We performed this updated systematic review and meta-analysis to evaluate anti-Müllerian hormone levels (AMH) in newborns of mothers with polycystic ovary syndrome (PCOS) compared with healthy controls. A search of the literature was conducted in the PubMed, MEDLINE, EMBASE, Cochrane Library, CBM, CNKI, WANFANG, and VIP for articles to assess AMH levels in offspring of PCOS and non-PCOS mothers irrespective of language. These databases were searched from their inception to December 7, 2020. The quality of studies was assessed using the Newcastle-Ottawa Scale (NOS) scoring system. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were adopted to calculate the overall estimates with random-effects models. A total of 6 studies with 846 participants were included. The pooled analysis found an increased AMH level in the umbilical cord blood in newborns of PCOS mothers (SMD =0.62, 95% CI [0.28, 0.95]). Subgroup analyses revealed an elevation of AMH concentrations in female neonates, neonates born to American and Asian PCOS mothers. In addition, higher AMH levels were also found in studies diagnosed by the National Institute of Health (NIH) criteria, maternal clinical/biochemical hyperandrogenism, or maternal body mass index (BMI) >30 kg/m2. Meta-regression analysis suggested that diagnostic criterion contributed mostly to the high heterogeneity. We demonstrated that AMH levels in neonates born to PCOS mothers were essentially higher, which indicates that AMH may act as an enigmatic role in the pathogenesis of PCOS which inhibits folliculogenesis in the fetal stage.

Background Endometriosis is a progressive disease, and early detection and early treatment are particularly important. The purpose of this study was to investigate the effect of the timing of laparoscopy on the spontaneous pregnancy rate of primary infertile patients complicated with pelvic effusion within 6 months after surgery. Material/Methods We enrolled 330 primary infertile patients with pelvic effusion and bilateral patent fallopian tubes. They were divided into 3 groups based on retrospective analysis of clinical data. Study Group 1 underwent laparoscopy 1 month after hysterosalpingography (HSG), Study Group 2 received laparoscopy after trying to conceive for 3 months, and the Control Group did not undergo laparoscopy. According to the specific conditions during laparoscopy, repair and plastic surgery of fallopian tube, electrocautery of endometriosis and uterine suspension were performed. The main observation indicators were proportions of retrograde menstruation, peritoneal endometriosis, and tubal adhesions in laparoscopy groups, and spontaneous pregnancy rates within 6 months. Results The proportions of retrograde menstruation were 92.2% and 93.1% in Study Group 1 and Study Group 2, respectively, with no statistical significance. The proportions of peritoneal endometriosis were 51.0% and 64.7%, with a statistically significant difference. The proportions of tubal adhesions were 31.4% and 36.2%, with no statistical significance. The pregnancy rates within 6 months were 73.9%, 52.6%, and 13.1%, with a statistically significant difference for pairwise comparisons. Conclusions The pregnancy rate of primary infertile patients with patent fallopian tubes complicated with pelvic effusion can be significantly improved through early laparoscopic surgery (exploration and treatment).
