Polycystic ovary syndrome (PCOS) is a common endocrinopathy characterized by increased ovarian androgen biosynthesis, anovulation, and infertility. PCOS has a strong heritable component based on familial clustering and twin studies. Genome-wide association studies (GWAS) identified several PCOS candidate loci including LHCGR, FSHR, ZNF217, YAP1, INSR, RAB5B, and C9orf3. We review the functional roles of strong PCOS candidate loci focusing on FSHR, LHCGR, INSR, and DENND1A. We propose that these candidates comprise a hierarchical signaling network by which DENND1A, LHCGR, INSR, RAB5B, adapter proteins, and associated downstream signaling cascades converge to regulate theca cell androgen biosynthesis. Future elucidation of the functional gene networks predicted by the PCOS GWAS will result in new diagnostic and therapeutic approaches for women with PCOS.

Background: Female reproductive disorders (FRDs) are common diseases among women of childbearing age, affecting their reproductive health. Age at first sexual intercourse (AFS) is potentially linked to FRDs, and this study aims to investigate these associations and underlying mechanisms, to offer new insights and guidance for sex education in adolescent women and reproductive health management.
Methods: Mendelian randomization (MR) analysis was performed using summary data from genome-wide association studies (GWASs).

Polycystic ovary syndrome (PCOS) is a common and heterogeneous disorder currently diagnosed only in reproductive-age women. Familial clustering and twin studies have provided strong evidence for a genetic contribution to PCOS pathogenesis. First-degree relatives, including males and non-reproductive-age females, have reproductive and metabolic phenotypes consistent with a genetic susceptibility to these traits.

Polycystic ovary syndrome (PCOS) is a multifactorial endocrine and metabolic disorder in women of reproductive age characterized by hormonal imbalances, menstrual irregularities, and changes in ovarian morphology. Excess body fat plays a significant role in the clinical development of PCOS. The complex relationship between adiposity and PCOS involves disruptions in hormonal balance and inflammatory processes, which both contribute to the clinical and phenotypic manifestations of the syndrome.

Polycystic ovary syndrome (PCOS) is among the most common disorders affecting up to 15% of the menstruating population globally. It is the leading cause of anovulatory infertility and a major risk factor for type 2 diabetes. Elevated testosterone levels are a core endophenotype.

Background: Evidence concerning the causal effects of blood metabolites on polycystic ovary syndrome (PCOS) risk remains scarce. A two-sample Mendelian randomization (MR) analysis was performed among individuals of European ancestry to establish a causal relationship between plasma metabolites and the risk of PCOS.
Objective: To determine causal associations between 1400 blood metabolites and PCOS.
