Women with hyperandrogenic disorders represent a unique group among those with infertility due to anovulation. Although antiestrogens are effective in restoring ovulation in most women, it remains unclear whether these treatments restore fecundability per ovulatory cycle and the ability to maintain pregnancy in these individuals. Moreover, antiestrogens are ineffective in restoring ovulation in some hyperandrogenic anovulatory women, whose condition poses unique and vexing challenges for the infertility therapist. Gonadotropin treatment in antiestrogen-resistant women often leads to ovarian hyperstimulation syndrome, which has been addressed by modification of dosing schedules (e.g., low-dose administration), pretreatment with gonadotropin-releasing hormone (GnRH) analogs, and elimination of luteinizing hormone from the administered gonadotropins. Surgical reduction in ovarian volume has met with some success, although there may be a risk of inducing surgical adhesions of the adnexa. The second major reproductive adversity facing these patients is their elevated risk of endometrial cancer. Unopposed estrogen exposure probably contributes to this risk, but hyperandrogenicity and hyperinsulinism may act independently or in concert with estrogen to amplify the risk in these women. While the risks and strategies for preventive care in these women need to be better defined, reproductive health specialists are urged to continue using presently accepted measures, including education, to maintain these women's reproductive health.

To assess the endocrinologic and clinical outcome after laparoscopic ovarian electrocautery because of polycystic reaction to ovarian stimulation in anovulatory infertility patients. Between 1986 and 1989, 133 patients with polycystic ovarian disease underwent laparoscopic electrocoagulation of the ovarian surface in an outpatient clinic after conventional ovarian stimulation had led to polycystic reaction. All patients were referred to our outpatient clinic affiliated with the university hospital. The reduction of androgen levels and normalization of cycle length were highly significant. The overall pregnancy rate was 70% (73 of 104), ranging from 27% in smokers to 94% in nonsmoking couples. In 26 second-look operations de novo adhesions were found in 26.9% of the patients. Laparoscopic coagulation of the ovarian surface is an effective tool to reduce elevated androgen levels and to improve the intraovarian mechanism of selecting a dominant follicle. A postoperative complication may be adhesion formation.
The present study investigated the role of melatonin (MT) in regulating mitochondrial function via sirtuin 3 (SIRT3) in granulosa cells (GCs) from patients with polycystic ovary syndrome (PCOS), with a focus on mitochondrial protection. Notably, GCs isolated from patients with PCOS exhibited mitochondrial dysfunction. Using an in vitro PCOS model established by treating KGN cells with dihydrotestosterone (DHT), decreased SIRT3 expression, dysregulated mitochondrial dynamics and hyperactivation of mitophagy were observed. Both SIRT3 overexpression and MT treatment restored the mitochondrial membrane potential, rebalanced mitochondrial dynamics and suppressed excessive autophagy in DHT-treated cells. Additionally, MT levels were shown to be reduced in the follicular fluid of patients with PCOS. Notably, the protective effects of MT on proteins associated with both mitochondrial dynamics and autophagy were abolished upon SIRT3 inhibition. In conclusion, mitochondrial dysfunction and aberrant mitophagy in GCs may serve a role in the pathogenesis of PCOS. MT appears to ameliorate these defects by modulating mitochondrial dynamics and function in a SIRT3-dependent manner. Moreover, the current study identified SIRT3 as a key molecular target of MT in PCOS.
Background Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine-metabolic disorder characterized by reproductive, hormonal, and metabolic disturbances. This study aimed to evaluate the association between clinical features, anthropometric indices, hormonal parameters, metabolic profile, ultrasonographic findings, and the second-to-fourth digit (2D:4D) ratio in women with PCOS compared to age-matched healthy controls. Methods A case-control study was conducted, including women diagnosed with PCOS and age-matched healthy controls. Clinical features, anthropometric measurements (BMI, waist-hip ratio (WHR), waist-height ratio (WHtR)), hormonal parameters (luteinizing hormone (LH), follicle-stimulating hormone (FSH), anti-Müllerian hormone (AMH)), metabolic variables (fasting glucose, lipid profile), ultrasonographic findings, and 2D:4D digit ratio were assessed. Statistical analysis was performed using appropriate tests, and a p-value < 0.05 was considered statistically significant. Results Women with PCOS exhibited a significantly higher prevalence of menstrual irregularity, polycystic ovarian morphology, hirsutism, and acne (p < 0.001). Hormonal analysis showed significantly elevated LH, FSH, and AMH levels in PCOS cases (p < 0.001). Anthropometric indices, including BMI, WHR, and WHtR, were significantly higher among PCOS cases (p < 0.01), indicating increased general and central adiposity. In contrast, fasting glucose and lipid profile levels did not differ significantly between groups. Additionally, the 2D:4D ratio was significantly lower in PCOS cases (p < 0.01) and showed significant negative correlations with BMI, WHR, WHtR, and cholesterol levels. Conclusion The study demonstrates that PCOS is associated with significant hormonal dysregulation, central obesity, and early metabolic alterations. The lower 2D:4D ratio observed in PCOS supports the role of prenatal androgen exposure in disease pathogenesis. These findings highlight the complex interplay between developmental, metabolic, and endocrine factors in PCOS and underscore the importance of early identification and comprehensive management strategies.

Polycystic ovary syndrome (PCOS) is an endocrine disorder that affects reproductive-aged women worldwide, causing hormonal imbalances and ovarian dysfunction. PCOS affects metabolic health and increases the risk of obesity, insulin resistance, and cardiovascular disease, in addition to infertility. This review delves deeper into the connections of gut microbiota with PCOS pathophysiology, particularly into its impact on hormone metabolism, obesity, inflammation, and insulin resistance by way of short-chain fatty acids, lipopolysaccharides, and gut-brain axis. Studies also show that changes in the metabolic processes and immune responses are seen in changes in the gut microbiota in PCOS subjects, such as changes in the Bacteroidetes and Firmicutes groups. Some bacteria, like Escherichia and Shigella, have been associated with dysbiosis in patients with PCOS, leading to systemic inflammation and changed hormone levels, which further worsen the clinical symptoms. Therapeutic interventions targeting the gut microbiota comprise probiotics, prebiotics, and fecal microbiota transplantation; these have potential to alleviate the symptoms of PCOS. Other precision microbiome-based therapies include postbiotics, and CRISPR-Cas9 genome editing, which are relatively new avenues toward precision treatment. This complex interlink of gut microbiota and PCOS pathophysiology will open the avenues for possible treatments for hormonal imbalances and metabolic problems that characterize these complex disorders. The review here focuses on the requirement of further studies to be able to elucidate the specific pathways relating gut microbiota dysregulation to PCOS and, thus, improve microbiome-based therapies for better clinical outcomes in affected individuals.
