with larger effect size for maternal PCOS/anovulatory infertility and joint perinatal problems (HR 1.61; 95% CI 1.35-1.91). However, the risk estimates were comparable between maternal PCOS/anovulatory infertility with (HR 1.54; 95% CI 1.17-2.03) and without fertility treatment (HR 1.46; 95% CI 1.32-1.61). For offspring diabetes, the HR was increased only between 17 and 22 years of age (HR 2.06; 95% CI 1.23-3.46), and specifically for Type 1 diabetes in females (HR 3.23; 95% CI 1.41-7.40). LIMITATIONS, REASONS FOR CAUTION The prevalence of PCOS/anovulatory infertility in this study was 2.2%, lower than that reported in previous studies. In addition, the incidence of obesity in offspring was lower than that reported in studies based on measured or self-reported weight and height and may include mainly moderate and severe obesity cases who needed and/or actively sought medical care. Moreover, mothers with PCOS/anovulatory infertility were identified based on ICD codes, with no information on PCOS phenotypes. Furthermore, maternal pre-pregnancy BMI was available only from 2004. The PCOS/anovulatory infertility association with female offspring diabetes was based on only a few cases. Mothers' weight gain during pregnancy, use of fertility treatment other than fresh or frozen IVF/ICSI, offspring lifestyle, as well as fathers' age, medical disorders or medication prescriptions were not available for this study. WIDER IMPLICATIONS OF THE FINDINGS These findings support that prenatal PCOS/anovulatory infertility exposure influences metabolic health in the offspring from early age.

Penova-Veselinovic B, Melton PE, Huang RC, Yovich JL, Burton P, Wijs LA, Hart RJ. DNA methylation patterns within whole blood of adolescents born from assisted reproductive technology are not different from adolescents born from natural conception. Hum Reprod 2021; 36:2035-2049. [PMID: 33890633 DOI: 10.1093/humrep/deab078] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Revised: 03/04/2021] [Indexed: 12/18/2022] Open
Abstract
STUDY QUESTION Do the epigenome-wide DNA methylation profiles of adolescents born from ART differ from the epigenome of naturally conceived counterparts? SUMMARY ANSWER No significant differences in the DNA methylation profiles of adolescents born from ART [IVF or ICSI] were observed when compared to their naturally conceived, similar aged counterparts. WHAT IS KNOWN ALREADY Short-term and longer-term studies have investigated the general health outcomes of children born from IVF treatment, albeit without common agreement as to the cause and underlying mechanisms of these adverse health findings. Growing evidence suggests that the reported adverse health outcomes in IVF-born offspring might have underlying epigenetic mechanisms. STUDY DESIGN, SIZE, DURATION The Growing Up Healthy Study (GUHS) is a prospective study that recruited 303 adolescents and young adults, conceived through ART, to compare various long-term health outcomes and DNA methylation profiles with similar aged counterparts from Generation 2 from the Raine Study. GUHS assessments were conducted between 2013 and 2017. The effect of ART on DNA methylation levels of 231 adolescents mean age 15.96 ± 1.59 years (52.8% male) was compared to 1188 naturally conceived counterparts, 17.25 ± 0.58 years (50.9% male) from the Raine Study. PARTICIPANTS/MATERIALS, SETTING, METHODS DNA methylation profiles from a subset of 231 adolescents (13-19.9 years) from the GUHS, generated using the Infinium Methylation Epic Bead Chip (EPIC) array were compared to 1188 profiles from the Raine Study previously measured using the Illumina 450K array. We conducted epigenome-wide association approach (EWAS) and tested for an association between the cohorts applying Firth's bias reduced logistic regression against the outcome of ART versus naturally conceived offspring. Additionally, within the GUHS cohort, we investigated differences in methylation status in fresh versus frozen embryo transfers, cause of infertility as well as IVF versus ICSI conceived offspring. Following the EWAS analysis we investigated nominally significant probes using Gene Set Enrichment Analysis (GSEA) to identify enriched biological pathways. Finally, within GUHS we compared four estimates (Horvath, Hanuum, PhenoAge [Levine], and skin Horvath) of epigenetic age and their correlation with chronological age. MAIN RESULTS AND THE ROLE OF CHANCE Between the two cohorts, we did not identify any DNA methylation probes that reached a Bonferroni corrected P-value < 1.24E-0.7. When comparing IVF versus ICSI conceived adolescents within the GUHS cohort, after adjustment for participant age, sex, maternal smoking, multiple births, and batch effect, three methylation probes (cg15016734, cg26744878 and cg20233073) reached a Bonferroni correction of 6.31E-08. After correcting for cell count heterogeneity, two of the aforementioned probes remained significant and an additional two probes (cg 0331628 and cg 20235051) were identified. A general trend towards hypomethylation in the ICSI offspring was observed. All four measures of epigenetic age were highly correlated with chronological age and showed no evidence of accelerated epigenetic aging within their whole blood. LIMITATIONS, REASONS FOR CAUTION The small sample size coupled with the use of whole blood, where epigenetic differences may occur in other tissue. This was corrected by the utilized statistical method that accounts for imbalanced sample size between groups and adjusting for cell count heterogeneity. Only a small portion of the methylome was analysed and rare individual differences may be missed. WIDER IMPLICATIONS OF THE FINDINGS Our findings provide further reassurance that the effects of the ART manipulations occurring during early embryogenesis, existing in the neonatal period are indeed of a transient nature and do not persist into adolescence. However, we have not excluded that alternative epigenetic mechanisms may be at play.

Abstract
Objective To evaluate the effects of body mass index (BMI) in patients with polycystic ovary syndrome (PCOS) undergoing controlled ovarian stimulation (COS) with intrauterine insemination (IUI). Methods This retrospective study evaluated couples with PCOS undergoing COS and IUI. The relationship between cumulative IUI pregnancy outcomes and BMI, treatment cycles, treatment schemes, number of dominant follicles, endometrial thickness, infertility duration and type of infertility was analysed. Results The study evaluated 831 IUI cycles in 451 couples with PCOS. Compared with normoweight women, overweight and obese women required more human menopausal gonadotropin (hMG) doses and more days of COS. Gestational diabetes mellitus occurred more frequently in the obese group than in the other BMI groups. The clinical pregnancy and live birth rates in the hMG, clomiphene citrate (CC) + hMG and letrozole (LE) + hMG groups were significantly higher than those in the CC and LE groups. The clinical pregnancy rate was higher in the secondary infertility group compared with the primary infertility group. Conclusion Obese women might require more hMG doses and more days of COS to overcome the effects of weight. As BMI increases, the incidence of gestational diabetes might also increase. The number of cycles and type of infertility may have a predictive value for pregnancy outcomes.

Abstract
STUDY QUESTION Does the inheritance of polycystic ovary syndrome (PCOS) susceptibility single-nucleotide polymorphism affect the phenotype of offspring? SUMMARY ANSWER Male offspring who inherit PCOS-related genetic variations from PCOS mothers were more susceptible to developing the metabolic abnormality in their later life. WHAT IS KNOWN ALREADY Genetic factors are considered the major etiology of PCOS. Previous studies have highlighted that offspring of women with PCOS had an increased risk of the same disease or PCOS-like symptoms. STUDY DESIGN, SIZE, DURATION The study involved 172 children born to women with PCOS and 529 children born to non-PCOS women. All offspring were conceived by assisted reproductive technologies. PARTICIPANTS/MATERIALS, SETTING, METHODS The offspring ranged from 1 to 8 years old. Metabolic phenotype analyses were performed in offspring aged from 2 to 8 (N = 619). Sanger sequencing, TaqMan and Sequenom MassARRAY were used to sequence the samples. MAIN RESULTS AND THE ROLE OF CHANCE In male offspring, the fasting insulin (FINS) (P = 0.037) homeostasis model assessment of insulin resistance (HOMA-IR) (P = 0.038) and the homeostasis model assessment of pancreatic beta-cell function (HOMA-β) (P = 0.038) levels were higher in offspring of PCOS mothers compared to controls. In female offspring, PCOS offspring had a significantly higher anti-Müllerian hormone levels (P = 0.001) compared to those from control mothers. In male offspring of PCOS mothers, subjects with a T allele at rs2349415 in the gene FSHR had higher FINS (P = 0.023), HOMA-IR (P = 0.030) and HOMA-β levels (P = 0.013) than those in the homozygous CC group. The same increased trend in FINS, HOMA-IR and HOMA-β levels could be found in the CC and TC group in rs2268361 located in gene FSHR compared to the TT group (P = 0.029, P = 0.030, P = 0.046, respectively). As for rs10818854 in the DENND1A gene, the AA and AG group had a higher FINS (P = 0.037) and HOMA-β (P = 0.008) levels than the homozygous CC group. LIMITATIONS, REASONS FOR CAUTION Firstly, the offspring may be too young to see any phenotype changes. Secondly, this study only analyzed the differences of genotype frequency using the dominant model instead of all three models due to the limited sample size of the homozygous model. The results, therefore, should be replicated and performed in a larger sample size population. Thirdly, environmental impacts cannot be ruled out. WIDER IMPLICATIONS OF THE FINDINGS The findings presented in this thesis add to our understanding the changes in offspring born to PCOS women and remind us to consider early intervention to avoid more severe effects.

Outcome of in-vitro oocyte maturation in patients with PCOS: does phenotype have an impact? Hum Reprod 2021; 35:2272-2279. [PMID: 32951028 DOI: 10.1093/humrep/deaa190] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 07/02/2020] [Indexed: 12/23/2022] Open
Abstract
STUDY QUESTION Does the phenotype of patients with polycystic ovary syndrome (PCOS) affect clinical outcomes of ART following in-vitro oocyte maturation? SUMMARY ANSWER Cumulative live birth rates (CLBRs) after IVM were significantly different between distinct PCOS phenotypes, with the highest CLBR observed in patients with phenotype A/HOP (= hyperandrogenism + ovulatory disorder + polycystic ovaries), while IVM in patients with phenotype C/HP (hyperandrogenism + polycystic ovaries) or D/OP (ovulatory disorder + polycystic ovaries) resulted in lower CLBRs (OR 0.26 (CI 0.06-1.05) and OR 0.47 (CI 0.25-0.88), respectively, P = 0.03). WHAT IS KNOWN ALREADY CLBRs in women with hyperandrogenic PCOS phenotypes (A/HOP and C/HP) have been reported to be lower after ovarian stimulation (OS) and ART when compared to CLBR in women with a normo-androgenic PCOS phenotype (D/OP) and non-PCOS patients with a PCO-like ovarian morphology (PCOM). Whether there is an influence of the different PCOS phenotypes on success rates of IVM has been unknown. STUDY DESIGN, SIZE, DURATION This was a single-centre, retrospective cohort study including 320 unique PCOS patients performing their first IVM cycle between April 2014 and January 2018 in a tertiary referral hospital. PARTICIPANTS/MATERIALS, SETTING, METHODS Baseline patient characteristics and IVM treatment cycle data were collected. The clinical outcomes following the first IVM embryo transfer were retrieved, including the CLBR defined as the number of deliveries with at least one live birth resulting from one IVM cycle and all appended cycles in which fresh or frozen embryos were transferred until a live birth occurred or until all embryos were used. The latter was considered as the primary outcome. A multivariate regression model was developed to identify prognostic factors for CLBR and test the impact of the patient's PCOS phenotype. MAIN RESULTS AND THE ROLE OF CHANCE Half of the patients presented with a hyperandrogenic PCOS phenotype (n = 140 A/HOP and n = 20 C/HP vs. n = 160 D/OP). BMI was significantly different between phenotype groups (27.4 ± 5.4 kg/m2 for A/HOP, 27.1 ± 5.4 kg/m2 for C/HP and 23.3 ± 4.4 kg/m2 for D/OP, P < 0.001). Metformin was used in 33.6% of patients with PCOS phenotype A/HOP, in 15.0% of C/HP patients and in 11.2% of D/OP patients (P < 0.001). Anti-müllerian hormone levels differed significantly between groups: 12.4 ± 8.3 µg/l in A/HOP, 7.7 ± 3.1 µg/l in C/HP and 10.4 ± 5.9 µg/l in D/OP patients (P = 0.01). The number of cumulus-oocyte complexes (COC) was significantly different between phenotype groups: 25.9 ± 19.1 COC in patients with phenotype A/HOP, 18.3 ± 9.0 COC in C/HP and 19.8 ± 13.5 COC in D/OP (P = 0.004). After IVM, patients with different phenotypes also had a significantly different number of mature oocytes (12.4 ± 9.3 for A/HOP vs. 6.5 ± 4.2 for C/HP vs. 9.1 ± 6.9 for D/OP, P < 0.001). The fertilisation rate, the number of usable embryos and the number of cycles with no embryo available for transfer were comparable between the three groups. Following the first embryo transfer, the positive hCG rate and LBR were comparable between the patient groups (44.7% (55/123) for A/HOP, 40.0% (6/15) for C/HP, 36.7% (47/128) for D/OP, P = 0.56 and 25.2% (31/123) for A/HOP, 6.2% (1/15) for C/HP, 26.6% (34/128) for D/OP, respectively, P = 0.22). However, the incidence of early pregnancy loss was significantly different across phenotype groups (19.5% (24/123) for A/HOP, 26.7% (4/15) for C/HP and 10.2% (13/128) for D/OP, P = 0.04). The CLBR was not significantly different following univariate analysis (40.0% (56/140) for A/HOP, 15% (3/20) for C/HP and 33.1% (53/160) for D/OP (P = 0.07)). When a multivariable logistic regression model was developed to account for confounding factors, the PCOS phenotype appeared to be significantly correlated with CLBR, with a more favourable CLBR in the A/HOP subgroup (OR 0.26 for phenotype C/HP (CI 0.06-1.05) and OR 0.47 for phenotype D/OP (CI 0.25-0.88), P = 0.03)). LIMITATIONS, REASONS FOR CAUTION These data should be interpreted with caution as the retrospective nature of the study holds the possibility of unmeasured confounding factors and misassignment of the PCOS phenotype. Moreover, the sample size for phenotype C/HP was too small to draw conclusions for this subgroup of patients. WIDER IMPLICATIONS OF THE FINDINGS Caucasian infertile patients with a PCOS phenotype A/HOP who undergo IVM achieved a higher CLBR than their counterparts with C/HP and D/OP. This is in strong contrast with previously reported outcomes following OS where women with PCOS and hyperandrogenism (A/HOP and C/HP) performed significantly worse. For PCOS patients who require ART, the strategy of OS followed by an elective freeze-all strategy remains to be compared with IVM in a prospective fashion; however, the current data provide support for IVM as a valid treatment option, especially in the most severe PCOS phenotypes (A/HOP). Our data suggest that proper patient selection is of utmost importance in an IVM programme. STUDY FUNDING/COMPETING INTEREST(S) The clinical IVM research has been supported by research grants from Cook Medical and Besins Healthcare. All authors declared no conflict of interest.

Abstract
STUDY QUESTION Is maternal polycystic ovary syndrome (PCOS) associated with increased offspring risk of congenital heart defects? SUMMARY ANSWER This study does not support a strong association between PCOS and an increased risk of congenital heart defects. WHAT IS KNOWN ALREADY In addition to affecting reproductive health, PCOS may involve insulin resistance. Maternal pregestational diabetes is associated with an increased risk of congenital heart defects and therefore PCOS may increase the risk of congenital heart defects in the offspring. STUDY DESIGN, SIZE, DURATION In this nationwide cohort study, we used data from Danish health registers collected from 1995 to 2018. The study included 1 302 648 offspring and their mothers. PARTICIPANTS/MATERIALS, SETTING, METHODS Participants were live singleton offspring born during the study period. Information on maternal PCOS and offspring congenital heart defects was obtained from the National Patient Register. Logistic regression analysis was used to compute prevalence (odds) ratio (PR) of the association between PCOS and offspring congenital heart defects. MAIN RESULTS AND THE ROLE OF CHANCE Among 1 302 648 live-born singletons, 11 804 had a mother with PCOS. Of these, 143 offspring had a congenital heart defect (prevalence 121 per 10 000) as compared with 12 832 among mothers without PCOS (prevalence 99 per 10 000). The adjusted PR was 1.22, 95% CI 1.03-1.44 comparing prevalence of congenital heart defects in offspring of women with PCOS with offspring of women without. After adjusting for the potentially mediating effect of pregestational diabetes, the PR was 1.16, 95% CI 0.98-1.37. LIMITATIONS, REASONS FOR CAUTION PCOS may be underdetected in the National Patient Register. However, we expect that the mothers that we identified with PCOS truly had PCOS, thus, the estimated associations are not likely to be affected by this misclassification. The study does not provide evidence to rule out a moderate or weak association. WIDER IMPLICATIONS OF THE FINDINGS These findings provide reassurance to clinicians counselling pregnant women with PCOS that the disease does not pose a markedly increased risk of offspring congenital heart defects. STUDY FUNDING/COMPETING INTEREST(S) The study was funded by the Novo Nordisk Foundation. M.L. reports personal fees from Dansk Lægemiddel Information A/S outside the submitted work. The remaining authors have no conflicts of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
Polycystic ovarian syndrome (PCOS) is the most common endocrinological disease of reproductive-aged women, with an estimated incidence ranging from 5% to 15%. The clinical manifestations of PCOS are heterogeneous and vary according to the age of the patient. Insulin resistance (IR), hyperandrogenism, and obesity are widely assumed to play a pivotal role in the pathophysiological mechanism of PCOS. As previously stated by many conducted meta-analyses, PCOS can cause a rising risk of pregnancy complications, including maternal, fetal, and neonatal complications. Pregnancy-induced hypertension (PIH), preeclampsia (PE), gestational diabetes mellitus (GDM), spontaneous preterm birth (PTB), and an increased necessity for a cesarean section (CS) are the most documented maternal implications. Regarding fetal outcomes, PCOS has also been correlated with elevated neonatal morbidity, prematurity, fetal growth restriction (FGR), birth weight variations (large for gestational age (LGA) and small for gestational age (SGA), and transfer to the neonatal intensive care unit (NICU). Owing to the variability of the studies performed, the association of PCOS with an elevated risk of adverse pregnancy outcomes is still controversial. This variability is found in the diagnosis and clinical presentations of PCOS, and can be influenced by pre-pregnancy circumstances and therapies as well as particular population and environmental features. The Amsterdam consensus guidelines confirm that obesity and IR can worsen maternal and fetal complications; thus, a closer follow-up should be offered to PCOS women during pregnancy.

Abstract
INTRODUCTION This review covers the current evidence regarding the use of metformin as a therapeutic intervention for optimizing pregnancy outcomes in women with polycystic ovary syndrome (PCOS). AREAS COVERED After searching Medline, Embase and CINAHL, all important large clinical trials and observational studies plus systematic reviews, meta-analyses and Cochrane reviews have been summarized here. The results have been compared to culminate in a thorough review and discussion on the use of metformin in relation to reproductive outcomes for women with PCOS. The role of metformin in PCOS is explored both in terms of achieving conception and during pregnancy. The existing evidence around metformin use is summarized both during the preconceptual period and during pregnancy, in relation to reproductive outcomes. EXPERT OPINION Metformin is a widely used medication, often prescribed to improve reproductive outcomes for women with PCOS. However, the evidence remains equivocal regarding its efficacy both in optimizing fertility and pregnancy outcomes. More research is required with special emphasis on metformin use within different populations, including ethnic groups and women with varying BMI ranges.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy among reproductive age women and is associated with subfertility and adverse perinatal outcomes, which may include early pregnancy loss, gestational diabetes mellitus, hypertensive spectrum disorder, preterm birth, fetal growth disorders, and cesarean deliveries. The phenotypic heterogeneity, different diagnostic criteria, and PCOS-related conditions that women enter pregnancy with have limited evidenced-based studies and guidelines to reduce pregnancy complications among this high-risk population. This review summarizes the available evidence on the approach and management of women with PCOS preconception, prenatal, and postpartum.

Abstract
OBJECTIVE To investigate the placental morphology alterations and identify the clinical characteristics of women with polycystic ovary syndrome (PCOS) and their newborns. Pregnant women with PCOS (n = 12) and pregnant women without PCOS (n = 11) were recruited. Then, the placenta, maternal blood and cord blood were collected after delivery. DESIGN Clinical observational study. SETTING Not applicable. PATIENT(S) In the present study, pregnant women with PCOS and healthy pregnant women were recruited from the clinic of the Department of Obstetrics and Gynecology, First Affiliated Hospital, Heilongjiang University of Chinese Medicine, China, between February 2015 and October 2015. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) A proteomic analysis was performed on the placenta in women with PCOS and healthy women. RESULT(S) The maternal testosterone, androstenedione, dehydroepiandrosterone sulfate, free androgen index, cholesterol, apolipoprotein B, and apolipoprotein B/apolipoprotein A-I levels were significantly higher in the PCOS group than in the control group, and the offspring in the PCOS group had higher dehydroepiandrosterone sulfate, high-density lipoprotein, and cholesterol levels, when compared with the control group. The placenta in the PCOS group demonstrated infarction, calcification, and a greater intervillous space, when compared with the control group. A higher level of estrogen receptor-β protein was observed in the placenta of women with PCOS, when compared with women without PCOS. A total of 258 proteins in the placenta were identified to be significantly different, when the PCOS and control groups were compared, and fibronectin 1 exhibited the closest relationship with other differential proteins. CONCLUSION(S) The overexposure to hyperandrogenism and hyperlipidemia affects the functions of the placenta, which are associated with the development of metabolic disorders in newborns.

Abstract
The beneficial effects of metformin, especially its capacity to ameliorate insulin resistance (IR) in polycystic ovary syndrome (PCOS), explains why it is widely prescribed. However, its effect on the offspring of patients with PCOS remains uncertain. This study investigated the impact of metformin treatment on the first- and second-generation female offspring born to letrozole-induced PCOS-IR rats. Forty-five female Wistar rats were implanted with continuous-release letrozole pellets or placebo and treated with metformin or vehicle control. Rats exposed to letrozole showed PCOS-like reproductive, endocrine, and metabolic phenotypes in contrast to the controls. Metformin significantly decreased the risk of body weight gain and increased INSR expression in F1 female offspring in PCOS-IR rats, contributing to the improvement in obesity, hyperinsulinemia, and IR. Decreased FSHR expression and increased LHCGR expression were observed in F1 female rats of the PCOS-IR and PCOS-IR+Metformin groups, suggesting that FSHR and LHCGR dysfunction might promote the development of PCOS. Nevertheless, we found no significant differences in INSR, FSHR, and LHCGR expression or other PCOS phenotypes in F2 female offspring of PCOS-IR rats. These findings indicated widespread reproductive, endocrine, and metabolic changes in the PCOS-IR rat model, but the PCOS phenotypes could not be stably inherited by the next generations. Metformin might have contributed to the improvement in obesity, hyperinsulinemia, and IR in F1 female offspring. The results of this study could be used as a theoretical basis in support of using metformin in the treatment of PCOS-IR patients.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS), a common endocrine-metabolic dysfunction in reproductive-aged women, may be involved in compromised pregnancy and offspring outcomes. This study aimed to investigate whether maternal PCOS affects fetal growth, fetal development, and placental features. METHODS This retrospective case-control study included 60 pregnant women with PCOS (PCOS group) and 120 healthy pregnant women without PCOS (control group). Fetal magnetic resonance imaging (MRI) was performed followed by an ultrasound examination and indications for imaging, including known or suspected fetal pathology, history of fetal abnormality in previous pregnancy or in a family member, and concern for placenta accreta. Fetal MRI images were analyzed for head circumference (HC), abdomen circumference (AC), lung-to-liver signal intensity ratio (LLSIR, a prenatal marker of fetal lung maturity), lengths of liver and kidney diameters in fetuses, and placental relative signal intensity on T2-weighted single-shot fast spin echo (SSFSE) imaging (rSISSFSE), and placental relative apparent diffusion coefficient value (rADC). Data on height and weight of offspring were collected through telephone follow-up. RESULTS Compared to the control group, the PCOS group showed the following characteristics: (1) smaller biparietal diameter and femur length in fetuses (P=0.026 and P=0.005, respectively), (2) smaller HC in fetuses (evident after 32 weeks; P=0.044), (3) lower LLSIR and smaller dorsoventral length of liver in fetuses (evident before 32 weeks; P=0.005 and P=0.019, respectively), and (4) smaller placental thickness (evident before 32 weeks; P=0.017). No significant differences in placental rSISSFSE or rADC were observed between the groups (all P>0.05). No significant differences in height and weight of offspring during childhood existed between the groups (all P>0.05). CONCLUSIONS There exist alterations of fetal growth, fetal development, and placental features from women with PCOS.

Abstract
BACKGROUND/PURPOSE Pregnant women with polycystic ovary syndrome seem to be prone for adverse maternal and perinatal outcomes, but there is no conclusive evidence. Indian data evaluating the pregnancy outcome in women with polycystic ovary syndrome are sparse. This study was proposed to evaluate the pregnancy outcome in women with polycystic ovary syndrome. METHODS This descriptive study on 135 pregnant women with polycystic ovary syndrome was carried out in a tertiary care hospital in South India from January 2016 to October 2017. Data regarding present pregnancy, polycystic ovary syndrome and maternal/ perinatal outcomes were analysed using SPSS version 20. Categorical variables studied were parity, various maternal and perinatal outcomes. RESULTS The mean age was 26.8 years, 77% had high BMI, and 88% had history of primary infertility. The mean age was 26.8 years, 77% had high BMI, and 88% had history of primary infertility. The proportion of hypertensive disorders of pregnancy was (17.8%), PROM (18.5%), low APGAR score at 5 min (13%), gestational diabetes (13%), miscarriage (2.2%), preterm delivery (10.4%), caesarean delivery (30.4%), low birth weight babies (2%), macrosomia (0.7%), PPROM (8%), perinatal mortality (2%) and NICU admission (20%). CONCLUSION The proportion of hypertensive disorders of pregnancy, PROM, low birth weight babies, low APGAR score at 5 min was found to be higher, but the proportion of GDM, miscarriage, preterm delivery, meconium stained liquor, caesarean delivery, small for gestational age/IUGR, macrosomia, PPROM, perinatal mortality, NICU admission and congenital anomalies was found to be either similar or lower in pregnant women with PCOS in our study to those described in the general pregnant population.

Abstract
An increase in cholesterol levels is perceived during pregnancy and is considered as a normal adaptive response to the development of the fetus. In some pregnancies, excessive increase in total cholesterol with high levels of Low-Density Lipoprotein leads to maladaptation by the fetus to cholesterol demands, resulting in a pathological condition termed as maternal hypercholesterolemia (MH). MH is considered clinically irrelevant and therefore cholesterol levels are not routinely checked during pregnancy, as a consequence of which there is scarce information on its global prevalence in pregnant women. Studies have reported that MH during pregnancy can cause atherogenesis in adults emphasizing the concept of in utero programming of fetus. Moreover, Gestational Diabetes Mellitus, obesity and Polycystic Ovary Syndrome are potential risk factors which strengthen combined pathologies in placenta and fetuses of mothers with MH. However, lack of conclusive evidence on cholesterol transport and underlying programming demand substantial research to develop population-based life style strategies for women in their childbearing years. The current review focuses on the mechanisms and outcomes of MH from existing epidemiological as well as experimental data and presents a detailed insight on this novel risk factor of cardiovascular diseases.

Abstract
STUDY QUESTION Are higher testosterone levels during pregnancy in women with polycystic ovary syndrome (PCOS) associated with longer offspring anogenital distance (AGD)? SUMMARY ANSWER AGD was similar in 3-month-old children born of mothers with PCOS compared to controls. WHAT IS KNOWN ALREADY AGD is considered a marker of prenatal androgenization. STUDY DESIGN, SIZE, DURATION Maternal testosterone levels were measured by mass spectrometry at Gestational Week 28 in 1127 women. Maternal diagnosis of PCOS before pregnancy was defined according to Rotterdam criteria. Offspring measures included AGD from anus to posterior fourchette (AGDaf) and clitoris (AGDac) in girls and to scrotum (AGDas) and penis (AGDap) and penile width in boys and body composition (weight and BMI SD scores) at age 3 months. PARTICIPANTS/MATERIALS, SETTING, METHODS The study was part of the prospective study, Odense Child Cohort (OCC), and included mothers with PCOS (n = 139) and controls (n = 1422). The control population included women with regular menstrual cycles (<35 days) before conception and no signs of androgen excess (hirsutism and/or acne). MAIN RESULTS AND THE ROLE OF CHANCE AGD measures were comparable in offspring of women with PCOS compared to controls (all P > 0.2) despite significantly higher maternal levels of total testosterone (mean: 2.4 versus 2.0 nmol/l) and free testosterone (mean: 0.005 versus 0.004 nmol/l) in women with PCOS versus controls (both P < 0.001). In women with PCOS, maternal testosterone was an independent positive predictor of offspring AGDas and AGDap in boys. Maternal testosterone levels did not predict AGD in girls born of mothers with PCOS or in boys or girls born of women in the control group. LIMITATIONS, REASONS FOR CAUTION The diagnosis of PCOS was based on retrospective information and questionnaires during pregnancy. Women participating in OCC were more ethnically homogenous, leaner, more educated and less likely to smoke compared to the background population. Our study findings, therefore, need to be reproduced in prospective study cohorts with PCOS, in more obese study populations and in women of other ethnicities. WIDER IMPLICATIONS OF THE FINDINGS Our finding of the same AGD in girls born of mothers with PCOS compared to controls expands previous results of studies reporting longer AGD in adult women with PCOS. Our results suggest that longer AGD in adult women with PCOS could be the result of increased testosterone levels in puberty, perhaps in combination with weight gain. STUDY FUNDING/COMPETING INTEREST(S) Financial grants for the study were provided by the Danish Foundation for Scientific Innovation and Technology (09-067180), Ronald McDonald Children Foundation, Odense University Hospital, the Region of Southern Denmark, the Municipality of Odense, the Mental Health Service of the Region of Southern Denmark, The Danish Council for Strategic Research, Program Commission on Health, Food and Welfare (2101-08-0058), Odense Patient data Explorative Network, Novo Nordisk Foundation (grant no.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) and polycystic ovarian syndrome (PCOS) have been associated with adverse maternal and neonatal outcomes, but the evidence on the impact of coexistent PCOS and GDM is rather limited and inconclusive. We investigated the impact of comorbid PCOS on pregnancy outcomes among women with GDM. METHODS This retrospective cohort study included women diagnosed with GDM on 75 g oral glucose tolerance test on routine antenatal screening tests at Liverpool Hospital between February 2015 and January 2019. Women were then grouped into those with and without PCOS based on the Rotterdam criteria. The demographic details, clinical data and pregnancy outcomes were compared between the two groups. RESULTS Among the 1545 women with GDM included in the study, there were 326 women with PCOS. Women with GDM and PCOS (GDM+PCOS+) were younger (29.5 years vs 31.5 years, p < 0.001), more likely to be primigravidae (31.9% vs 20%, p < 0.001), as well as of Caucasian descent (37.4% vs 21.7%, p < 0.001). PCOS was an independent risk factor for the development of preeclampsia on regression analysis (OR 2.06, p = 0.021). Women with PCOS and GDM had a higher body mass index (31.5 kg/m2 vs 27.7 kg/m2, p < 0.001), significant gestational weight gain (12.6 kg vs 11.5 kg, p = 0.016), and more frequent use of pharmacotherapies to manage their GDM (57.7% vs 45.2%, p < 0.001). There was no statistically significant difference in the rates of adverse neonatal outcomes in both the groups. CONCLUSION Among women with GDM, PCOS was an independent risk factor for the development of preeclampsia and significant gestational weight gain, warranting vigilant monitoring of blood pressure, blood glucose levels and body weight, and implementing timely interventions to improve obstetric and neonatal outcomes.

MAIN OUTCOME MEASURE(S) Maternal report of offspring ADHD, anxiety, or conduct disorder diagnosis at 7 to 8 years; emotional symptoms, behavioral problems (including peer relationship, conduct, hyperactivity/inattention), and prosocial problems measured with the Strengths and Difficulties Questionnaire (SDQ) at 7 years. RESULT(S) Prevalence of PCOS and hirsutism were 12.0% and 3.9%; 84% of women with hirsutism had PCOS. After adjustment for sociodemographic covariates, prepregnancy body mass index, and parental history of affective disorders, children born to mothers with PCOS had higher risk of anxiety (adjusted risk ratio [aRR] 1.62; 95% confidence interval [CI], 1.02-2.57) and borderline emotional symptoms (aRR 1.66; 95% CI, 1.18-2.33) compared with children born to mothers without PCOS. The associations between maternal PCOS and offspring ADHD were positive but imprecise. Maternal hirsutism was related to a higher risk of children's ADHD (aRR 2.33; 95% CI, 1.28-4.24), conduct disorder (aRR 2.54; 95% CI 1.18-5.47), borderline emotional symptoms, peer relationship problems, and conduct problems (aRRs 2.61; 95% CI, 1.69-4.05; 1.92; 95% CI, 1.16-3.17; and 2.22; 95% CI, 1.30-3.79, respectively). CONCLUSION(S) Maternal PCOS was associated with offspring anxiety, and hirsutism was related to other offspring behavioral problems. These findings should be interpreted with caution as replication is needed in prospective cohort studies that assess PCOS and hirsutism diagnoses using medical records.

Abstract
Hyperandrogenism is considered 1 of the most important characteristics of polycystic ovary syndrome, which affects more than 10% of females of reproductive age and is a common cause of infertility. In addition to the effects on patients themselves, maternal androgen excess has also been reported to impair the growth and development of offspring. In our current study, we found that maternal testosterone (T) treatment during different gestational stages increased the percentage of atretic follicle and decreased corpus luteum formation in female offspring. In addition, decreased serum estradiol and increased T levels were also observed in female offspring of T-treated mice during late gestational stage. Further studies revealed that Forkhead box protein L2 (FOXL2) and Cytochrome P450 family 19 subfamily a member 1 (CYP19A1) expression in granulosa cells of these female offspring mice were decreased. By using mouse primary granulosa cells and the KGN cell line, we demonstrated that decreasing FOXL2 and CYP19A1 levels in ovarian granulosa cells partially may contribute to disturbed sex hormone synthesis in female offspring of T-treated mice during the late gestational stage. Findings from our current study highlight a critical role of excess maternal T exposure, especially during the late gestational stage, which could further lead to aberrant ovary development and sex hormone synthesis in female offspring.

Growth and other health outcomes of 2-year-old singletons born after IVM versus controlled ovarian stimulation in mothers with polycystic ovary syndrome. Hum Reprod Open 2020; 2020:hoz043.

Abstract
STUDY QUESTION Does In vitro maturation (IVM) of immature oocytes affect health, including growth at 2 years of age, in singletons born to mothers with polycystic ovary syndrome (PCOS)? SUMMARY ANSWER This study of 92 singletons born after IVM in mothers with PCOS showed no significant differences in anthropometry and health outcome parameters in comparison with a cohort of 74 peers born after intracytoplasmic sperm injection (ICSI) and conventional controlled ovarian stimulation (COS) in mothers with PCOS. WHAT IS KNOWN ALREADY IVM has been used worldwide in women with PCOS. However, the paucity of available data related to children's health following IVM is an important impediment to a more widespread use of the technology. Although previous reports on the neonatal outcome after IVM are generally reassuring, these studies have flaws that hamper the interpretation of outcomes. Moreover, few studies have reported on health outcomes after IVM beyond infancy, and particularly growth data in children born after IVM of immature oocytes from mothers with PCOS are lacking. STUDY DESIGN SIZE DURATION This single-center cohort study compared anthropometry and health outcomes in 92 singletons born after ICSI of in vitro matured oocytes with 74 singletons born after ICSI without IVM (COS). All participants were born to mothers who were diagnosed with PCOS phenotype A, B, C or D and reached the age of 2 years between November 2012 and June 2019. Singletons born after COS were randomly selected for follow-up until young adulthood. PARTICIPANTS/MATERIALS SETTING METHODS Anthropometric parameters and health status data were prospectively collected at birth, 4 months and 2 years in cohorts of singletons followed since birth. Results were adjusted for neonatal (birthweight z-score, birth order), treatment (day of transfer, number of embryos transferred, mode of transfer) and parental (maternal smoking, age, body mass index (BMI), anti-Müllerian hormone level, PCOS phenotype, gestational diabetes, hypertensive disorder and paternal BMI) characteristics. MAIN RESULTS AND THE ROLE OF CHANCE Overall, no differences were found for bodyweight, height and head circumference z-score between IVM and COS children at birth, at 4 months or at 2 years (all P > 0.05). In addition, z-scores of waist and mid-upper arm circumference at 2 years were comparable in IVM and COS children. Adjustment for covariates did not change the conclusion. Surgical intervention rate as well as the hospital admission rate were comparable between the IVM and COS group (all P > 0.05). The proportion of children born to mothers with metabolically unfavorable PCOS phenotypes (A and C) was comparable in the two groups (52.1% in IVM and 45.9% in COS). Mothers giving birth to a child conceived using IVM were younger than mothers in the COS group but their BMI was comparable. LIMITATIONS REASONS FOR CAUTION Although our study describes the largest cohort to date of singletons born after IVM applied in mothers with well-defined PCOS phenotypes, the current sample size only allowed us to detect moderate differences in anthropometry. Also, follow-up of children born after IVM for indications other than PCOS, for example fertililty preservation after cancer diagnosis, is highly recommended. WIDER IMPLICATIONS OF THE FINDINGS We did not observe adverse effects of IVM on growth parameters in offspring ~2 years of age compared to COS, but future studies should focus on cardiovascular and metabolic outcomes in these children and adolescents given their mother's PCOS condition.

Abstract
Dietary intake potentially modifies the prevalence or severity of asthma. The prevalence of asthma is higher in women with polycystic ovary syndrome (PCOS); it is not known if diet confounds or modifies the association between asthma and PCOS. The aims of this study were: (i) To determine if the association of PCOS and asthma is independent of dietary pattern and (ii) to determine if dietary pattern modifies the association between PCOS and asthma. Women in this study were from the Australian Longitudinal Study on Women's Health (ALSWH) cohort born between 1973 to 1978 and aged 18 to 23 years (n = 7382). Logistic regression was used to assess the association between PCOS and asthma, adjusting for the following: (i) Potential confounders identified a priori and (ii) dietary patterns (z-score) identified by principle component analysis. In the adjusted analysis, women with PCOS were more likely to have asthma than the women without PCOS (OR 1.35 and 95% CI, 1.02 and 1.78). This relationship was not altered by further adjustment for dietary patterns (non-core food, meats and takeaway, or Mediterranean-style pattern). In the interaction analysis, only the women consuming less than the median intake of non-core foods (i.e., lower intake of discretionary or unhealthy foods) and with PCOS were more likely to have asthma (OR 1.91 and 95% CI, 1.29 and 2.82). Dietary intake did not confound the relationship between PCOS and asthma. Other mechanistic pathways are likely responsible for the asthma and PCOS association, and further studies assessing factors such as oral contraceptive use and sex steroid hormones warrant investigation.

Abstract
Polycystic ovary syndrome (PCOS), characterized by hormonal imbalance and ovarian dysfunction, often starts during adolescence. Inconsistent diagnostic criteria, variable provider knowledge, and lack of consensus pose specific challenges for the care of women with PCOS. These factors encourage inaccurate diagnosis with both under and overdiagnosis. This unfavorable diagnostic experience exasperates affected women and limits timely opportunities for intervention to minimize associated comorbidities, especially during the transition from pediatric to adult care. Recognition of these issues in the care of adolescents and women with PCOS inspired the development of the International Evidence-Based PCOS Guidelines, which emphasize the prevention, screening, and treatment of PCOS across the reproductive lifespan. The Guidelines and accompanying meta-analyses focus on three major categories of associated comorbidities: (1) reproductive; (2) metabolic; and (3) psychological. With the exception of infertility, this article considers common manifestations and comorbidities associated with PCOS throughout the lifecycle. Healthy lifestyle interventions with prevention of excess weight gain comprise the primary intervention for all comorbidities. Hence, early identification of girls "at risk" for PCOS and those with PCOS is a priority. Extensive guidelines for provider and patient education aim to decrease the medical, psychosocial, and economic burdens attributable to PCOS and its associated comorbidities.

Abstract
Background Intestinal dysbiosis, or dysbacteriosis, is an abnormal interaction between the intestinal microbiota and the host cells due to altered microbial diversity. This study aimed to investigate the metabolic effects and changes in the intestinal microbiota in newborn rats following exposure to increased levels of maternal androgens in a rat model of maternal polycystic ovary syndrome (PCOS). Material/Methods The administration of androgen developed the rat maternal PCOS model during pregnancy. Maternal rat ovarian follicles were counting and assessed by histology. The metabolic phenotype of newborn rats was evaluated and included an insulin tolerance test, a glucose tolerance test, and measurement of serum levels of triglyceride, insulin, cholesterol, adiponectin, and leptin. Expression of pro-inflammatory cytokines was detected using quantitative reverse transcription-polymerase chain reaction (qRT-PCR), serum levels were measured by enzyme-linked immunosorbent assay (ELISA), and proteins associated with adipose tissue remodeling and adipocyte differentiation were measured by Western blot. Results Markers of systemic inflammation were significantly increased in the female offspring but not in the male offspring born to rat in the PCOS model. Following birth, newborn rats that received antibiotics showed an improved metabolic phenotype, with reduced serum lipid levels, insulin resistance, body weight, inflammation of adipose tissue, and serum levels of inflammatory cytokines compared with controls. Probiotics had no significant effects on these parameters in newborn rats. Conclusions In a rat model of maternal PCOS, exposure to androgens in utero resulted in dysbiosis of the intestinal microbiota and metabolic disorders of the newborn female rats.

Abstract
There is evidence showing a positive correlation between prenatal androgens and their effect on the development of central nervous system and the autistic spectrum disorder (ASD) phenotype in offspring of mothers with polycystic ovary syndrome (PCOS). We applied a systematic review to investigate whether women with PCOS have increased odds of having a child with ASD, while, secondarily, if these women themselves are at high risk of having the disease. Major databases from inception until 14th October 2018 were searched. The primary outcome measure was the odds of an ASD diagnosis in children of mothers with diagnosed PCOS, while the secondary outcome was the odds of ASD diagnosis in women with PCOS. Scheduled subgroup analyses were according to the time of birth and maternal age. We assessed the odds ratio (OR), using a random-effects model; heterogeneity was assessed by I2 and τ2 statistics. The quality of the evidence was evaluated using the Newcastle-Ottawa Scale. Ten studies were eligible for inclusion, including a total of 33,887 ASD children and 321,661 non-ASD children. Diagnosed PCOS was associated with a 1.66 times increase in the odds of ASD in the offspring [95% CI: 1.51, 1.83, p = 1.99 × 10-25, 7 studies, I2 = 0%, τ2 = 0]. Women with PCOS were 1.78 times more likely to be diagnosed with ASD (95% CI: 1.10, 2.87, p = 0.0179, 5 studies, I2 = 85.4%, τ2 = 0.2432). Additional analyses did not change the initial result. The overall quality of the evidence was high. The pooled effects size displayed low heterogeneity (I2 = 0%) for the primary outcome. While the heterogeneity in the secondary outcome appears to attenuate when only high quality studies are synthesized, still the result exhibits significant heterogeneity. Τhe available data allowed a subgroup analysis only for classification system for PCOS diagnosis and showed a significant increase of ASD diagnosis in the offspring of women with Read Code and ICD diagnosed PCOS. In conclusion, the available evidence suggests that women with PCOS have increased odds of having a child with ASD, an effect size estimate based on a large number of patients from studies of good quality. Regarding the evidence on the prevalence of ASD in PCOS women, results suggest that women with PCOS are more likely to be diagnosed with ASD.

Abstract
Background Recent registry studies have demonstrated a higher prevalence of asthma among women with polycystic ovary syndrome (PCOS). We aimed to assess the association and heritability of PCOS and asthma in a Danish twin cohort. Methods Data for 32 382 female twins from the Danish Twin Registry were included. Twins with PCOS were identified by searching the Danish National Patient Registry for International Classification of Diseases-10 code E28.2. Asthma was diagnosed by questionnaires. Results 103 (0.3%) women had a PCOS diagnosis. The risk of asthma was increased among women with PCOS compared with women without (18% versus 9%, respectively; OR 2.11 (95% CI 1.13-3.96); p=0.02). After adjustment for age, body mass index, alcohol consumption and smoking status, the risk of asthma was still increased, but was no longer statistically significant (OR 1.54 (95% CI 0.75-3.17); p=0.24). Variance components analysis showed that shared environmental factors explained 49% (95% CI 24-68%) and unique environmental factors explained 51% (95% CI 32-76%) of the susceptibility to PCOS. For asthma, 44% (95% CI 28-61%) of the variance was explained by genetic factors, whereas 25% (95% CI 11-38%) was ascribable to shared environmental factors and 31% (95% CI 26-36%) to unique environmental factors. Conclusion The risk of asthma is twice as high among female twins with PCOS. The individual susceptibility to PCOS is mainly due to environmental factors and not genetics.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine condition in reproductive-age women. By comprising reproductive, endocrine, metabolic and psychological features—the cause of PCOS is still unknown. Consequently, there is no cure, and management is persistently suboptimal as it depends on the ad hoc management of symptoms only. Recently it has been revealed that androgens have an important role in regulating female fertility. Androgen actions are facilitated via the androgen receptor (AR) and transgenic Ar knockout mouse models have established that AR-mediated androgen actions have a part in regulating female fertility and ovarian function. Considerable evidence from human and animal studies currently reinforces the hypothesis that androgens in excess, working via the AR, play a key role in the origins of polycystic ovary syndrome (PCOS). Identifying and confirming the locations of AR-mediated actions and the molecular mechanisms involved in the development of PCOS is critical to provide the knowledge required for the future development of innovative, mechanism-based interventions for the treatment of PCOS. This review summarises fundamental scientific discoveries that have improved our knowledge of androgen actions in PCOS etiology and how this may form the future development of effective methods to reduce symptoms in patients with PCOS.

Abstract
Women with polycystic ovary syndrome (PCOS) have unfavorable metabolic profiles. Their offspring may be affected by such risks. The objective of the current study was to disclose associations between preconception health of these women and health of their offspring. 74 women diagnosed with PCOS according to the Rotterdam criteria were screened systematically before conception. Cardiovascular health of their offspring was assessed at 2.5-4 (n = 42) or at 6-8 years of age (n = 32). Multivariate linear regression analysis was performed with adjustments for potential confounders. In the primary analyses the association between preconception Body Mass index (BMI) and offspring BMI was evaluated. Secondly associations between preconception blood pressure, androgens, insulin-resistance (HOMA-IR), and LDL-cholesterol in women with PCOS and BMI and blood pressure of offspring were assessed. Results show that preconception BMI of women with PCOS was positively associated with sex- and age-adjusted BMI of their offspring at 6-8 years of age (β = 0.55 (95% CI: 0.12 to 0.97), p = .012). No other significant associations were found. In conclusion, our data suggest that preconception BMI in PCOS is significantly associated with offspring BMI at 6-8 year of age. If this suggestion could be confirmed this may provide an opportunity for improving the future health of these children.
