Despite what the name suggests, Polycystic Ovary Syndrome isn’t just about ovaries—or cysts, for that matter. In fact, many people diagnosed with PCOS don’t have any ovarian cysts at all. Confusing? You’re not alone. The name dates back to how the condition was first described, but science has come a long way since then. Today, we understand that PCOS is really a complex hormonal and metabolic condition that affects far more than reproductive health.
At its core, PCOS is about hormonal imbalance. When key hormones like insulin, androgens (like testosterone), and others are out of sync, they can create a domino effect throughout the body. This hormonal miscommunication can lead to irregular periods, acne, weight changes, hair loss or excess hair growth, difficulty with ovulation or fertility—and that’s just the shortlist. But here’s the thing: PCOS doesn’t follow a single pattern. Some women experience textbook symptoms. Others don’t fit the mold at all. That’s part of what makes PCOS so challenging—and why understanding your unique experience matters.
So, how can the PCOS Association help?

Polycystic ovary syndrome (PCOS) can lead to increased abortion rates. Quercetin treats PCOS, but its specific mechanism has not been fully clarified. PCOS was induced in mice by dehydroepiandrosterone, and decidualization was induced by corn oil. Mice were treated with quercetin, autophagy inhibitor 3-MA, autophagy inducer rapamycin, PI3K inhibitor LY294002, and PI3K inducer 740Y-P. Pathological damage in the ovary and uterus was observed by HE staining. The levels of sex hormones, metabolism,...

CONCLUSIONS: OVRAS shows hormone-regulated expression during normal folliculogenesis and is disrupted in the DHT-induced PCOS mouse model, paralleling human pathology. Its upregulation in interstitial cells following androgen exposure is associated with theca cell hyperplasia and excess androgen production, suggesting a role in PCOS-related follicular dysfunction. These results position OVRAS as a potential molecular marker and therapeutic target in ovarian disorders. Further studies are needed...

Endometrial cancer (EC) is a major reproductive system tumor and a common cancer in women. Polycystic ovary syndrome (PCOS) is one of the most prevalent female reproductive endocrine disorders. The incidence of EC is significantly higher in individuals with PCOS. This study seeks to elucidate the organic correlations and interaction mechanisms between the 2 diseases through series of exploration of key genes with a bioinformatics analysis. The PCOS sample data and the EC single-cell dataset were...

Polycystic ovary syndrome (PCOS) is one of the causes of endocrine disorders and infertility in women of childbearing age, which seriously affects women's health. The etiology of PCOS is still unknown, and metabolic abnormalities are the focus of current research. A large number of studies have shown that gut microbiota is related to metabolic abnormalities. This project intends to study the relationship between gut microbiota and PCOS and analyze the molecular mechanism of its impact on PCOS....

Polycystic ovary syndrome (PCOS) is a gynecological endocrine disorder affecting 5%-18% of women of reproductive age worldwide. It is characterized by hyperandrogenemia (HA), anovulation, and polycystic ovarian morphology (PCOM), severely impacting women's reproductive and metabolic health. Obesity has become increasingly common among PCOS patients in recent years. Obesity can further exacerbate the metabolic and reproductive dysfunctions of PCOS through mechanisms such as insulin resistance...

CONCLUSIONS: WNT5A inhibits steroidogenesis via the PI3K/AKT pathway in granulosa cells. Our findings suggest that increased WNT5A may be attributed to inflammation and may result in endocrine dysregulation in PCOS patients.

CONCLUSION: Hyperandrogenism triggers granulosa cells ferroptosis in PCOS, while exercise and irisin protect ovarian function by regulating the NCOA4-FTH pathway, suggesting a potential therapeutic target for PCOS.

Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder among adolescent females and women of reproductive age. Ferroptosis is a newly recognized form of programmed cell death characterized by lipid peroxidation, which is iron-dependent and involves an elevation in cellular reactive oxygen species (ROS). In this study, we investigated the role of ferroptosis-related genes in PCOS through integrative bioinformatics and experimental validation. Differential expression analysis of...

Polycystic ovary syndrome (PCOS) is one of the most common endocrine diseases characterized by hyperandrogenemia and anovulation. The present study aimed to estimate heat shock protein 70 (HSP-70) in PCOS patients. This case-control study involved 90 females aged 15 to 45 years, divided into two groups: 45 controls and 45 PCOS patients. Levels of HSP-70, anti-Müllerian hormone (AMH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin, and testosterone were measured using...

11-beta hydroxylase deficiency (11βOHD) is a rare variant of congenital adrenal hyperplasia (CAH) with autosomal recessive inheritance, resulting in androgen excess and mineralocorticoid precursor accumulation. Fertility is often impaired due to hyperandrogenism and anatomical abnormalities, and spontaneous successful pregnancy in classic form is rare. We describe two cases. Case 1 is a 27-year-old woman with genetically confirmed classic 11βOHD (homozygous CYP11B1 splice-site variant...

CONCLUSION: Exercise remodels the gut microbiota-metabolism-immune network to reverse PCOS pathophysiology. Targeting microbial metabolites (e.g., butyrate, BAs) or their receptors (FXR, GPR43) offers novel therapeutic strategies. Future research must address PCOS heterogeneity and optimize exercise protocols for microbiota-directed precision medicine.

It is well known that hyperandrogenism (HA) in females is associated with oligo-ovulation or anovulation, leading to subfertility. The abnormality in ovulation is due to ovarian dysfunction. However, it remains unclear whether ovarian dysfunction is the sole cause of subfertility. The crosstalk between sperm and the hyperandrogenized female reproductive tract has yet to be explored in the context of subfertility or infertility. Therefore, in the present paper, we hypothesized that firm sperm...
