Abstract
INTRODUCTION A great deal of literature has recently evaluated the prevention and management of ovarian hyperstimulation syndrome (OHSS) in the outpatient setting, but there remains a dearth of research evaluating OHSS in the emergency department (ED) and its management. OBJECTIVE This narrative review evaluates the underlying pathophysiology and clinical manifestations of OHSS and discusses approaches to patient care in the ED based on current literature. DISCUSSION OHSS is an iatrogenic complication caused by an excessive response to controlled ovarian stimulation during assisted reproductive cycles (ART). OHSS complicates up to 30% of ART cycles, and many of these patients seek initial care in the ED. Risk factors for the development of OHSS include age < 35, history of polycystic ovarian syndrome or previous OHSS, and pregnancy. Emergency physicians will be faced with several complications including ascites, abdominal compartment syndrome, renal dysfunction, acute respiratory distress syndrome, thromboembolic disease, and hemodynamic instability. Critical patients should be evaluated in the resuscitation bay, and consultation with the primary obstetrics/gynecology team is needed, which improves patient outcomes. This review provides several guiding principles for management of OHSS and associated complications. CONCLUSIONS OHSS occurs in up to 30% of IVF cycles and carries a high morbidity. Effective care of the OHSS patient begins with early diagnosis while evaluating for other diseases and complications. Understanding these complications and an approach to the management of OHSS is essential to optimizing patient care.

Assisted reproductive technology and the risk of preeclampsia: an updated systematic review and meta-analysis. BMC Pregnancy Childbirth 2019; 19:149. [PMID: 31046710 PMCID: PMC6498659 DOI: 10.1186/s12884-019-2291-x] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2018] [Accepted: 04/12/2019] [Indexed: 11/22/2022] Open
Abstract
Background The objective of this systematic review and meta-analyses was to assess the risk of preeclampsia among women who conceived with assisted reproductive technology (ART). Methods We searched the ISI Web of Knowledge, Medline/PubMed, Scopus, and Embase (from inception to May 2017) for English language articles using a list of key words. In addition, reference lists from identified studies and relevant review articles were also searched. Data extraction was performed by two authors, and the study quality was assessed using the Newcastle–Ottawa Scale. Random-effects model meta-analysis was applied to pool the relative risks (RR) across studies. Results A total of 48 studies (5 case-control studies and 43 cohort studies) were included in this meta-analysis. The Cochran Q test and I2 statistics revealed substantial heterogeneity (Q = 26,313.92, d.f. = 47, p < 0.001 and I2 = 99.8%). Meta-analysis showed a significant increase in preeclampsia in women who conceived by ART compared with those who conceived spontaneously (RR = 1.71, 95% CI = 1.11–2.62, p = 0.015). Conclusions The findings of this systematic review indicate that the use of ART treatment is associated with a 1.71-fold increase in preeclampsia.

Abstract
Objective: To evaluate the elements more likely to be associated with premature rupture of membrane (PROM) in patients that use assisted reproductive technology (ART).Materials and methods: A retrospective case-control study was performed from January 2014 to August 2017. We included 301 patients, 257 patients were without PROM in the non-PROM group and 44 patients with PROM in the PROM group.Results: In the PROM group, the rate of intracytoplasmic sperm injection (ICSI) and BMI were significantly higher than the non-PROM group. Moreover, the rate of preterm birth was significantly higher in the PROM group. When using logistic regression analysis to decrease the impact of confounding factors, it showed that overweight and ICSI were confirmed to be associated with PROM. After matching 1:2 by BMI, the process of controlled ovarian hyperstimulation was all similar in the two groups. What is more, the rate of twin pregnancies was significantly higher in the preterm PROM (PPROM) group compared with the term PROM group and twin pregnancies were associated with preterm birth.Conclusions: ART parameters ICSI may increase the risk of PROM. Single embryo transfer during ART should be supported to decrease the incidence of PPROM and losing weight is essential for patients before embarking on ART.

Abstract
OBJECTIVE Ovarian hyperstimulation syndrome (OHSS) is a major complication of assisted reproductive technologies (ART). Polycystic ovary syndrome (PCOS) is a risk factor for OHSS. The aim of this randomized clinical trial (RCT) was to study the effect of low-dose aspirin (LDA) on the development of OHSS and ART outcomes in PCOS during ART. MATERIALS AND METHODS This double-blinded placebo controlled RCT was performed on 232 PCOS infertile women in their first ART cycles during 2010-2016. LDA and placebo capsules were prepared, packed and specified by code numbers in similar shapes. One package was given to every woman and asked to take one capsule/day since the 21st day of her cycle prior to the gonadotropin stimulation. Gonadotropin releasing hormone agonist long protocol and triggering by human chorionic gonadotropin were used. Development of moderate to severe OHSS and their ART outcomes were documented then the codes were broken and data analyzed. Chi-square and Mann-Whitney U tests were used for the statistical analyses. RESULTS Eighteen cases that did not follow the study design were excluded. 214 cycles remained for the final analyses with 109 cases in LDA and 105 in the placebo group. Rate of the moderate to severe OHSS in LDA group was 34.9% compared to 30.5% in placebo group (P = 0.494). Fertilization rate was 71.8% vs 65.1% (P = <0.001) and the mean number of grade III embryos were 3.28 ± 3.53 vs 1.46 ± 1.42 (P = 0.014) in LDA and placebo groups, respectively. The mean number of the oocytes in different grades, total and frozen embryos also implantation and clinical pregnancy rates were not different between the groups. CONCLUSION Moderate to Severe OHSS was not decreased but fertilization rate and the mean number of poor quality embryos were increased in LDA arm. REGISTRATION NUMBER IRCT 201105216541N1.

Abstract
Objectives: The aim of the study is to compare the effect of very advanced maternal age (≥45 years) on maternal and neonatal outcomes of twin and singleton pregnancies.Materials and methods: This retrospective cohort study included women ≥ 45 years of age who gave birth to twins. Each was randomly matched to two women ≥ 45 years of age who gave birth to singletons within 7 days of the study subject. Data on maternal age, gravidity, parity, background medical information, body mass index at conception, number of fetuses, mode of conception (either spontaneous or assisted reproductive technology [ART]), mode of delivery, and gestational age at delivery were extracted from a real-time computerized database.Results: The data of 75 twin pregnancies of women aged ≥ 45 years were compared with those of 150 singleton pregnancies matched for maternal age. There were significantly more cases of hypertensive complications among the twin pregnancies compared to the singleton pregnancies (41.33 versus 14.00%, respectively, OR = 3.33, 95% CI = 2.26-8.30, p = .000) and more cases of preeclamptic toxemia (29.33 versus 12.00%, respectively, OR = 3.04, 95% CI = 1.51-6.13, p = .001). The duration of twin pregnancies was much shorter compared to singleton pregnancies, with a higher incidence of deliveries prior to 37 weeks' gestation (56.00 versus 8.00%, respectively, OR = 14.64, 95% CI = 6.94-30.85, p = .000), and deliveries prior to 34 weeks' gestation (22.67 versus 2.00%, respectively, OR = 14.36, 95% CI = 4.06-50.86, p = .000). More infants of twin pregnancies had a low birth weight (68.00 versus 10.00%, respectively, OR = 19.13, 95% CI = 10.14-36.06, p = .000), and many had a very low birth weight (10.67 versus 0.67%, respectively, OR = 17.79, 95% CI = 2.33-135.97, p = .000). The infants of twin pregnancies also included more cases of intubation (10.00 versus 0.00%, respectively, p = .000), more cases of hypoglycemia (12.67 versus 5.33%, respectively, OR = 2.57, 95% CI = 1.09-6.08, p = .026), and were admitted much more often to the neonatal intensive care unit (36.00 versus 8.00%, respectively, OR = 6.47, p = .00, CI = 3.29-12.74).Conclusions: Women ≥ 45 years of age with twin pregnancies and their neonates sustain more severe adverse outcome compared to matched pairs of singleton pregnancies. It is recommended that a single embryo transfer should be offered in preference to multiple embryos when those women are undergoing ART.

Abstract
STUDY OBJECTIVE To compare ovarian function between adolescents conceived using assisted reproductive technology (AcART) and adolescents who were conceived spontaneously (AcSP). DESIGN Multicenter study of ovarian function in AcART because of male or tubal infertility. SETTING University Hospital. PARTICIPANTS We evaluated 22 AcART and 53 AcSP at 1-2 years after menarche. The participants were born at term (≥37 weeks of gestation) with normal birth weights (≥2500 g) from singleton pregnancies. INTERVENTIONS None. MAIN OUTCOME MEASURES Differences in ovulation, reproductive hormones, and ovarian morphology. RESULTS AcART had an older age of menarche than that of AcSP, even after adjusting for maternal age at menarche, gestational age, and birth weight (P = .027). AcART had lower incidence of ovulation (P = .021) and higher luteinizing hormone serum levels (P = .01) than those of AcSP. The incidence of oligomenorrhea and the cycle length were similar between AcART and AcSP. AcART had levels of anti-Müllerian hormone, inhibin B, follicle-stimulating hormone, estradiol, and androgens similar to those of AcSP. The ovarian morphology, ovarian volume, and follicle counts were similar in both groups. CONCLUSION AcART had later menarche, lower ovulation rates, and higher luteinizing hormone levels than those of AcSP. Future studies should investigate whether these findings are indicative of a risk of ovarian dysfunction later in life for AcART.

Abstract
BACKGROUND Assisted reproductive technology (ART) treatment tends to involve significant physical and emotional commitments that can impact maternal, infant, and family health and well-being. An in-depth understanding of experiences is necessary to provide adequate support for women and their families during pregnancy and transition to parenthood following ART treatment. The aim of this study was to explore first-time mothers' experiences of pregnancy and transition to parenthood following successful ART treatment in Taiwan. METHOD Twelve first-time mothers who conceived and gave live birth using ART treatment were purposively selected from a fertility centre in Taipei, Taiwan. Women's experiences in pregnancy and in their transition to motherhood were explored using semi-structured in-depth interviews. All interviews were recorded, transcribed, and analysed using the Colaizzi strategy. RESULTS The mothers' accounts reflected three main themes: 'being different from mothers who became pregnant naturally', 'ensuring health and safety of the foetus', and 'welcoming new lives with excitement'. The difference mothers felt about themselves was evident in four subthemes: becoming pregnant after a long wait, feeling vulnerable during pregnancy, relying on family's assistance and support, and worrying about the impact of ART on health. The theme on 'ensuring health and safety of the foetus' encompassed three subthemes: activities to protect the unborn baby, monitoring foetal movement constantly to maintain peace of mind, and receiving foetal reduction for the sake of the pregnancy. Narratives around 'welcoming new lives with excitement' reflected four subthemes: overcoming hardship for worthwhile results, realising one's life and dreams, proving to be fertile enough to give birth, and return to normal life track. CONCLUSION Findings indicate the need for educational and psychosocial interventions to support women and their families physically and psychologically during ART treatment. The stigma related to infertility and the psychosocial support from family are aspects to consider while planning intervention programmes.

Abstract
PURPOSE The aim of the present study was to evaluate the effect of myo-Inositol administration on oocyte quality, fertilization rate and embryo quality in patients with PCOS during assisted reproductive technology (ART) cycles. METHODS Fifty infertile PCOS patients were randomly designated in two groups. In the study group, patients received daily doses of 4 g myo-Inositol combined with 400 mg folic acid and in the control group patients received only 400 mg folic acid from 1 month before starting the antagonist cycle until the day of ovum pick up. Oocyte and embryo qualities were assessed according to European Society of Human Reproduction and Embryology (ESHRE) guidelines. The gene expression of PGK1, RGS2 and CDC42 as a factor of oocyte quality in granulosa cells was analyzed using real-time RT-PCR. Levels of total antioxidant capacity (TAC) and reactive oxygen species (ROS) were evaluated by chemiluminescence assay in follicular fluid. RESULTS The percentage of metaphase II oocyte, fertilization rate and embryo quality significantly improved in the study group (p < 0.05), but the number of retrieved oocytes and follicle count were not statistically different between groups. Furthermore, the gene expression of PGK1, RGS2 and CDC42 was significantly higher in the study group (p < 0.05) but no differences were found between two groups in terms of TAC and ROS levels. CONCLUSIONS The present study findings suggest that myo-Inositol alters the gene expression in granulosa cells and improves oocyte and embryo quality among PCOS patients undergoing ART.

Abstract
OBJECTIVE To compare the neonatal outcomes of very low birth weight (VLBW) infants born after IVF with those of VLBW infants born after natural pregnancy (NP). DESIGN Prospective cohort study. SETTING Not applicable. PATIENT(S) A total of 6,871 VLBW infants born from January 2014 to December 2016. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Neonatal mortality and morbidities. RESULT(S) Of the 6,871 VLBW infants enrolled, 4,438 infants were born as singletons (IVF = 271; NP = 4,167), and 2,433 infants were born as multiplets (IVF = 1,301; NP = 1,132). After adjustment for maternal and neonatal baseline characteristics, infants born as singletons earlier than 28 weeks after IVF more frequently had high-stage retinopathy of prematurity than those born after NP, whereas infants born as multiplets between 28 and 31 weeks after IVF had fewer major congenital anomalies, high-grade intraventricular hemorrhage, and periventricular leukomalacia than those born after NP. Otherwise, no differences in mortality and neonatal outcomes were found. CONCLUSION(S) Very low birth weight infants born as singletons after IVF had comparable neonatal outcomes to those born after NP, except for an increased risk of high-stage retinopathy of prematurity. Very low birth weight infants born as multiplets after IVF had fewer neurologic morbidities than those born after NP.

Abstract
OBJECTIVE To evaluate whether urinary concentrations of organophosphate flame retardant (PFR) metabolites are associated with pregnancy loss among women conceiving with assisted reproductive technology (ART). DESIGN Prospective preconception cohort of subfertile women. SETTING Academic hospital fertility center in Boston, Massachusetts. PATIENT(S) A total of 155 women conceiving 179 pregnancies with ART. INTERVENTION(S) None. Mean exposure to each of five PFR metabolites was estimated by averaging the specific-gravity adjusted natural log concentrations from two urine samples collected during the ART cycle of conception. MAIN OUTCOME MEASURE(S) Adjusted risk ratios (RRs) and 95% confidence intervals (CIs) for biochemical and total pregnancy loss (all losses <20 weeks' gestation) by quartiles of PFR metabolite concentrations were estimated using a repeated measures log-binomial model, accounting for multiple pregnancies per woman. RESULT(S) Of the 179 pregnancies, 31% ended in pregnancy loss (12% in biochemical loss). Among the three metabolites with high detection frequency [bis(1,3-dichloro-2-propyl) phosphate (BDCIPP), diphenyl phosphate (DPHP), and isopropylphenyl phenyl phosphate (ip-PPP)], an increased risk of biochemical loss was observed for women with DPHP concentrations in the fourth vs. first quartile (RR 1.64; 95% CI 0.61-4.39). Also found was an elevated risk of biochemical pregnancy loss among women in the highest quartile of the molar sum of urinary PFR metabolites compared with the lowest (RR 1.89; 95% CI 0.64-5.58). Urinary concentrations of ip-PPP and BDCIPP were not associated with either outcome. CONCLUSION(S) Among subfertile women, urinary DPHP metabolite concentrations measured during the ART cycle of conception may be associated with early pregnancy loss. Although this study is uniquely designed to investigate early markers of pregnancy success and maintenance, the small sample size likely contributed to imprecision. Given their increasing use as replacement chemicals for traditional flame retardants, exposure to PFRs may increase, and more studies will be needed to investigate their potential to impact pregnancy and reproduction.

Abstract
OBJECTIVE To report the utilization, effectiveness, and safety of practices in assisted reproductive technology (ART) globally in 2011 and assess global trends over time. DESIGN Retrospective, cross-sectional survey on the utilization, effectiveness, and safety of ART procedures performed globally during 2011. SETTING Sixty-five countries and 2,560 ART clinics. PATIENT(S) Women and men undergoing ART procedures. INTERVENTION(S) All ART. MAIN OUTCOME MEASURE(S) The ART cycles and outcomes on country-by-country, regional, and global levels. Aggregate country data were processed and analyzed based on methods developed by the International Committee for Monitoring Assisted Reproductive Technology (ICMART). RESULT(S) A total of 1,115,272 ART cycles were reported for the treatment year 2011. Imputing data for nonreporting clinics, 1,643,912 cycles resulted in >394,662 babies, excluding People's Republic of China. The best estimate of global utilization including People's Republic of China is approximately 2.0 million cycles and 0.5 million babies. From 2010 to 2011, the number of reported aspiration and frozen ET cycles increased 13.1% and 13.8%, respectively. The proportion of women aged ≥40 years undergoing nondonor ART increased from 23.2% in 2010 to 24.0% in 2011. As a percentage of nondonor aspiration cycles, intracytoplasmic sperm injection (ICSI) decreased slightly from 67.4% in 2010 to 66.5% in 2011. The IVF/ICSI combined delivery rates per fresh aspiration and frozen ET cycles were 19.8% and 21.4%, respectively. In fresh nondonor cycles, single ET increased from 30.0% in 2010 to 31.4% in 2011, whereas the average number of transferred embryos decreased from 1.95 in 2010 to 1.91 in 2011-again with wide country variation. The rates of twin deliveries after fresh nondonor transfers decreased from 20.4% in 2010 to 19.6% in 2011; the triplet rate decreased from 1.1%-0.9%. In frozen ET cycles performed in 2011, single ET was 51.6%, with an average of 1.59 embryos transferred and twin and triplet rates were 11.1% and 0.4%, respectively. The cumulative delivery rate per aspiration increased from 27.1% in 2010 to 28.0% in 2011. Fresh IVF/ICSI carried a perinatal mortality rate per 1,000 births of 21.0 in 2010 and 16.3 in 2011. This compared with a perinatal mortality rate after frozen ET of 14.6 per 1,000 births in 2010 and 8.6 in 2011. The data presented depend on the quality and completeness of data submitted by individual countries. This report covers approximately two-thirds of'world ART activity. CONCLUSION(S) Global ART utilization, effectiveness, and safety increased between 2010 and 2011.

Abstract
BACKGROUND Previous studies from this as well as other research groups suggested that non-invasive chromosome screening (NICS) with embryo culture medium can be used to identify chromosomal ploidy and chromosomal abnormalities. We here report a series of clinical cases utilizing the technology. METHODS A total of 45 couples underwent in vitro fertilisation during a period between February 2016 and February 2017. Karyotyping revealed normal chromosomes in both partners in 23 couples, and chromosomal rearrangements in at least one partner in 22 couples. Intracytoplasmic sperm injection (ICSI) was used for fertilization. NICS was carried out using embryo culture medium at the blastocyst stage via multiple annealing and looping-based amplification cycles, whole-genome amplification and next-generation sequencing. RESULTS A total of 413 embryos were obtained; 170 blastocysts were subjected to NICS. The screening showed euploidy in 79 embryos, aneuploidy in 52 embryos, and mosaic ploidy for 33 embryos. The rate of euploidy was comparable in couples with normal karyotype (50.7%; 38/75) vs. chromosomal rearrangement (43.2%; 41/95). A total of 52 euploid embryos (50 oocyte retrieval cycles) were transferred in 43 women. Biochemical pregnancy rate was 72.0% (36/50). Clinical pregnancy rate was 58.0% (29/50). The rate of spontaneous miscarriage was 3/29 (none with chromosomal aneuploidy). A total of 27 healthy babies were delivered. CONCLUSIONS NICS could identify embryo chromosomal abnormalities in couples either with or without chromosomal rearrangement, with satisfying clinical outcomes.

[PMID: 30786865 PMCID: PMC6381747 DOI: 10.1186/s12884-019-2213-y] [Citation(s) in RCA: 41] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2018] [Accepted: 02/04/2019] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Although pregnancies conceived by assisted reproductive technology (ART) have a higher risk of maternal/perinatal complications, the overall risk of adverse outcomes necessitating advanced obstetric care has not been closely examined. The present study aimed to assess and compare the risk of maternal/perinatal complications and adverse outcomes in pregnancy and childbirth conceived by ART with those conceived naturally. METHODS This study was conducted as a part of the Japan environment and children's study (JECS), an ongoing nationwide birth cohort study in Japan. The risk of maternal/perinatal complications and adverse outcomes was assessed by mode of conception (natural conception, ovulation induction [OI] without ART, conventional in vitro fertilization and embryo transfer [IVF-ET], or intracytoplasmic sperm injection [ICSI]) using logistic regression and generalized estimating equations controlling for potential confounders. RESULTS The final dataset included women who conceived naturally (N = 90,506), by OI without ART (N = 3939), by conventional IVF-ET (N = 1476), and by ICSI (N = 1671). Compared with women who conceived naturally, those who conceived by conventional IVF-ET were at higher risk of placenta previa (adjusted OR 2.90 [95% CI 1.94, 4.34]), morbidly adherent placenta (6.85 [3.88, 12.13]), and pregnancy-induced hypertension (1.40 [1.10, 1.78]) whereas those who conceived by ICSI had a higher risk of placental abruption (2.16 [1.20, 3.88]) as well as placenta previa (2.01 [1.29, 3.13]) and morbidly adherent placenta (7.81 [4.56, 13.38]). Women who conceived by ART had a higher risk of blood transfusion (conventional IVF-ET: 3.85 [2.52, 5.88]; ICSI: 3.76 [2.49, 5.66]) and ICU admission (conventional IVF-ET: 2.58 [1.11, 6.01]; ICSI: 3.45 [1.68, 7.06]) even after controlling for potential confounders. Neonates conceived by ART had a higher risk of preterm birth (conventional IVF-ET: 1.42 [1.13, 1.78]; ICSI: 1.31 [1.05, 1.64]). CONCLUSIONS Women who conceived by ART had a higher risk of maternal/perinatal complications necessitating advanced obstetric care. Obstetricians should be aware of the increased risk of adverse outcomes among this population.

Abstract
Several hormonal fertility medications have comparable effectiveness. A literature review was conducted into patients' assessments regarding seven medication characteristics including 'side effects' and 'ease of use'. Medline, CINAHL and PsycINFO were searched for female fertility patients' written assessments of a hormonal medication. The tools used were appraised and common (i.e. ≥10%) unpleasant consequences were distinguished from rare ones. The 35 eligible studies did not rely on valid and reliable tools and did not provide patient assessments regarding all seven medication characteristics for any of the globally used medications. Evidence on medications for oocyte triggering was absent and for induction of pituitary quiescence it was scarce. Regarding medications for ovarian stimulation and luteal support, evidence on general side effects (mostly headache), local side effects (mostly pain), 'interference with home life' and 'impact on psychological wellbeing' was found. Evidence on 'ease of use' and 'required education' was only identified for medication for ovarian stimulation. Evidence on 'interference with work life' and 'compliance worry' was absent. This review calls for randomized controlled trials questioning patients with valid and reliable tools. In the meantime, this review's summary of the best available evidence can be integrated in decision aids facilitating personalized and informed medication choices.

Abstract
Few studies have captured oocyte donation (OD) parents' decision processes about intended and actual disclosure over time. Likewise, OD children's perceptions about their family composition during middle childhood are underexplored. To address these gaps, a longitudinally followed cohort of OD recipient families was invited to participate in a qualitative, follow-up study. With an 86% response rate after 12 years, families were composed of oocyte recipient mothers (n = 6) and biological fathers (n = 6) representing 12 donor-oocyte conceived children (10.33 ± 1.23 years; mean ± SD). Of the 12 children, two that were aware and two that were unaware of their conceptual origins completed conversational interviews. Only one family in the initial cohort had disclosed OD to their children by the 12-year follow-up, despite 43% of parents intending to disclose and another 43% undecided about disclosure during pregnancy. Four parental disclosure patterns emerged at 12 years: (i) wanting to disclose; (ii) conflicted about disclosure; (iii) not planning to disclose; and (iv) having disclosed. Children that were unaware of their conceptual origins displayed no knowledge of their method of conception. There is a need for family-centric interventions to assist 'wanting to disclose' parents in their disclosure process and 'conflicted about disclosure' parents in their decision-making process post-OD treatment.

Risk factors for gestational diabetes mellitus among women screened with the two-step and one-step methods: A before-and-after study. Taiwan J Obstet Gynecol 2019; 57:668-671. [PMID: 30342648 DOI: 10.1016/j.tjog.2018.08.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/23/2018] [Indexed: 12/16/2022] Open
Abstract
OBJECTIVE To compare the risk profiles for gestational diabetes mellitus (GDM) using a one-step and two-step screening method and diagnostic criteria. MATERIALS AND METHODS A retrospective cohort study was conducted among women screened using Carpenter and Coustan's (C&C) criteria (two-step method) and the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria (one-step method). All deliveries after 28 weeks of gestation, except for pregnancies complicated by pre-pregnancy diabetes mellitus, were analyzed. Multiple logistic regression was used to assess the associations between GDM and various potential risk factors. RESULTS Risk factors for C&C-defined GDM were pre-pregnancy body mass index >24.2 kg/m2 (adjusted odds ratio [OR] 2.49, 95% confidence interval [CI] 1.92-3.23), maternal age at delivery >34 years (adjusted OR 2.46, 95% CI 1.96-3.09), history of fetal death (adjusted OR 2.56, 95% CI 1.37-4.78), and chronic hypertension (adjusted OR 3.66, 95% CI 1.50-8.91). In addition to these factors, conception assisted by reproductive technology (adjusted OR 1.64, 95% CI 1.19-2.25) and genetic amniocentesis (adjusted OR 1.19, 95% CI 1.03-1.38) were IADPSG-defined GDM risk factors. CONCLUSION Risk factors for GDM differ with the diagnostic criteria used. This information is important when changing GDM screening strategies from the two-step approach to the one-step approach.

Morphological changes in the porcine cervix: A comparison between nulliparous and multiparous sows with regard to post-cervical artificial insemination. Theriogenology 2019; 127:120-129. [PMID: 30685687 DOI: 10.1016/j.theriogenology.2019.01.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2018] [Revised: 12/23/2018] [Accepted: 01/09/2019] [Indexed: 01/26/2023]
Abstract
In recent decades, new artificial insemination (AI) methods, such as post-cervical AI (PCAI), have been developed in pig. PCAI involves crossing the cervix to deposit the sperm in the uterine body. Although PCAI application in sows is frequent, its application in nulliparous (gilts) females it is still limited due to the difficulty of passing through the cranial part of the cervical lumen. We hypothesized that ageing and parity would modify the cervical canal, facilitating the introduction of AI devices through the cervix. The aim was to compare the morphology of the uterus at different levels between multiparous and nulliparous females. Morphological analysis of the uterus pointed to a longer cervix (25.9 ± 4.6 vs. 21.6 ± 3.3 cm, p < 0.001) and greater length of the part of the reproductive tract involved in PCAI (from rima vulvae to the last cervical cushion) (56.2 ± 6.0 vs. 50.3 ± 5.2 cm, p < 0.001) in multiparous sows compared with nulliparous animals. As regards the structure of the vaginal and uterine parts of the cervix (the part in contact with the vagina and uterine body, respectively), the cross-sectional area, perimeter and total thickness were greater in the uterine part of multiparous than of nulliparous animals (area: 4.07 ± 1.46 vs. 2.46 ± 0.56 cm2, p < 0.01; perimeter: 8.50 ± 1.44 cm vs. 6.28 ± 0.92 cm, p < 0.001; thickness: 10.79 ± 0.96 vs. 8.35 ± 0.62 mm, p < 0.05), but not in the vaginal part. The tissue content analysed in histological cross-sections also showed differences between female groups, a greater content of connective tissue (58.86 ± 10.78 vs. 67.60 ± 13.38%, p < 0.001) and a lower amount of muscle fibres (39.79 ± 10.24 vs. 30.66 ± 13.69%, p < 0.001) being observed in multiparous sows. Finally, silicone casts of the cervical lumen revealed differences between the two groups in the size and shape of the ridges in the lumen trajectory. Parity, which is also influenced by ageing, determines important changes in the size, structure and tissue content of the cervix wall, as well as in the morphology of the cervical canal, which may be responsible for the different levels of performance of PCAI in the female populations. Therefore, the future design of AI strategies and catheters should take into consideration the morphological variations of the cervix lumen, which will depend on age and parity of the females.

Abstract
Objective: Previous studies have indicated that women with assisted reproductive technology (ART) pregnancy have an increased risk of preeclampsia. The aim of this current study was to estimate, through a systematic review and meta-analysis of cohort studies, the risk of preeclampsia in women who conceived with ART.Materials and methods: We searched ISI Web of Knowledge, Medline/PubMed, Scopus and Embase up to August 2017 for English-language articles pertaining to risk of preeclampsia in ART pregnancy using standard keywords. Data extraction was conducted by two authors and quality of the studies was assessed using the Newcastle-Ottawa Scale. A random-effects model was used for the meta-analysis.Results: In total, 72 cohort studies (n = 164 870) were included. The results of Cochran test and I2 statistic indicated considerable heterogeneity among studies (Q = 15 415.61, df = 71, p < .001, I2=99.5%). The pooled estimate of preeclampsia risk using the random effects model was 10.8% (95% CI: 9.10-12.5). Furthermore, the funnel plot and Begg's test showed evidence of publication bias.Conclusions: We found that the risk of preeclampsia was very high among women who conceived with ART. Women should be counseled carefully before undergoing ART treatment.

Abstract
BACKGROUND There is an increasing prevalence of women who tend to delay childbirth until a very advanced age. However, there is sparse data regarding very advanced maternal age (vAMA) and the interplay between vAMA and assisted reproductive technology (ART) on adverse perinatal outcomes. The study aimed to assess the risk of adverse maternal and neonatal outcomes of vAMA women (≥43 years), and to investigate the effect of maternal age on adverse maternal and neonatal outcomes in ART pregnancies. METHODS Data was obtained from a population-based retrospective cohort of women who delivered in Ontario, Canada, between April 1st, 2012 and March 31st, 2015. The adjusted relative risks (ARR) and 95% confidence intervals (CI) for adverse maternal and neonatal outcomes were estimated by using multivariate log-binomial regression models among age groups. All models were stratified by the utilization of ART (ART and spontaneous conceptions). RESULTS Women at vAMA had a higher risk of composite outcome comprised of preeclampsia, intrauterine growth retardation, stillbirth, and placental abruption than the younger counterparts (ARR = 1.38, 95% CI: 1.23-1.55 compared to mothers aged 20-34; ARR = 1.26, 95% CI: 1.12-1.42 compared to mothers aged 35-42). Increased risk of the primary outcome in ART compared to spontaneous conception was only observed in women aged 20-34 years (ARR = 1.24, 95% CI: 1.14-1.35). For women conceived with ART, the risk for the primary outcome significantly increased in women at vAMA (ARR = 1.29, 95% CI: 1.01-1.65 compared to mothers aged 20-34; ARR = 1.36, 95% CI: 1.06-1.74 compared to mothers aged 35-42). CONCLUSION Women at vAMA have higher risks of adverse maternal and neonatal outcomes. Although the utilization of ART may carry an independent role for adverse perinatal outcomes, it does not further enhance the adverse effect of vAMA.

Abstract
Aim: The aim of the study was to compare the perinatal outcomes between singletons following vanishing twin phenomenon and singletons arising from initial single gestational sac following assisted reproductive technology (ART) treatment. Setting and Design: This was a retrospective cohort study. Materials and Methods: A retrospective cohort study included analysis of all singleton births following ART over a period of 7 years (January 2010 –December 2016). All women who underwent fresh or frozen embryo ART cycles were followed up. The study population included all singleton births following spontaneous reduction of one of the gestational sacs in dichorionic diamniotic twin pregnancies. The perinatal outcome of this group was compared with those of singletons arising from the initial single gestational sac. Results: A total of 521 singleton births were recorded during the study period. In the study group, 72 singleton births had spontaneous reduction of one of the gestational sacs (vanishing twin group) and the remaining 449 had an initial single gestational sac. The risk for low birth weight (LBW) (14/72, 19.4% vs. 96/449, 21.6%) and preterm birth (PTB) (17/72, 23.6% vs. 134/449, 29.8%) was not significantly different between those singletons who had spontaneous reduction from two gestational sacs to single sac compared to those with initial single sac. The miscarriage rate was significantly lower in vanishing twin group compared to control group (7/84, 8.3% vs. 157/622, 25.2%; P = 0.01). The subgroup analysis based on spontaneous reduction occurring before or after the appearance of the embryonic pole also showed similar risk of PTB (11/41, 26.8.% vs. 9/31, 29.0%) and LBW (7/41, 17.1% vs. 9/31, 29.0%). Conclusion: Perinatal outcomes in singleton live births following vanishing twin phenomenon are similar to those pregnancies with an initial single gestational sac following ART.

Abstract
Sex steroid hormones are major regulators of uterine and placental growth and functions, as well as many other biological processes. To examine the mRNA expression of nuclear estrogen (ESR1 and 2) and progesterone (PGRAB and B) receptors in different compartments of the uterus and placenta, tissues were collected in experiment 1 on days 16, 20, and 28 after natural mating (NAT) and on day 10 after estrus (nonpregnant controls [NP]); and in experiment 2 on day 22 of NAT, and pregnancies established after transfer of embryos generated through mating of FSH-treated ewes (NAT-ET), in vitro fertilization (IVF), or in vitro activation (parthenotes). In experiment 1, ESR1 expression in endometrial stroma (ES), endometrial glands (EGs), and myometrial blood vessels (MBVs), ESR2 in endometrial blood vessels (EBV), PGRAB in ES, and PGRB in ES, EG, and MBV was greater in pregnant than NP ewes depending on the day of pregnancy. The day of pregnancy affected the expression of ESR1 in MBV, ESR2 in EBV and MBV, and PGRAB in ES. In experiment 2, ESR1, PGRAB, and PGRB in EG, but not in other compartments, was greater in NAT-ET than NAT, and PGRB was greater for NAT-ET than IVF. These data demonstrate that ESR and PGR expression differ in pregnant versus NP ewes in selected compartments and was affected by pregnancy stage or embryo origin in selected utero-placental compartments. Thus, sex steroid hormone mRNA expression is differentially regulated in a spatiotemporal manner in the uterus and placenta and is affected by the application of assisted reproductive technology in sheep.

Abstract
The aim of this study is to evaluate the outcomes of single embryo transfer in patients with good ovarian reserve in the IVF program using time-lapse microscopy. This is a retrospective cohort study in a private IVF center in Russia. Comparison was done between 90 IVF cycles using time-lapse (study group) and 113 IVF cycles using standard culture (control group). Within each group, subgroups were selected with selective transfer of one embryo for 5 days (5SET) and elective transfer of one embryo for 5 days (5eSET). The primary outcome of the study was pregnancy rate. Secondary outcomes were miscarriage rates, live birth. Pregnancy rate did not significantly differ between the groups - 64.2% in the study group and control group. In the study group, the delivery rate was 54% in the subgroup 5eSET and 51.1% in the subgroup 5SET (p = .940). In the control group, the type of the embryo transfer significantly influenced on the delivery rate: in the 5eSET subgroup the birth rate was 54.4%, and in the 5SET subgroup it was 34.3% (p = .055; by Fisher's exact method p = .052). There were no adverse effects of the intervention. Selection of a single blastocyst based on information derived from time-lapse monitoring can help embryo selection for transfer.

Abstract
RESEARCH QUESTION What are the live birth rates and neonatal outcomes following cleavage-stage embryo transfer and blastocyst transfer in a freeze-all treatment scenario? DESIGN This was a retrospective cohort study. All good-quality embryos were frozen on the third day; the remaining embryos were grown on until they reached blastocyst stage and then frozen. Between 2007 and 2016, 11,801 patients underwent cleavage-stage embryo transfer and 1009 patients underwent blastocyst transfer in the first treatment cycle using the freeze-all strategy. The live birth rate and neonatal outcomes were evaluated. RESULTS The live birth rate in the first frozen embryo transfer cycle was higher following blastocyst transfer than following cleavage-stage transfer (69.1% versus 55.5%, P < 0.01), but there was no difference in live birth rate in the second frozen embryo transfer cycle between blastocyst transfer and cleavage-stage transfer (45.2% versus 52.7%, P > 0.05). Similarly, no difference was found in the cumulative live birth rate for the first complete IVF cycle (71.1% versus 69.2%, P > 0.05). Blastocyst transfer gave a higher risk of preterm singleton delivery than did cleavage-stage transfer. However, there was no difference in the risk of early preterm delivery, low birth weight, very low birth weight, high birth weight and very high birth weight between the two groups. CONCLUSIONS There is no evidence to support the superiority of blastocyst transfer compared with cleavage-stage transfer in a freeze-all treatment scenario. There may be a higher risk of preterm singleton delivery following blastocyst transfer than following cleavage-stage transfer but further studies are needed to verify this.

Abstract
Background Growing evidence indicates that the risk of obstetric and perinatal outcomes is higher in women with assisted reproductive technology (ART). However, there is little known about pregnancy related complications and co-morbidity in gestational diabetes mellitus (GDM) following singleton pregnancies achieved by ART in comparison with spontaneous conception (SC). Methods Two hundred sixty singleton pregnant women conceived by ART and 314 pregnant women conceived by spontaneous conception (SC) were participated in this prospective cohort study. All participants were enrolled after GDM screening through one-step oral glucose tolerance test (OGTT) and then grouped into GDM and non-GDM groups. Women were followed for pregnancy outcomes including pregnancy-induced hypertension (PIH), preeclampsia, antepartum hemorrhage (APH), cesarean section (CS), preterm birth (PTB), intrauterine growth restriction (IUGR), being small or large for gestational age (SGA or LGA), macrosomia, low birth weight (LBW), respiratory distress, neonatal hypoglycemia, NICU admission and perinatal mortality from antenatal visits to delivery. Confounding factors were adjusted in logistic regression model in order to estimate adjusted odds ratios (aORs). Results Among 260 ART and 314 SC, 135 and 152 women were GDM women, respectively. Higher maternal age and pre-gravid BMI, shorter duration of gestation and lower gestational weight gain were observed in GDM groups (ART-GDM and SC-GDM) compared to those of the SC group. ART-GDM group had a higher risk (95% confidence interval) of obstetric complications including PIH [aOR:7.04 (2.24–22.15)], preeclampsia [aOR:7.78 (1.62–37.47)], APH [aOR:3.46 (1.28–9.33)], emergency CS [aOR:2.64 (1.43–4.88)], and perinatal outcomes such as PTB [aOR:3.89 (1.51–10.10)], LBW [aOR:3.11 (1.04–9.30)] and NICU admission [aOR:4.36 (1.82–10.45)], as well as neonatal hypoglycemia [aOR: 4.91 (1.50–16.07)], compared to SC group. SC-GDM group showed a higher risk of PIH [aOR: 4.12 (1.31–12.89)], emergency CS [aOR: 2.01 (1.09–3.73] and LGA [aOR: 5.20 (1.07–25.20)], compared to SC group. Additionally, ART group had a higher risk of PIH [aOR: 3.46(1.02–11.68), preeclampsia 5.29 (1.03–27.09), and NICU admission [aOR: 2.53 (1.05–6.09)] compared to SC. Insulin requirement (41.8% vs. 25.7%) was significantly higher in ART-GDM group compared to SC-GDM group. Conclusion The findings of this study suggest that GDM occurring after ART conception increases the risk of adverse obstetric and perinatal outcomes.

Using the EngagedMD multimedia platform to improve informed consent for ovulation induction, intrauterine insemination, and in vitro fertilization. Fertil Steril 2018; 110:1338-1346. [PMID: 30503133 DOI: 10.1016/j.fertnstert.2018.08.045] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2018] [Revised: 08/19/2018] [Accepted: 08/20/2018] [Indexed: 12/16/2022]
Abstract
OBJECTIVE To study patient and provider feedback on how a multimedia platform (EngagedMD) helps patients to understand the risks and consequences of in vitro fertilization (IVF), ovulation induction (OI), and intrauterine insemination (IUI) treatments and the impact of the informed consent process. DESIGN Prospective survey study. SETTING IVF units in the United States. PATIENT(S) Six-thousand three-hundred and thirty-three patients who viewed the multimedia platform before IVF or OI-IUI treatment at 13 U.S. IVF centers and 128 providers. INTERVENTION(S) Quantitative survey with 17 questions. MAIN OUTCOME MEASURE(S) Assessment of the impact of a multimedia platform on patient anxiety, comprehension, and satisfaction and provider/nurse feedback related to the informed consent process. RESULT(S) The survey was completed by 3,097 respondents (66% IVF treatment; 34% OI-IUI treatment) and 44 providers. Overall, 93% felt the media platform was intuitive, and 90% and 95% felt it had appropriate duration and detail, respectively. Most agreed/strongly agreed it better prepared them to consent (88%), increased their comfort in pursuing treatment (77%) and increased their satisfaction with their care (83%). Compared with the OI-IUI group, statistically significantly more participants who viewed the IVF media platform strongly agreed that the comprehension questions reinforced key concepts (47% vs. 40%), educated them about treatment risks (55% vs. 44%), helped them ask providers informed questions (45% vs. 36%), and better prepared them to sign consent forms (46% vs. 37%). Overall, 63% of providers felt that the media platform improved patient learning, made patients more accountable, and standardized information dissemination. CONCLUSION(S) The EngagedMD media platform improves patient knowledge, satisfaction, and control over medical decision making and better prepares patients to give informed consent. Furthermore, it is well-liked by providers and is easily implemented.

Abstract
OBJECTIVE To investigate the effectiveness of Tornado and Hilal (Cook Medical, Bloomington, IN) hysteroscopic proximal tubal occlusion (HPTO) for hydrosalpinx (HX) treatment before in vitro fertilization (IVF) and embryo transfer (ET) in patients with dense pelvic adhesions or low ovarian reserve. DESIGN A retrospective study of patients treated between May 2014 and May 2016 (Canadian Task Force classification III). SETTING A university-affiliated center. PATIENTS One hundred fifty women with unilateral or bilateral HX who were not candidates for laparoscopic surgery. INTERVENTION Tornado or Hilal HPTO before IVF-ET and/or frozen ET. MEASUREMENTS AND MAIN RESULTS The main outcome was the cumulative live birth rate. Tornado or Hilal placement was successful for 143 (95.3%) patients. Of the 132 patients who underwent 204 ET cycles, 86 (65.2%) conceived, and 78 (59.1%) resulted in live births. The overall early and late miscarriage rates per clinical pregnancy were 12.8% and 1.1%, respectively. The ectopic pregnancy rate was 2.3%. No major complications occurred. CONCLUSION Tornado or Hilal HPTO is an effective alternative for treating HX before IVF-ET/frozen ET in patients with dense pelvic adhesions or low ovarian reserve.

Abstract
CFTR protein regulates electrolyte and fluid transport in almost all tissues with exocrine function, including male reproductive tract. Mutation of CFTR gene causes cystic fibrosis (CF), which affects the function of several organs, and impairs male fertility. The role of CFTR protein in different compartments of male reproductive tract (testis, epididymis, sperm) as well as an impact of CFTR mutation(s) on male fertility phenotype is discussed in relation with the choice of optimal technique for Assisted Reproductive Techniques (ART) management.

The growth of assisted reproductive treatment-conceived children from birth to 5 years: a national cohort study. BMC Med 2018; 16:224.

Abstract
BACKGROUND Birth weight and early child growth are important predictors of long-term cardiometabolic disease risk, in line with the Developmental Origins of Health and Disease hypothesis. As human assisted reproductive technologies (ARTs) occur during the sensitive periconceptional window of development, it has recently become a matter of urgency to investigate risk in ART-conceived children. METHODS We have conducted the first large-scale, national cohort study of early growth in ART children from birth to school age, linking the register of ART, held by the UK's Human Fertilisation and Embryology Authority, to Scottish maternity and child health databases. RESULTS In this study of 5200 ART and 20,800 naturally conceived (NC) control children, linear regression analysis revealed the birthweight of babies born from fresh embryo transfer cycles is 93.7 g [95% CI (76.6, 110.6)g] less than NC controls, whereas babies born from frozen embryo transfer (FET) cycles are 57.5 g [95% CI (30.7, 86.5)g] heavier. Fresh ART babies grew faster from birth (by 7.2 g/week) but remained lighter (by 171 g), at 6-8 weeks, than NC babies and 133 g smaller than FET babies; FET and NC babies were similar. Length and occipital-frontal circumference followed the same pattern. By school entry (4-7 years), weight, length and BMI in boys and girls conceived by fresh ART and FET were similar to those in NC children. CONCLUSIONS ART babies born from fresh embryo transfer grow more slowly in utero and in the first few weeks of life, but then show postnatal catch up growth by school age, compared to NC and FET babies. As low birth weight and postnatal catch-up are independent risk factors for cardiometabolic disease over the life-course, we suggest that further studies in this area are now warranted.

Abstract
RESEARCH QUESTION What were utilization, outcomes and practices in assisted reproductive technology (ART) in Africa in 2013? DESIGN To initiate a data registry in Africa, retrospective summary data were collected in a cross-sectional survey. RESULTS Forty ART centres from 13 countries collectively reported 25,770 initiated cycles. Regional ART utilization could not be established due to large inter-country variations and insufficient data. The pregnancy rate per aspiration for fresh non-donor IVF and intracytoplasmic sperm injection was 28.0% and 35.8%, with a preponderance of women under 35 years (57.3%). Deliveries were reported for only 56.1% of pregnancies; the remainder were lost to follow-up. A mean of 2.41 embryos were transferred. The multiple delivery rate was 26.7% (25.5% twins and 1.2% triplets). Most twins (52.7%) and triplets (73.7%) were born pre-term. Oocyte donation represented 7% of all fresh and frozen transfers. CONCLUSION This marks the beginning of an ART registry in Africa, Since ART utilization could not be established, the degree of access to ART remains speculative. Pregnancy rates were favourable but underpinned by a preponderance of young women and the transfer of multiple embryos. Efforts are needed to explore treatment barriers, improve pregnancy follow-up and reduce the high rate of multiples. This inaugural report from the African Network and Registry for Assisted Reproductive Technology (ANARA) indicates a willingness and ability of ART centres to voluntarily report and monitor utilization and outcomes of ART, which reflects a rising standard of ART in Africa. It is anticipated that more centres and countries will join ANARA to continue this trend.

Abstract
RESEARCH QUESTION How might time to healthy singleton delivery affect decision-making during infertility treatment? DESIGN This was a Delphi consensus investigating expert opinion that comprised three steps. In Step 1, 12 experts developed statements. In Step 2, 27 experts (including 12 from Step 1) voted (online survey) on their agreement/disagreement with each statement (providing reasons). Consensus was reached if ≥66% of participants agreed/disagreed. Statements not reaching consensus were revised and the process repeated until consensus was achieved. In Step 3 details of the final agreed statements were communicated. RESULTS Twelve statements were developed, and consensus (agreement) was reached on all after one round of voting. CONCLUSIONS Time to healthy singleton delivery should be taken into consideration when making decisions related to infertility treatment, and it is important that fertility treatment is provided in a timely manner, avoiding over- or under-treatment. In all subfertile women <40 years old, IVF outcomes could be optimized by performing up to six single-embryo transfers and certain procedures might reduce time to healthy singleton delivery. These procedures include preimplantation genetic testing for aneuploidies, frozen replacement cycles immediately after failed fresh cycles and use of gonadotrophin-releasing hormone antagonists. Finally, the number of oocytes retrieved should be maximized to increase cumulative live birth rate.

Abstract
PURPOSE Implantation failure is a major limiting factor of successful in vitro fertilization (IVF). The objective of this study was to determine if endometrial mechanical stimulation (EMS) by endometrial biopsy in the luteal phase of the cycle prior to embryo transfer (ET) improves clinical outcomes in an unselected subfertile population. METHODS Double-blind, randomized controlled trial of EMS versus sham biopsy and odds of clinical pregnancy after IVF and embryo transfer. Secondary outcomes included spontaneous miscarriage and live birth. RESULTS One hundred women enrolled and were randomized from 2013 to 2017. Enrollment was terminated after futility analysis showed no difference in clinical pregnancy between EMS versus control, 47.2% vs 61.7% (OR 0.55, 95% CI 0.25-1.23, p = 0.15). There were no significant differences between women who underwent EMS and those who did not in terms of positive pregnancy test 54.7% vs 63.8% (OR 0.69, 95% CI 0.31-1.53, p = 0.36), miscarriage 7.5% vs 2.1% (OR 3.76 95% CI 0.41-34.85, p = 0.22), or live birth 43.4% vs 61.7% (OR 0.48 95% CI 0.21-1.06, p = 0.07). CONCLUSIONS EMS in the luteal phase of the cycle preceding embryo transfer does not improve clinical outcomes in an unselected subfertile population and may result in a lower live birth rate. We caution the routine use of EMS in an unselected population.

Abstract
Polycystic ovary syndrome (PCOS) affects 6–10% of women and could be considered one of the most common endocrine alterations in women of reproductive age. The syndrome is characterized by several hormonal and metabolic alterations, including insulin resistance and hyperandrogenism, which play a severe detrimental role in the patient’s fertility. We aimed to offer an overview about drug metabolism in the PCOS population. Nevertheless, we did not find any study that directly compared drug metabolism between PCOS and healthy women. We therefore decided to summarize briefly how hormonal and insulin sensitizer drugs act differently in healthy and PCOS women, who show altered steroidogenesis by theca cells and metabolic imbalance, focusing especially on assisted reproductive techniques. To date, data about drug metabolism in the PCOS population appears to be extremely limited. This important gap could have significant implications for therapeutic approaches and future perspectives: the dosage of drugs commonly used for the treatment of PCOS women should be tailored according to each patient’s characteristics; we should implement new clinical trials in order to identify the best pharmacologic strategy for PCOS patients undergoing in vitro fertilization (IVF); it would be advisable to create an international expert panel to investigate the drug metabolism in the PCOS population.

Abstract
Rapid development in the area of assisted reproductive technology (ART), has benefited mankind by addressing reproductive problems. However, the emergence of new technologies and techniques raises various issues and discussions among physicians and the masses, especially on issues related to bioethics. Apart from solutions provided using conventional bioethics framework, solutions can also be derived via a complementary framework of bioethics based on the Higher Objectives of the Divine Law (Maqasid al-Shariah) in tackling these problems. This approach in the Islamic World has been applied and localised in the Malaysian context. Thus, this paper highlights a conceptual theoretical framework for solving current bioethical issues, with a special focus on ART in the Malaysian context, and compares this theory with conventional theories of bioethics.

Abstract
INTRODUCTION The health and development of newborn children born via assisted reproductive technology (ART), as well as their health in adulthood, have raised great concern. This study was designed to investigate whether ART children have differences in the levels of trace elements compared with naturally conceived children. METHODS This study included those ART children and controls aged 1 to 12 years assessed with a follow-up protocol. Serum levels of the trace elements zinc, copper, iron, calcium, magnesium and lead were determined and analyzed. RESULTS There were no significant differences in age, gender or body weight between the ART and control groups. There were no significant differences in the rates of deficiency or excess of trace elements between the two groups. Serum lead levels in children born via ART were significantly higher than those in the controls, whereas the levels of zinc and iron were significantly decreased in the ART group, although these levels were still within the normal ranges. DISCUSSION These results indicate the need to monitor the blood levels of zinc, iron and lead in ART children aged 1-6 years old. These findings contribute to our understanding on the long-term safety of ART and may facilitate screening for potential diseases related to trace elements.

Abstract
OBJECTIVE This secondary analysis aimed to identify the incidence and risk factors associated with monozygotic twins (MZTs) after assisted reproductive technology (ART). STUDY DESIGN In this retrospective cohort observational study, the treatment cycles were compared between MZT and non-MZT pregnancies using logistic regression analyses. Of the 11,501 patients with 13,225 pregnancies, 166 MZTs were diagnosed (1.44% in ART pregnant patients; 1.25% in pregnant cycles). RESULTS Results of the logistic analysis revealed that embryo stage at transfer and number of good-quality embryos were independent predictive factors for MZTs. The thresholds for two factors were 3.5 and 3.5. The efficacy of embryo stage at transfer and number of good-quality embryos for MZTs were evaluated using receiver-operating characteristic curves. The areas under the curve (AUCs) for these two parameters were 0.708 and 0.633, respectively. Adding number of good quality embryos increased the discriminative ability of the model (AUC = 0.745). CONCLUSIONS The incidence of MZTs, subsequent to ART, is quite high. Extended culture (≥3.5 days), together with the number of good-quality embryos (≥3.5), conferred the greatest risk of producing MZTs.

Abstract
PURPOSE Although the clinical value of time-lapse imaging (TLI) systems in in vitro fertilization (IVF) cycles is still debated, its prevalence worldwide seems to be expanding. The situation of TLI in the USA has been recently surveyed, but these results might not be transposable to other countries with different IVF regulation and funding such as France. This study evaluated the TLI situation in French IVF laboratories. METHODS An anonymous online cross-sectional survey was sent by email to 210 embryologists in September and October 2017. Laboratories, demographics, TLI clinical use, purchasing plan, and embryologists' opinions were analyzed using logistic regression to calculate odds ratio. RESULTS Of the 210 lab directors surveyed, 78 responded (37.1%), 43 (55%) working in private IVF laboratories and 35 (45%) in public hospitals. Thirty (38.5%) were TLI users. The odds of TLI possession were not statistically different according to laboratory sector or size. Most embryologists (n = 21, 70%) used TLI for unselected patients. Cost was the main reason given by non-users for not implementing TLI (n = 24, 50%). Most respondents were convinced that TLI is superior to standard morphology (n = 52, 73.2%) and that TLI improves culture conditions (n = 62, 84.9%). However, half (n = 39, 54.9%) indicated that evidence was still lacking to assert TLI clinical usefulness. CONCLUSION The prevalence of TLI systems and embryologists' opinion in France was slightly different from the American situation. The different regulation and funding policy might account for some differences in terms of TLI use and perception.

Abstract
OBJECTIVE To investigate the impact of peri-implantation prednisolone use and its duration in antagonist co-treated assisted reproductive technology (ART) cycles of patients with good prognosis. MATERIALS AND METHODS Infertile patients treated with gonadotropin-releasing hormone antagonist protocol between January 2010 and June 2013 were included. The patients in group A (n=196) received no prednisolone. The patients in groups B (n=397) and C (n=371) received 5 mg oral prednisolone daily, for 4 and 12 days following embryo transfer, respectively. The main outcome parameter was live birth rate. RESULTS The ages of the groups were 30.1±4.6, 31.5±4.5, and 30.9±4.7 years, respectively (p=0.163). There was no statistically significant difference between the groups regarding cycle characteristics. Implantation rates were 20.7%, 24.6%, and 23.8%, respectively (p=0.163). Miscarriage rates were 1.5%, 3.5%, and 3.2%, respectively (p=0.859). Live birth rates were 28.7%, 29.3%, and 32.8%, respectively (p=0.482). CONCLUSION Empiric prednisolone administration during the peri-implantation period does not seem to have beneficial effects in ART cycles of patients with good prognosis.

Abstract
RESEARCH QUESTION Why are comprehensive and detailed reports of local or national utilization outcomes of assisted reproductive technology (ART) lacking in China? DESIGN Retrospective collection of data on intrauterine insemination (IUI) and IVF and intracytoplasmic sperm injection (ICSI) in Beijing, including all 12 registered institutions with cycles, started between 1 January 2013 and 31 December 2015. RESULTS Clinical pregnancy rates (CPR) per aspiration and fresh embryo transfer were 39.1% and 43.2% in 2013, 40.1% and 45.4% in 2014, and 37.8% and 44.5% in 2015; live birth rates (LBR) per aspiration and per fresh embryo transfer were 31.7% and 35.0%, 32.3% and 36.6%, and 30.3% and 35.6%, respectively. In frozen embryo transfer (FET) cycles, the CPR per thawed transfer was 43.4%, 47.2% and 46.2%, respectively, resulting in LBR of 34.3%, 37.4% and 36.5%. The prevalence of multiple pregnancies was 28.0-31.3% for fresh embryo transfer, and 23.5-25.9% for FET. The LBR was 8.8-9.1% after IUI with husband or partner's semen (IUI-H), and 16.7-19.7% after IUI with donor semen (IUI-D). The birth defect rate among live born infants was 1.52%, 0.42% and 0% after IUI-H, 1.05%, 0.39% and 0.66% after IUI-D, 0.71%, 0.56% and 0.46% after fresh embryo transfer, and 0.73%, 0.20% and 0.18% after FET in 2013, 2014 and 2015, respectively. CONCLUSIONS In Beijing over 3 years, the number of IVF-ICSI cycles has increased and the number of IUI cycles has decreased; IVF-ICSI outcomes are better and safer. Further effort should be made to lower the multiple pregnancy rates. A Chinese nationwide ART registry should be promoted.

Sperm lipidic profiles differ significantly between ejaculates resulting in pregnancy or not following intracytoplasmic sperm injection. J Assist Reprod Genet 2018; 35:1973-1985. [PMID: 30105539 DOI: 10.1007/s10815-018-1284-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2018] [Accepted: 08/02/2018] [Indexed: 12/17/2022] Open
Abstract
Although assisted reproduction techniques involve the use of semen samples, there is little scientific methodology applied when selecting sperm. To select the most appropriate spermatozoa, first we need to define the optimal molecular characteristics. Sperm lipids may contribute to sperm function, thus our aim was to compare the lipidic profiles of sperm samples used in intracytoplasmic sperm injection cycles that ultimately led to a pregnancy with those that did not.Spermatozoa from infertile patients after intracytoplasmic sperm injection (group non-pregnant, n = 16; vs. group pregnant, n = 22) were analyzed for lipid composition using ultra-high performance liquid chromatography coupled to mass spectrometry, by means two platforms for measuring fatty acyls, bile-acids, lysoglycerophospholipids, glycerolipids, cholesteryl-esters, sphingolipids, and glycerophospholipids. Lipid levels were compared using a univariate test and multivariate analyses after logarithmic transformation.We detected 151 different lipids in the sperm samples, 10 of which were significantly increased in sperm samples from the NP group, ranging from 1.10- to 1.30-fold change. These were primarily ceramides, sphingomyelins and three glycerophospholipids, a lysophosphatidylcholine, and two plasmalogen species. Additionally, 2-Monoacylglycerophosphocholine were also found in higher levels in non-pregnant group.Our results describe the composition of sperm lipids linked to optimal sperm function, opening new possibilities for the development of male fertility diagnostic tools and culture media formulations to improve sperm quality and enhance reproductive results. Given that lipids compose the majority of the sperm plasma membrane, this information is also useful in designing new sperm selection tools that will allow for the selection of the best spermatozoa.

Abstract
BACKGROUND Pregnancy after infertility is a challenging experience. The first-trimester screening test may add stress. Partner support reduces psychological distress in pregnant women after spontaneous conception. No data are available for women who conceive via assisted reproductive technology. AIM To assess whether there was a difference between couples who underwent assisted reproductive technology and couples who conceived spontaneously in the support they felt they provided to their partner and whether their perception of support received from their partner reduced their distress. METHODS This longitudinal prospective study included 52 women (spontaneous conception) and 53 women (assisted reproductive technology), as well as their partners. Participants completed the state scale of the State-Trait Anxiety Inventory, the Edinburgh Depression Scale, and two partner-support subscales of the Dyadic Coping Inventory: before prenatal testing (gestational age 12 weeks), immediately after receiving the results (gestational age of approximately 14 weeks), and once all the prenatal screenings had been completed (gestational age 22 weeks). FINDINGS Women who underwent assisted reproductive technology felt less able to help their partner cope with stress and felt their partner was less able to help them cope with stress than women with spontaneous pregnancy. This difference was not observed in men. Higher perceived partner support lowered the anxiety and depression of couples who conceived spontaneously, but did not benefit couples who followed fertility treatment. CONCLUSION These results add to our knowledge of the emotional state of women and their partners during pregnancy after infertility. This knowledge may allow prenatal care providers to offer specialized counselling to women and their partners in the transition from infertility to parenthood.

Abstract
PURPOSE To analyse the impact of female characteristics on assisted reproductive technology outcome among male haematological cancer survivors. METHODS A retrospective analysis of 93 haematological cancer survivors attending our tertiary referral fertility centre between June 1998 and June 2017 for achieving fatherhood with assisted reproductive technology treatments. RESULTS A progressive increase in the median female age was observed during the study period (32.2 years until the year 2007 and 36.9 years from the year 2012). Fifty-five out of 93 patients were treated with intracytoplasmic sperm injection (ICSI) (113 ovarian stimulations, 108 ICSI procedures). Cryopreserved ejaculated sperm was used in 28 couples, fresh sperm in 19, and thawed testicular sperm in 8 couples. Mean female age at ovarian stimulation was 37.0 ± 4.7 years. Twenty-six pregnancies resulted in a full-term birth (23% per started ovarian stimulation; 43.6% per couple) and 33 children were born. No significant differences were observed according to source of sperm (fresh, frozen, testicular) and multivariate analysis confirmed that maternal age was the only variable inversely related to the cumulative delivery rate, being five times lower (15.7%) when the female partner was ≥ 40 years (OR = 0.22, 95% CI 0.06-0.77) vs. 58.3% with younger women (p = 0.0037). CONCLUSIONS Delayed childbearing and female ageing affect ICSI outcome in couples where the male is a survivor of haematological cancer. This topic should be discussed when counselling male cancer patients about fertility preservation.

Abstract
PURPOSE OF REVIEW This review aims to provide guidance to clinicians facing requests for assisted reproduction from women with mental illness. RECENT FINDINGS The paper explores the clinical and safety aspects of initiating fertility treatment in this context, including the use of psychotropic medication and the risk of untreated psychiatric mood or psychotic disorders. It also presents the ethical considerations involved in candidate selection, including treating similar cases equitably to avoid biased decisions based solely on "gut-feelings," respect for women's reproductive autonomy, and an effort to protect patients and prospective fetuses/children from harm by employing optimal strategies regarding medication and psychosocial support. Clinicians ought to be informed regarding recent evidence related to the safety and efficacy of psychopharmacologic treatment of women during pregnancy and the post-partum. They should also carry out a thoughtful ethical analysis to ensure minimal violation of women's reproductive autonomy.

Abstract
Background While their incidence is on the rise, twin pregnancies are associated with risks to the mothers and their babies. This study aims to investigate the likelihood of adverse neonatal outcomes of twins following assisted reproductive technology (ART) compared to non-ART twins. Methods A retrospective population study using the Australian National Perinatal Data Collections (NPDC) which included 19,662 twins of ≥20 weeks gestational age or ≥ 400 g birthweight in Australia. Maternal outcomes and neonatal outcomes (preterm birth, low birth weight, resuscitation and neonatal death) were compared. Generalized Estimating Equations were used to assess the likelihood of any neonatal outcomes, with adjusted odds ratio (AOR) and 95% confidence intervals (CI) presented. Weinberg’s differential rule was used to estimate monozygotic twin rate. Results ART mothers were 3.3 years older than non-ART mothers. The rates of pregnancy-induced hypertension and gestational diabetes were significantly higher for ART mothers than non-ART mothers (12.2% vs. 8.4%, p < 0.01) and (9.7% vs. 7.5%, p < 0.01) respectively. The incidence of monozygotic twins was 2.0% for ART twins and 1.1% for non-ART twins. Compared with non-ART twins, ART twins had higher rates of preterm birth (AOR 1.13, 95% CI: 1.05–1.22), low birth weight (AOR 1.13, 95% CI: 1.05–1.22), and resuscitation (AOR 1.26, 95% CI: 1.17–1.36). Liveborn ART twins had 28% (AOR 1.28, 95% CI 1.09–1.50) increased odds of having any adverse neonatal outcome compared to liveborn non-ART twins, especially for opposite-sex ART twins (AOR 1.42, 95% CI 1.11–1.82). Conclusion As ART twins had higher rates of adverse outcome, special prenatal care is recommended. Couples accessing ART should be fully informed of the risk of adverse outcome of twin pregnancies.

Abstract
Assisted reproductive technology has evolved tremendously since the emergence of in vitro fertilization (IVF). In the course of the recent decade, there have been significant efforts in order to minimize multiple gestations, while improving percentages of singleton pregnancies and offering individualized services in IVF, in line with the trend of personalized medicine. Patients as well as clinicians and the entire IVF team benefit majorly from 'knowing what to expect' from an IVF cycle. Hereby, the question that has emerged is to what extent prognosis could facilitate toward the achievement of the above goal. In the current review, we present prediction models based on patients' characteristics and IVF data, as well as models based on embryo morphology and biomarkers during culture shaping a complication free and cost-effective personalized treatment. The starting point for the implementation of prediction models was initiated by the aspiration of moving toward optimal practice. Thus, prediction models could serve as useful tools that could safely set the expectations involved during this journey guiding and making IVF treatment more effective. The aim and scope of this review is to thoroughly present the evolution and contribution of prediction models toward an efficient IVF treatment.

Abstract
Implantation failure is a major problem in human assisted reproduction, which persists regardless the optimization of endometrial receptivity and selection of genetically and morphologically healthy embryos. Since embryo-endometrium interaction depends on cell junctional, cell adhesion and cell-substratum adhesion molecules, the present study inquired whether in vitro growing murine embryos display similar to the in vivo growing embryos patterns of adhesion molecules. To this extend aVb3 expression and distribution in zygotes and 2-cell stage embryos were studied. The results demonstrated that only the in vivo growing embryos displayed specifically polarized aVb3 distribution, indicating their potential successful interaction with endometrium. Based on previous studies showing that L-carnitine (L-Cn) could affect embryonic development, it was demonstrated that the addition of L-Cn to the culture medium, could lead the in vitro growing embryos to acquire aVb3 expression and distribution similar to the in vivo growing embryos. Visualization of the effect of L-Cn using third harmonic generation imaging showed decreased lipid droplet levels in 2-cell-stage embryos, observation that correlates with an active energetic state of the growing embryos. Thus, the application of L-Cn to the culture medium could assist pre-implantation-state embryos to acquire aVb3 expression and distribution similar to the in vivo developing conditions.

Abstract
Hearing impairment (HI) caused by mutations in the connexin-26 gene (GJB2) accounts for the majority of cases with inherited, nonsyndromic sensorineural hearing loss. Due to the illegality of the abortion of deaf fetuses in Islamic countries, preimplantation genetic diagnosis (PGD) is a possible solution for afflicted families to have a healthy offspring. This study describes the first use of PGD for GJB2 associated non-syndromic deafness in Iran. GJB2 donor splicing site IVS1+1G>A mutation analysis was performed using Sanger sequencing for a total of 71 Iranian families with at least 1 deaf child diagnosed with non-syndromic deafness. In Vitro Fertilization (IVF) was performed, followed by PGD for a cousin couple with a 50% chance of having an affected child. Bi-allelic pathogenic mutations were found in a total of 12 families (~17 %); of which a couple was a PGD volunteer. The deaf woman in this family was homozygous and her husband was a carrier of the IVS1+1G>A gene mutation. Among 8 biopsied embryos, two healthy embryos were implanted which resulted in a single pregnancy and subsequent birth of a healthy baby boy. This is the first report of a successful application of PGD for hearing loss in Iran. Having a baby with a severe hearing impairment often imposes families with long-term disease burden and heavy therapy costs. Today PGD has provided an opportunity for high-risk individuals to avoid the birth of a deaf child.

Abstract
RATIONALE Couples worldwide are seeking treatment for infertility in growing numbers. Both infertility and its treatment are stressful experiences that generate considerable emotional distress. There is speculation that women's distress is associated with poorer likelihood of pregnancy via assisted reproductive technology (ART) and plausible psychobiological mechanisms bolster this association, although prior reviews of existing evidence find little support. A rigorous, comprehensive, and up to date analysis of research on the association of women's distress with ART outcomes is imperative. OBJECTIVE We systematically searched for and analyzed evidence regarding the association of women's distress before and during treatment with the likelihood of treatment success via ART. METHOD Meta-analysis using a random-effects model was conducted on prospective studies (k = 20) that compared levels of anxiety, depressive symptoms, or perceived stress before or during ART treatment in women who achieved successful pregnancy outcomes versus those who did not (total N = 4308). RESULTS Anxiety, depressive symptoms, or perceived stress pre-treatment, and anxiety or depressive symptoms during treatment, were not associated with less favorable ART outcomes. Prior treatment experience, age, and duration of infertility were not significant moderators of these associations. No eligible studies examined perceived stress during treatment. CONCLUSION Results cast doubt on the belief that distress impedes the success of infertility treatment, offering hope and optimism to the many women who feel emotionally responsible for the outcome of ART and informing the evidence-based practices of their health-care providers. We also identify specific areas and research methods needed to corroborate and extend study conclusions, including study of factors that elevate or attenuate distress in women undergoing infertility treatment.

Abstract
Background Assisted reproductive technology (ART) has been associated with low birth weight of fresh embryo transfer (FRESH) derived and increased birth weight of frozen embryo transfer (FET)-derived newborns. Owing to that, we focused on imprinted insulin-like growth factor 2 (IGF2)/H19 locus known to be important for normal growth. This locus is regulated by H19 imprinting control region (ICR) with seven binding sites for the methylation-sensitive zinc finger regulatory protein (CTCF). A polymorphism rs10732516 G/A in the sixth binding site for CTCF, associates with a genotype-specific trend to the DNA methylation. Due to this association, 62 couples with singleton pregnancies derived from FRESH (44 IVF/18 ICSI), 24 couples from FET (15 IVF/9 ICSI), and 157 couples with spontaneously conceived pregnancies as controls were recruited in Finland and Estonia for genotype-specific examination. DNA methylation levels at the H19 ICR, H19 DMR, and long interspersed nuclear elements in placental tissue were explored by MassARRAY EpiTYPER (n = 122). Allele-specific changes in the methylation level of H19 ICR in placental tissue (n = 26) and white blood cells (WBC, n = 8) were examined by bisulfite sequencing. Newborns' (n = 243) anthropometrics was analyzed by using international growth standards. Results A consistent trend of genotype-specific decreased methylation level was observed in paternal allele of rs10732516 paternal A/maternal G genotype, but not in paternal G/maternal A genotype, at H19 ICR in ART placentas. This hypomethylation was not detected in WBCs. Also genotype-specific differences in FRESH-derived newborns' birth weight and head circumference were observed (P = 0.04, P = 0.004, respectively): FRESH-derived newborns with G/G genotype were heavier (P = 0.04) and had larger head circumference (P = 0.002) compared to newborns with A/A genotype. Also, the placental weight and birth weight of controls, FRESH- and FET-derived newborns differed significantly in rs10732516 A/A genotype (P = 0.024, P = 0.006, respectively): the placentas and newborns of FET-derived pregnancies were heavier compared to FRESH-derived pregnancies (P = 0.02, P = 0.004, respectively). Conclusions The observed DNA methylation changes together with the phenotypic findings suggest that rs10732516 polymorphism associates with the effects of ART in a parent-of-origin manner. Therefore, this polymorphism should be considered when the effects of environmental factors on embryonic development are studied.

Abstract
OBJECTIVE To evaluate the efficiency of spermatozoa cryopreservation and to compare the clinical pregnancy outcomes in intracytoplasmic sperm injection (ICSI) using fresh versus cryopreserved spermatozoa collected by testicular sperm aspiration (TESA). METHODS A retrospective study was performed to compare the outcomes of men who accepted frozen-spermatozoa-based TESA-ICSI with those of men who underwent TESA-ICSI using fresh spermatozoa between January 1, 2015, and December 30, 2016. The groups were matched for age. The rates of fertilization, good-quality embryos, blastocyst formation, and clinical pregnancy outcomes were obtained from clinical records and were compared between the groups. RESULTS There were no significant differences between the frozen TESA group (n=79) and the fresh TESA group (n=194) in the rates of fertilization (71.4% vs 73.4%), good-quality embryos (55.3% vs 54.5%), blastocyst formation (60.9% vs 60.1%), clinical pregnancy (61.7% vs 55.1%), and live delivery (51.1% vs 45.7%) (P>0.05 for all comparisons). CONCLUSION Freezing low-count sperm collected by TESA with a cryoprotectant was an efficient method in the treatment of male factor infertility.

Abstract
BACKGROUND To elucidate the impact of fertility treatment on neonatal respiratory outcomes and amniotic lamellar body counts (LBCs) in twin pregnancies. METHODS One hundred ninety twin pairs, including 99 dichorionic twin (DCT) and 91 monochorionic twin (MCT) pairs were registered at our institutions. All amniotic fluid samples were obtained from each sac at cesarean section. Samples were analyzed immediately after arrival at the laboratory without centrifugation. We divided the patients into 3 groups: the no therapy group (natural conception), the induced ovulation group (with or without intrauterine insemination), and the assisted reproductive technology (ART) group (in vitro fertilization or intracytoplasmic sperm injection). RESULTS No statistically significant associations between the fertility treatment and the rates of neonatal RDS/TTN were observed in the whole study population (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.45-2.00), DCT (OR, 0.86; 95%CI, 0.30-2.47), and MCT (OR, 1.45; 95%CI, 0.41-5.11). In addition, there was no association between the fertility treatment and neonatal RDS/TTN in the propensity score analysis of the whole study population (OR, 1.25; 95%CI, 0.57-2.74). CONCLUSIONS None of the individual types of fertility treatment had a direct impact on respiratory disorders such as RDS and TTN in twin infants.
