An endometrium of type C along with an endometrial thickness of < 8 mm are risk factors for ectopic pregnancy after stimulated cycles with fresh embryo transfer. BMC Pregnancy Childbirth 2023; 23:713. [PMID: 37803277 PMCID: PMC10557322 DOI: 10.1186/s12884-023-05920-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 08/14/2023] [Indexed: 10/08/2023] Open
Abstract
BACKGROUND The study investigated whether specific ultrasonographically observed endometrial features (including endometrium type and thickness) were linked to ectopic pregnancy after stimulated cycles with fresh embryo transfer. METHOD Of 6246 pregnancy cycles after fresh embryo transfer, 6076 resulted in intrauterine pregnancy and 170 in ectopic pregnancy. The primary outcome of the study was ectopic pregnancy, with the main variables being endometrium type and endometrial thickness. Univariate and subsequent multiple-stepwise logistic regression analyses were used to identify the risk factors of ectopic pregnancy. RESULTS 1. Compared with patients with an endometrial thickness ≥ 8 mm, the adjusted odds ratio for those with an endometrial thickness < 8 mm was 3.368 (P < 0.001). The adjusted odds ratio for women with a type-C endometrium was 1.897 (P = 0.019) compared with non-type C. 2. A larger dose of gonadotropin used during controlled ovarian hyperstimulation was a protective factor against ectopic pregnancy (P = 0.008). 3. The GnRH antagonist protocol (P = 0.007) was a risk factor for ectopic pregnancy, compared with the use of GnRH agonists. CONCLUSION (1) An endometrial thickness < 8 mm coupled with a type C endometrium significantly increased the risk of ectopic pregnancy after fresh embryo transfer. (2) A thin endometrial thickness and a type C endometrium could be further related to an abnormal endometrial receptivity/peristaltic wave. (3) Patients at a high risk of ectopic pregnancy should therefore be given special attention, with early diagnosis during the peri-transplantation period may assist in the prevention of ectopic pregnancy.

Abstract
The prevalence of infertility and the use of assisted reproductive treatment (ART) have been increasing worldwide in recent years. It appeared relevant to conduct a literature review on the safety of these techniques regarding the neurodevelopment and mental health of children and adolescents especially after in vitro fertilization. ART represents obstetrical risk factors. However, the published results are reassuring on the neurodevelopmental level as well as on the cognitive, psychomotor and language levels and on the behavioral and emotional levels among children and adolescents resulting from ART.

Association between a morphokinetic ploidy prediction model risk score and miscarriage and live birth: a multicentre cohort study. Fertil Steril 2023; 120:834-843. [PMID: 37307891 DOI: 10.1016/j.fertnstert.2023.06.006] [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: 02/24/2023] [Revised: 05/31/2023] [Accepted: 06/05/2023] [Indexed: 06/14/2023]
Abstract
OBJECTIVE To determine whether the aneuploidy risk score from a morphokinetic ploidy prediction model, Predicting Euploidy for Embryos in Reproductive Medicine (PREFER), is associated with miscarriage and live birth outcomes. DESIGN Multicentre cohort study. SETTING Nine in vitro fertilization clinics in the United Kingdom. PATIENTS Data were obtained from the treatment of patients from 2016-2019. A total of 3587 fresh single embryo transfers were included; preimplantation genetic testing for aneuploidy) cycles were excluded. INTERVENTION PREFER is a model developed using 8,147 biopsied blastocyst specimens to predict ploidy status using morphokinetic and clinical biodata. A second model using only morphokinetic (MK) predictors was developed, P PREFER-MK. The models will categorize embryos into the following three risk score categories for aneuploidy: "high risk," "medium risk," and "low risk." MAIN OUTCOME MEASURES The primary outcomes are miscarriage and live birth. Secondary outcomes include biochemical clinical pregnancy per single embryo transfer. RESULTS When applying PREFER, the miscarriage rates were 12%, 14%, and 22% in the "low risk," "moderate risk," and "high risk" categories, respectively. Those embryos deemed "high risk" had a significantly higher egg provider age compared with "low risk," and there was little variation in risk categories in patients of the same age. The trend in miscarriage rate was not seen when using PREFER-MK; however, there was an association with live birth, increasing from 38%-49% and 50% in the "high risk," "moderate risk," and "low risk" groups, respectively. An adjusted logistic regression analysis demonstrated that PREFER-MK was not associated with miscarriage when comparing "high risk" to "moderate risk" embryos (odds ratio [OR], 0.87; 95% confidence interval [CI], 0.63-1.63) or "high risk" to "low risk" embryos (OR, 1.07; 95% CI, 0.79-1.46). An embryo deemed "low risk" by PREFER-MK was significantly more likely to result in a live birth than those embryos graded "high risk" (OR, 1.95; 95% CI, 1.65-2.25). CONCLUSION The PREFER model's risk scores were significantly associated with live births and miscarriages. Importantly, this study also found that this model applied too much weight to clinical factors, such that it could no longer rank a patient's embryos effectively. Therefore, a model including only MKs would be preferred; this was similarly associated with live birth but not miscarriage.

Abstract
OBJECTIVE To evaluate live-birth rates per embryo transfer in patients with uterine Müllerian anomalies (UMAs). Secondary objectives were to compare reproductive outcomes between the normal uterus group, the different UMA types, and UMA subgroups with and without required surgery. DESIGN This retrospective study compared two cohorts, one with UMAs and other with normal uteri of our oocyte donation program at 12 Instituto Valenciano De Infertilidad/Reproductive Medicine Associates University affiliated clinics from January 2000 to 2020. The oocyte donation reduces confounding because of differences in embryo quality. The primary outcome was the live-birth rate per embryo transfer. Secondary outcomes included the rates of implantation, clinical pregnancy, miscarriage, and ongoing pregnancy. We calculated odds ratios with 95% confidence intervals. PATIENTS Infertile women undergoing oocyte donation with UMAs. INTERVENTION None. MAIN OUTCOME MEASURES The rates of implantation, clinical pregnancy, miscarriage, ongoing pregnancy, and live birth. RESULTS We analyzed 58,337 cycles of oocyte donation: 57,869 patients had no uterine malformation, and 468 women had UMAs. Compared with patients with normal uteri, patients with UMAs had lower rates of live births (36.67% [32.84-40.65] vs. 38.1% [95% confidence intervals {CI}: 37.82-38.42]) and ongoing pregnancy (39.74% [35.93-43.66] vs. 41.5% [41.24-41.83]). The miscarriage rate was higher in patients with UMAs (19.5% [16.55-22.85] vs. 16.6% [16.47-16.92]). Specifically, patients with a unicornuate uterus (n=29) had lower rates of implantation (24.07% [13.49-37.64] vs. 42.85% [95% CI: 42.6-43.09]), pregnancy (41.86% [27.01-57.87] vs. 59.51% [59.22-59.81]), ongoing pregnancy (16.67% [6.97-31.36] vs. 41.54% [41.24-41.83]), and live births (16.67% [6.97-31.36] vs. 38.12% [37.83-38.42]). In addition, patients with a partial septate uterus (n=91) had a higher miscarriage rate (26.50% [18.44-34.89] vs. 16.7% [16.47-16.92]). Compared with the normal uterus group, the live-birth rates were lower in the UMA without surgery group (33.09% [27.59-38.96] vs. 38.12% [37.83-38.42]). CONCLUSION Among patients who received embryos derived from donated oocytes, live birth and ongoing pregnancy rates were lower in patients with UMAs compared with patients with normal uteri. A higher miscarriage rate was found in patients with UMAs. Patients with a unicornuate uterus had worse reproductive outcomes. Our results show that the uterus is less competent in patients with UMAs. TRIAL REGISTRATION This study was registered at clinicaltrial.gov (NCT04571671).

Abstract
PURPOSE Several studies indicate that assisted reproductive technology (ART) including in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) pregnancies carries increased risk of complications including postpartum hemorrhage (PPH). However, the association between IVF/ICSI and the bleeding risk particularly in cesarean delivery has not been systematically assessed. The aim of this study was to evaluate bleeding risk during and after cesarean delivery in parturients who conceived using IVF or ICSI. METHODS This is a retrospective observational study analyzing data from 310 parturients who underwent cesarean delivery: 155 who had conceived using IVF or ICSI (IVF/ICSI group) and 155 age and year of delivery matched controls who had conceived spontaneously (control group). The primary outcome measure was the amount of blood lost during and within 24 h after cesarean delivery. Secondary outcome measure was the incidence of severe PPH. With 132 parturients in each group, we had 90% power to detect a 200 mL difference in the bleeding amount, at a 0.05 two-sided significance level. RESULTS The amount of bleeding in the IVF/ICSI group was 1234 ± 669 mL, which was 124 mL (11.2%) greater than that in the control group (95% CI - 34 to 282; p = 0.12). The incidence of severe PPH in the IVF/ICSI group and in the control group was 23.9% and 16.8%, respectively (p = 0.16), and the unadjusted odds ratio was 1.6 (95% CI, 0.9-2.7; p = 0.12). No significant independent effect of IVF/ICSI on the bleeding amount and the incidence of severe PPH was observed in multivariable regression analyses (p = 0.22, p = 0.16). CONCLUSION In this study, IVF and ICSI were not associated with increasing risk of bleeding in cesarean delivery.

Abstract
Background Intrauterine adhesions (IUA), arising from diverse etiological factors, pose a significant threat to female fertility, particularly during in vitro fertilization (IVF) treatment. Objective To assess the effectiveness of hysteroscopic adhesiolysis (HA) combined with periodic balloon dilation in treating IUA and its impact on reproductive outcomes in women undergoing IVF treatment. Methods A total of 234 patients diagnosed with IUA were included in this study. The IUA women were categorized into three subgroups based on the severity of adhesion. All IUA patients underwent HA separation followed by periodic balloon dilation along with hormone replacement therapy (HRT). Frozen embryo transfer was performed post-treatment, and a comparative analysis of the general characteristics and clinical outcomes among the subgroups was conducted. The control group consisted of patients who underwent their first embryo transfer of HRT cycle without any uterine abnormalities, as assessed by the propensity score matching (PSM). The clinical outcomes of IUA group and control group were compared. Multivariate logistic regression analyses were employed to investigate the risk factors associated with live birth. Results ① The endometrial thickness was significantly increased post-operation compared to pre-operation in all three IUA subgroups (all P <0.001), with the most pronounced change observed in the severe IUA group. After treatment, normal uterine cavity was restored in 218 women (93.16%). ② The overall clinical pregnancy rate was 49.57% (116/234) and live birth rate was 29.91% (70/234). The clinical outcomes were similar among the three subgroups after first embryo transfer (all P>0.05). Multivariate logistic regression analyses revealed that age (aOR 0.878, 95% CI 0.817~0.944, P=0.001) and endometrial thickness after treatment (aOR 1.292, 95% CI 1.046~1.597, P=0.018) were the two significant risk factors for live birth rate. ③ Following the process of matching, a total of 114 patients were successfully enrolled in the control group. The baselines and the clinical outcomes were all comparable between the IUA group and control group (all P>0.05). Conclusion The combination of HA and periodic balloon dilation is beneficial for improving endometrial receptivity and has a significant clinical impact on patients with IUA undergoing IVF.

Abstract
Background ICSI (intracytoplasmic sperm injection) leads to a reduced male-to-female ratio at birth, whereas blastocyst transfer results in an increased male-to-female ratio. However, limited knowledge exists regarding the impact of these factors on the live birth rate for each gender. This study aimed to investigate the influence of patient characteristics and treatment parameters on the live birth rate for each gender, as well as the ultimate male-to-female ratio at birth in frozen-thawed embryo transfer (FET) cycles. Method This retrospective cohort study involved a total of 28,376 FET cycles and 9,217 subsequent deliveries, spanning from January 2003 to December 2015. The study consisted of two parts. First, logistic regression models were constructed to determine the factors influencing the male-to-female ratio among babies born after FET. Second, we aimed to investigate the mechanisms underlying this sex ratio imbalance by analyzing data from all transfer cycles. Generalized estimated equations were employed to assess the impact of risk factors on rates of male and female live births separately. Results ICSI resulted in a lower proportion of male offspring compared to in vitro fertilization (IVF) (50.1% vs. 53.7%, aOR: 0.87, 95% CI: 0.80-0.96). Conversely, blastocyst transfer yielded a higher proportion of male offspring than cleavage-stage embryo transfer (58.7% vs. 51.6%, aOR: 1.32, 95% CI: 1.17-1.48). Analysis of all cycles indicated that ICSI resulted in a reduced likelihood of male live birth in comparison to IVF (19.8% vs. 21.6%, aOR: 0.90, 95% CI: 0.83-0.97). However, the transfer of blastocysts rather than cleavage-stage embryos not only increased the chance of male live birth (26.9% vs. 20.2%, aOR: 1.70, 95% CI:1.56-1.85) but also facilitated female live birth (20.3% vs. 19.3%, aOR: 1.26, 95% CI: 1.15-1.39). Conclusion ICSI was associated with a reduction in the male-to-female sex ratio and a lower rate of male live births, while blastocyst transfer was associated with an increased male-to-female sex ratio at birth and a higher rate of male live births.

Abstract
Ovarian hyperstimulation syndrome (OHSS) is the main severe complication of ovarian stimulation for in vitro fertilization (IVF) cycles. The aim of the current study was to identify the interventions for the prevention of and reduction in the incidence and severity of OHSS in patients who undergo IVF not included in systematic reviews with meta-analyses of randomized controlled trials (RCTs) and assess and grade their efficacy and evidence base. The best available evidence for each specific intervention was identified, analyzed in terms of safety/efficacy ratio and risk of bias, and graded using the Oxford Centre for Evidence-Based Medicine (CEBM) hierarchy of evidence. A total of 15 interventions to prevent OHSS were included in the final analysis. In the IVF population not at a high risk for OHSS, follitropin delta for ovarian stimulation may reduce the incidence of early OHSS and/or preventive interventions for early OHSS. In high-risk patients, inositol pretreatment, ovulation triggering with low doses of urinary hCG, and the luteal phase administration of a GnRH antagonist may reduce OHSS risk. In conclusion, even if not supported by systematic reviews with homogeneity of the RCTs, several treatments/strategies to reduce the incidence and severity of OHSS have been shown to be promising.

Abstract
Introduction The failure of remodeling the spiral arteries is associated with the pathogenesis of preeclampsia. Estradiol (E2) plays a crucial role in placentation and may be involved in the development of preeclampsia. However, there is a lack of data in this area. This study aims to assess the association between serum estradiol levels in early pregnancy and the risk of preeclampsia. Methods We conducted a retrospective cohort study on patients who conceived after frozen embryo transfer (FET) using data from a database at a university-affiliated in vitro fertilization center. The study period spanned from January 1, 2010, to December 31, 2020. Multivariable logistic regression analyses were performed to determine the adjusted effect of E2 levels on the risk of preeclampsia. We compared the odds ratios of preeclampsia across quartiles of E2 levels and assessed their significance. Results Serum E2 levels at the fifth gestational week were significantly different between women with and without preeclampsia after FET programmed cycles (607.5 ± 245.4 vs. 545.6 ± 294.4 pg/ml, p=0.009). A multivariable logistic regression model demonstrated that E2 levels in early pregnancy were independent risk factors for preeclampsia. We observed an increased odds ratio of preeclampsia with increasing quartiles of estradiol levels after adjusting for potential confounders in FET programmed cycles. When comparing quartiles 3 and 4 (E2 > 493 pg/ml at the fifth gestational week) to quartiles 1 and 2, the odds ratios of preeclampsia were significantly higher. Conclusion We found that serum E2 levels in early pregnancy may impact the risk of preeclampsia, particularly following FET programmed cycles. The association between E2 levels in early pregnancy and preeclampsia deserves further investigation.

Abstract
Objective To investigate the association between female body mass index (BMI) and live birth rates and maternal and perinatal outcomes after in-vitro fertilization (IVF). Methods We performed a national, population-based cohort study including women undergoing IVF between 2002 and 2020. The cohort included 126,620 fresh cycles and subsequent frozen embryo transfers between 2007 and 2019 (subpopulation 1) and 58,187 singleton deliveries between 2002 and 2020 (subpopulation 2). Exposure was female BMI (kg/m2) categorized according to the World Health Organization as underweight (<18.5), normal weight (18.5-24.9, reference), overweight (25.0-29.9), class I obesity (30.0-34.9), class II obesity (35.0-39.9), and class III obesity (≥40.0). The primary outcome in subpopulation 1 was cumulative live birth per started fresh IVF cycle, including fresh and subsequent frozen embryo transfers. Primary outcomes in subpopulation 2 were hypertensive disorders of pregnancy and preterm birth at less than 37 weeks. Risk ratios (RRs) with 95% confidence intervals (CIs) for the association between BMI class and outcomes were calculated using generalized linear models after adjustment for relevant confounders. Results The cumulative live birth rate decreased significantly with increasing BMI from 32.6% in normal-weight women to 29.4% in overweight women, 27.0% in women in obesity class I, 21.8% in women in obesity class II, and 7.6% in women in obesity class III. The risk of hypertensive disorders of pregnancy increased significantly and progressively with increasing BMI, from 4.6% in normal-weight women to 7.8% in overweight women and 12.5%, 17.9%, and 20.3% in women in obesity classes I, II, and III. The risk of preterm birth followed a similar pattern, from 6.3% in normal-weight women to 7.5% in overweight women and 8.9%, 9.9%, and 15.3% in women in obesity classes I, II, and III. The risks of other perinatal complications, such as perinatal death, showed an even more pronounced increase. Conclusion Using a large and complete national cohort of women undergoing IVF, we demonstrate a dose-dependent decrease in live birth rate and a substantial increase in maternal and perinatal complications with increasing BMI. Strategies to improve this situation are warranted.

Abstract
PURPOSE To compare perinatal outcomes in in-vitro fertilization (IVF) pregnancies versus spontaneous conceptions in woman of advanced maternal age (AMA), and to evaluate the effect of increasing age on IVF pregnancies' outcomes. METHODS A retrospective population-based cohort study including pregnant women who delivered between 2008-2014 in the US. First, we included women aged 38-43 years and compared those with IVF conceptions (cases) to women with spontaneous conceptions (controls). Thereafter, we compared IVF pregnancies in women aged 38-43 years to IVF pregnancies at < 38 years of age. Multivariate logistic regression was performed to compare both groups regarding pregnancy,delivery, and neonatal outcomes after adjusting for plausible confounders. RESULTS Three hundred nine thousand five hundred sixty-seven pregnant women aged 38-43 years were identified, with 2,762 composing the IVF group, and 306,805 composing the control group. After adjusting for confounders, the IVF group had a higher risk of several adverse obstetrical outcomes, including hypertensive disorders of pregnancy (aOR 1.31,95%CI 1.06-1.62), gestational diabetes (aOR 1.26,95%CI 1.13-1.41),preterm delivery (aOR 1.45,95%CI 1.16-1.81), cesarean section (CS) (aOR 1.84,95%CI 1.55- 2.19),postpartum hemorrhage (aOR 1.68,95%CI 1.27- 2.24), and maternal infection (aOR 1.90,95%CI 1.31-2.77), with comparable neonatal outcomes. For the second analysis, 9712 IVF pregnancies were included (n = 6950 < 38 years, and n = 2762 ≥ 38 years). Women ≥ 38 years who underwent IVF were more likely to experience hypertensive disorders of pregnancy, CS, hysterectomy and blood transfusion, with comparable neonatal outcomes. CONCLUSION IVF AMA pregnancies have a significant increase in myriad perinatal complications compared to spontaneous AMA pregnancies. Younger women undergoing IVF have mildly less complications than their older counterparts.

Abstract
Interleukin-12 (IL-12) is involved in the occurrence and development of many diseases, such as preeclampsia, intrauterine growth restriction, preterm labor, and recurrent pregnancy losses. This study aimed to determine whether a high serum level of IL-12 was associated with adverse in vitro fertilization (IVF) outcomes. Included infertile women with high serum IL-12 levels who underwent IVF cycles and infertile controls with pure tubal etiology. The impact of serum IL-12 on baseline and clinical characteristics, immune-related indicators, IVF laboratory, and pregnancy outcomes were compared. In addition, the correlation of follicular fluid IL-12 and serum IL-12 level and the role of IL-12 in apoptosis of granulosa cells (GCs) was investigated. Women with high serum IL-12 levels had lower numbers of retrieved oocytes, embryos, perfect and available embryos, lower rates of perfect and available embryos, and blastocyst formation. Additionally, significantly higher levels of serum Th1, Th2, and Th17-related cytokines were observed in women with high serum IL-12 levels than in the controls. Meanwhile, the follicular fluid IL-12 levels were positively correlated with serum IL-12 levels, and IL-12 promoted apoptosis of GCs in vitro. We concluded that women with serum high IL-12 levels may have adverse IVF outcomes, partly by promoting apoptosis of GCs. Therefore, early screening for cytokines, especially IL-12, and appropriate consultation for couples receiving IVF-ET should be considered. In addition, specific immune and inflammatory mechanisms associated with high serum IL-12 levels should be further explored.

Abstract
Infertility is defined as inability to conceive despite regular unprotected sexual intercourse for greater than 1 year. Conditions involving the male partner accounts for the infertility in approximately 50% of cases. The goals of imaging in male infertility are to detect treatable/ reversible causes, imaging for sperm retrieval from testis or epididymis for assisted reproductive techniques like in vitro fertilization or intracytoplasmic sperm injection and to provide appropriate genetic counselling for prevention of occurrence of disease in future offspring. The purpose of this article is to describe imaging features in various causes of male infertility to acquaint radiologists with various imaging appearances of causes of male infertility to avoid missing these pathologies.

Abstract
OBJECTIVE Endometrial polyps (EPs) are one of the most common pathologies detected during the examination of the uterine cavity of infertile women. We aimed to demonstrate the relationship between EPs, chronic endometritis (CE) and in vitro fertilization (IVF) outcomes. PATIENTS AND METHODS This retrospective study was performed on 394 hysteroscopically examined infertility cases. We performed polyp resections (PR) and extensive biopsies of the endometrium to demonstrate the association with clinical pregnancy (CP) by IVF. We performed statistical analysis to compare these associations. RESULTS The incidence of CE was twice as high in the presence of EPs as in the absence of EPs. The associations between EPs and PR were found to be significant for positive CP outcomes. A significant difference in IVF outcome was found between the group with EPs and the group without EPs. All these associations were statistically significant (p < 0.05). CONCLUSIONS We found a frequent association between EPs and CE. The pregnancy rate obtained after IVF was negatively affected by the presence of EPs. Treatment of these pathologies improved IVF outcomes.

Abstract
This study compared the pregnancy and neonatal outcomes between fresh embryo transfer and frozen-thawed embryo transfer (FET). These patients were split into two groups: the fresh embryo transfer group and the FET group. The general conditions, pregnancy outcomes, and neonatal outcomes between these groups were compared. The influencing factors of fetal macrosomia occurrence were explored as well. Compared with the fresh embryo transfer group, the FET group had a significantly higher mean age (32.59 ± 4.77 vs. 31.90 ± 4.71, p < 0.05) and lower multiple pregnancy rate (21.2% vs. 26.9%, p < 0.05). There was no significant difference in the incidence of congenital anomalies of neonates between the two groups (1.32% vs. 0.37%, p > 0.05). In the FET group, compared with the fresh embryo transfer group, the mean birth weight of singleton live births, the cesarean section rate, and the incidence of fetal macrosomia were significantly increased, while the incidence of low birth weight was significantly decreased. The logistic analysis showed that the occurrence of fetal macrosomia was primarily associated with the embryo transfer protocol (odds ratio [OR] = 2.769, 95% confidence interval [CI]: 1.246-6.154, p < 0.05), endometrial thickness (OR = 1.144, 95% CI: 1.043-1.256, p < 0.05), and gestational age (OR = 1.710, 95% CI: 1.338-2.184, p < 0.05). Macrosomia (OR = 2.938, 95% CI: 1.436-6.010, p = 0.003) and multiple pregnancy (OR = 3.574, 95% CI: 2.616-4.882, p < 0.001) significantly increased the cesarean section rate. The risk of fetal macrosomia and congenital anomalies in the offspring of the fresh embryo transfer group was lower than that in the offspring of the FET group, we preferred to fresh embryo transfer for patients with assisted reproductive technologies. FET should be used as supplementary therapeutic strategy with strengthened pregnancy management and screening to reduce the occurrence of birth defects in newborns.

Abstract
There have been concerns on the potential overuse of in vitro fertilization (IVF) in view of the lack of evidence on effectiveness in certain populations, potential short and long-term safety risks, and economic considerations. On the other hand, the use of alternatives to IVF seems to be underappreciated in clinical practice as well as research. In this review, we summarized the up-to-date evidence on the effectiveness, safety as well as cost-effectiveness of different alternatives to IVF, including expectant management, intrauterine insemination, tubal flushing, in vitro maturation as well as intravaginal culture. We also discussed the trend of IVF use over the last decade and the available tiers of service because of intravaginal culture, and revisited the roles of different alternatives to IVF in modern reproductive medicine from both clinical and research perspectives.

Abstract
OBJECTIVE To investigate the effect of women's reproductive history on live-birth rate and perinatal outcome after first frozen-thawed embryo transfer (FET) without preimplantation genetic testing for aneuploidy. METHODS This was a retrospective cohort study of women who had undergone their first FET cycle between January 2014 and December 2020 at a university-affiliated fertility center. No transferred embryo underwent preimplantation genetic testing for aneuploidy. The women were categorized into five groups based on their reproductive history: no previous pregnancy; previous termination of pregnancy (TOP); previous pregnancy loss; previous ectopic pregnancy (EP); and previous live birth. The women with no previous pregnancy were considered as the reference group. The primary outcome was the live-birth rate and secondary endpoints included rates of positive pregnancy test, clinical pregnancy, pregnancy loss and EP as well as perinatal outcomes such as birth weight and preterm birth. Multivariable logistic regression analyses were used to control for a number of potential confounders, including age, body mass index, education level, duration and cause of infertility, insemination method, type of endometrial preparation, number of embryos transferred, embryo developmental stage, quality of the embryos transferred, year of treatment and endometrial thickness. Additionally, propensity score matching (PSM) was used to check the robustness of the main findings. RESULTS In total, 25 329 women were included in the final analysis. On univariate analysis, each reproductive-history type except for previous EP was significantly associated with worse pregnancy outcome following in-vitro fertilization (IVF), including rates of positive pregnancy test, clinical pregnancy, pregnancy loss and live birth, when compared with the group of women with no previous pregnancy. However, after correcting for several potential confounders, the differences in rates of live birth, pregnancy loss, positive pregnancy test and clinical pregnancy were no longer significant between the study and control groups on multivariable regression models, while the risk of EP after embryo transfer was elevated among women with a previous TOP or EP. There was no increased risk of adverse perinatal outcome associated with reproductive history compared with the control group. Notably, similar results were obtained from the PSM models, confirming the robustness of the main findings. CONCLUSION Relative to women without a previous pregnancy, those with a prior TOP, pregnancy loss, EP or live birth did not have compromised live-birth rate or perinatal outcomes following FET without preimplantation genetic testing for aneuploidy, with the exception of an increased risk of EP in those with prior TOP or EP. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
PURPOSE To evaluate the risk of miscarriage in IVF cycles in women with PCOS. METHODS Systematic review and meta-analysis. Systematic search of MEDLINE, EMBASE and Google Scholar. The language search was restricted to English, Spanish and French, from 2000 to 2019, with crosschecking of references from relevant articles. Inclusion criteria were: (1) IVF cycles (2) a group of patients with PCOS was considered separately, (3) the miscarriage rate was reported, (4) there was a control group, (5) definition of PCOS according the Rotterdam criteria. Exclusion criteria were been excluded from the meta-analysis: (1) publication prior to the year 2000, (2) animal studies, (3) reviews, (4) abstracts or conference papers, (5) letters, (6) case reports, (7) studies comparing different IVF techniques, (8) studies comparing groups with and without metformin or other treatments, (9) studies on induced abortions. Risk of bias was assessed by the Newcastle-Ottawa score (NOS). All the included studies had a low risk of bias (NOS scores ranging 7-8). The review protocol was registered in PROSPERO (CRD42020186713). Seventeen studies were included in the meta-analysis. There was a total of 10,472 pregnancies (2650 in PCOS and 7822 in controls) of which 1885 were miscarriages (682 in PCOS and 1203 in controls). We considered the miscarriage rate (MR), preclinical MR, early MR, and late MR. RESULTS In IVF pregnancies the risk of miscarriage was significantly increased when considering miscarriages in total (RR = 1.59; CI = 1.45-1.75), preclinical miscarriages (RR = 1.59; CI = 1.35-1.88), and early miscarriages (RR = 1.44; CI = 1.16-1.79). The increased miscarriage rate persisted in Chinese and Western populations when considered separately. The risk of miscarriage was increased in the subgroup of fresh transfers (RR = 1.21; CI = 1.06-1.39) as well as in the subgroup including either fresh or frozen transfers (RR = 1.95; CI = 1.72-2.22). CONCLUSION PCOS is linked to an increased MR in IVF pregnancies both of miscarriages in total, and to an increase in preclinical and early miscarriages. PROSPERO NUMBER CRD42020186713.

Abstract
BACKGROUND Thyroid autoimmunity and polycystic ovary syndrome (PCOS) are the most common endocrinopathies and have close relationships based on common etiology and pathogenesis, including genetic susceptibility, metabolic disorders, hormonal dysregulation, immune response, and inflammatory activation. The co-occurrence of both diseases is associated with adverse reproductive outcomes, but its effect on neonatal outcomes remains largely unknown. We aim to explore the effect of thyroid autoimmunity on neonatal birth weight in PCOS women undergoing IVF/ICSI. METHODS This is a retrospective analysis of 486 PCOS women who underwent the first IVF/ICSI cycles and gave birth to 361 singletons and 125 twins during 2018 - 2020 at a reproductive center. The associations between maternal preconception serum thyroid function and autoimmunity indicators and birth weights of the singleton and twin groups were evaluated using generalized linear models (GLMs) and generalized estimate equations (GEEs), respectively. Analyses were further stratified by neonatal sex, maternal age, and maternal preconception BMI to assess the possible interaction effects. RESULTS Maternal preconception serum TPOAb had a significant negative association with singleton birth weight (P for trends = 0.03). Compared with women in the first tertile of TPOAb, women in the third tertile had a change in singleton birth weight of - 119.72 g (95% CI: - 222.68 g, - 16.70 g). Maternal preconception serum TPOAb had a significant positive association with twin birth weight (P for trends = 0.01). Compared with women in the first tertile of TPOAb, women in the third tertile had a change in twin birth weight of 138.62 g (95% CI: 33.96 g, 243.30 g). Besides, maternal preconception serum TPOAb had a specific association with increased twin birth weight for female neonates, a specific association with decreased singleton birth weight for PCOS women under 35 years, and a specific association with decreased twin birth weight for overweight PCOS women (all P for interactions < 0.05). CONCLUSIONS Maternal preconception thyroid autoimmunity may affect the birth weights of both singleton and twin neonates. Further large cohorts and experimental studies are required to confirm these findings and explore the underlying mechanisms.

Abstract
McCune-Albright syndrome (MAS) is a rare genetic disease affecting multiple organs, including endocrine tissues. This endocrinopathy is sometimes responsible for infertility, as it may induce an independent functioning of the ovaries leading to anovulatory cycles. This case report describes the infertility journey of a 22-year-old female who had early puberty and irregular periods with high estrogen and progesterone levels, low FSH and LH (on day 3 of her menstrual cycle), and a multi-cystic right ovary. She received several infertility treatments: initially in vitro oocyte maturation (IVM) followed by cyst transvaginal ultrasound-guided aspiration, all unsuccessful. A right hemi-ovariectomy was performed that eventually restored regular cycles and made it possible to perform ovarian stimulation (OS) and in vitro fertilization (IVF). Live birth was obtained after the first embryo transfer.

Abstract
Obesity is a highly prevalent chronic disease with a significant effect on reproductive-age women. The clinical implications of obesity on fertility and pregnancy are well studied citing ovulatory dysfunction, hormonal imbalances, higher miscarriage rates, and increased maternal and neonatal risks. For this reason, many patients with obesity seek reproductive specialists to help build their families. Despite this literature base, the effect of weight loss interventions prior to assisted reproductive technology (ART) is lacking. This review aims to outline the impact of obesity on ART, specifically in vitro fertilization (IVF). Response differences to treatment protocols compared with normal weight counterparts, limitations of access to care, and the mixed results of weight-reduction strategies prior to fertility treatment will be addressed. The known data surrounding benefits of lifestyle modification, pharmacologic therapies, and surgical interventions for obesity prior to IVF are outlined and found to emphasize a need for further research to determine the optimal approach for infertility patients with obesity.

Abstract
OBJECTIVE Obesity is one of the main concerns for public health and is becoming an increasingly widespread problem worldwide. Women are more likely to require a cesarean section and have a longer hospital stay after delivery. Excess body weight can interfere with ovulation and make it more difficult for embryos to implant in the uterus. A high body mass index (BMI) has controversial effects on the outcomes of medically assisted reproduction treatments (IVF) and, if careful counseling is not performed, medical-legal risks may be incurred. While some researchers argue that obesity does not particularly affect ART outcomes, other studies claim that a high BMI does not interfere with embryonic development. Both the American Society for Reproductive Medicine (ASRM) and the European Society of Human Reproduction and Embryology (ESHRE) has stated that there is no clear evidence supporting a BMI limit for IVF treatment and that each patient should be evaluated on an individual basis. The purpose of our study was to evaluate whether performing in vitro fertilization on these patients increases the risk of medical, surgical, and anesthetic complications of oocyte retrieval. PATIENTS AND METHODS From January 2011 to December 2022, all patients with BMI higher than 25 were enrolled in the study (n=766). Complications and risks related to oocyte retrieval were evaluated, and patients were divided according to BMI groups. RESULTS With the one-way ANOVA test, all groups were compared with the control group, and none showed statistically significant differences, only the number of produced embryos in the BMI group between 30-34.9 was lower and statistically significant. CONCLUSIONS Only one study has analyzed these aspects, mainly focusing on the need for anesthesia drugs and any related complications, and the same author reported greater difficulty in performing oocyte retrieval. The same study recorded an increase in incomplete oocyte retrievals. Our work does not confirm any of these impressions.

Abstract
In order to inform patients undergoing ART regarding their chances for motherhood, it seems useful to describe "freeze all" outcomes according to the different potential indications. The goal of this study was to examine the impact of a "freeze-all approach" on the cumulative live birth rate (cLBR) according to the indication. It is a cohort study including women who had undergone ovarian stimulation (OS) using an antagonist protocol with GnRH agonist triggering between 09.2016 and 09.2018 followed by a freeze-all cycle of blastocyst embryos. The ART outcomes were compared between the two main indications of the freeze-all strategy which were in our cohort: risk of ovarian hyperstimulation syndrome (OHSS) and endometriosis. The ART outcomes were also described for the others indications (inadequate endometrium and/or premature progesterone elevation at trigger day, two or more previous ART failures, and autoimmune disease and/or a high risk of thromboembolic disease (AI and/or TE risk)). In total, 658 women were included. The cLBR in the total population was 37.7% (248/658). The cLBR was significantly higher in the "OHSS risk" group (133/281, 47.3%) than in the "endometriosis" group (69/190, 36.3%) (p = 0.017). No significant differences were noted regarding perinatal outcomes, except a significantly higher risk of placenta praevia (PP) observed in the "endometriosis" group (10.1%) (p = 0.002). The "freeze-all approach" yielded good results in terms of the cLBR and especially in case of OHSS risk. These data should be taken into account when informing patients about the ART strategy and their chances of motherhood.

Abstract
OBJECTIVES Assisted Reproductive Technology (ART) has made great strides in the past forty-years, but no medical treatment comes without side effects. Despite several studies reporting high incidences of perinatal complications, the association is inconclusive. Also, the effect of racially and ethnically distinguished Asian population undergoing ART on perinatal outcomes is not well studied. Therefore, this study attempts to compare various perinatal outcome parameters in ART, and spontaneously conceived singleton pregnancies from a single high-volume tertiary care center. METHODS This is a retrospective cohort study from a single tertiary infertility center, carried out from January 2011 to September 2020. The study included 1,125 IVF conceived babies (AB group) and 7,193 spontaneous conceived babies (SB group). The groups were compared using the Pearson Chi-square test and adjusted odds ratio, calculated using the multivariate analysis. RESULTS Most of the perinatal complications, such as preterm birth (PTB), early preterm birth, low birth weight (LBW), extremely low birth weight, small for gestational age, large for gestational age babies, neonatal intensive care unit (NICU) admission, need for surfactant, meconium aspiration syndrome, neonatal seizures, intraventricular hemorrhage, hypoxic-ischemic encephalopathy, and patent ductus arteriosus was significantly increased in the AB group when compared to the SB group (p<0.05). In-vitro fertilization (IVF) independently increases the risk of LBW (aOR 2.530; 95% CI 2.194-2.917), PTB (aOR 4.004; 95% CI 3.496-4.587), NICU admission (aOR 2.003; 95% CI 1.610-2.492) and neonatal seizures (aOR 9.805; 95% CI 5.755-16.706).Conclusions: All ART-conceived pregnant patients should receive antenatal counselling regarding perinatal complications and should deliver at a tertiary care center with appropriate NICU support.

Abstract
AIM This study aims to systematically review the current literature on published studies with data on the clinical significance of endometrial thickness on ultrasound for live birth rates after IVF or intracytoplasmic sperm injection (ICSI). METHODS An extensive systematic review of PubMed, Web of Science, ScienceDirect, Google Scholar, and Open Gray databases, and following hand-search of the reference list of the included studies was performed. RESULTS We found 20 eligible studies that evaluated 20 546 patients for endometrial thickness, presented risk factors for decreased endometrial receptivity, and IVF outcomes with fresh and frozen embryo transfer (FET) cycles. The mean age of the patients ranged from 28.86 to 41.03 years. Reported endometrial thickness ranged from <4 mm to >15 mm. The clinical pregnancy rate varied from 9,09% to 61,49% in fresh embryo transfer cycles and from 13,3% to 79,31% in FET cycles. Overall, LBR varied between 4,80% and 48,99% in fresh embryo cycles and between 6.06% and 39,19% in FET cycles. LIMITATIONS Only English-language studies were included; most studies were from the China region; retrospective study design used in most studies; different ET thresholds, which in turn could significantly alter the correlation with pregnancy outcomes; different IVF procedure protocols in fresh or FET cycles. CONCLUSIONS IVF outcomes in patients with impaired endometrial receptivity do not depend only on the condition of the endometrium. Risk factors and endometrial thickness significantly affect LBR in fresh and FET cycles.
