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?
We’re here to offer more than definitions. We’re here to offer direction. Whether you’re newly diagnosed, still searching for answers, or years into your journey and feeling stuck, we’re committed to helping you make sense of PCOS—and make progress.

Polycystic Ovary Syndrome (PCOS) is a common reproductive and metabolic disorder causing infertility in women of childbearing age.Circular RNAs are known to be involved in PCOS development, but their regulatory mechanisms remain unclear. This study explored the role of circ_BMPR2 in PCOS to advance early diagnosis and treatment.It found elevated circ_BMPR2 expression in ovarian granulosa cells of PCOS patients. Knocking down of circ_BMPR2 inhibited proliferation and promoted apoptosis in KGN...

Polycystic ovary syndrome (PCOS) lacks the generally accepted diagnostic biomarkers and targeted therapy. Increasing evidence indicates that microRNAs (miRNAs) play a crucial role in PCOS. Hereby, we tested the functional implications of a novel miRNA (miR-423-3p) as a mediator in the progress of hyperandrogenic PCOS, as well as its potential as a new serum biomarker and therapeutic target for the PCOS. We found significantly decreased miR-423-3p levels in serum, granulosa cells (hGCs), and...

CONCLUSION: Our research indicates that age specific AMH threshold values show promising sensitivity and specificity for PCOS screening in the validation cohort. These findings indicate the potential utility of AMH based screening, but emphasize the need for optimization and validation in larger multicenter studies before clinical implementation.

CONCLUSION: BHHF exerts multi-targeted therapeutic effects on obesity-associated PCOS by regulating metabolic-reproductive crosstalk. Its components act synergistically, offering a novel therapeutic strategy for PCOS treatment. Future research should focus on identifying core active compounds and optimizing treatment according to individual PCOS phenotypes.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder with dysfunctional ovulation affecting female fertility. The purpose of this study was to determine the association between gonadotropin (Gn) duration and in vitro fertilization (IVF) outcomes in PCOS women undergoing GnRH antagonist treatment. Retrospective cohort study at a large private fertility practice. Patients with PCOS undergoing the GnRHantagonist treatment between January 1, 2017, and July 31, 2021 were included. Patients...

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder often worsened by obesity, leading to chronic inflammation, metabolic dysregulation, and reproductive dysfunction. This study aims to uncover the molecular mechanisms underlying reproductive dysfunction in obese PCOS patients by identifying key regulatory genes, pathways, and immune interactions, with a focus on cross-tissue regulators and potential therapeutic targets. We analyzed transcriptomic data from multiple datasets,...

CONCLUSIONS: This research highlights potential environment-related biomarkers for PCOS, emphasizing the importance of developing tailored treatment strategies considering environmental factors. The distinct metabolic profiles observed between urban and rural women provide new insights into the syndrome's complex mechanisms, indicating that environmental influences play a critical role in its biochemical expression and may affect its clinical manifestations.

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder with diverse metabolic and hormonal manifestations. Insulin-like peptide 5 (INSL5), a gut-derived hormone of the relaxin/insulin family, is expressed in the central nervous system, colonic and reproductive tissues, but its clinical significance in PCOS remains unclear. This study aimed to evaluate circulating INSL5 levels in PCOS and explore their associations with key hormonal and metabolic parameters. In this prospective...

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder characterized by cystic ovarian morphology, anovulation, and infertility. Ovarian fibrosis has recently emerged as a key pathological feature of PCOS. This study investigated whether pirfenidone (PFD), an antifibrotic agent, could improve ovarian dysfunction in a letrozole-induced PCOS rat model. Forty-two female Wistar albino rats were divided into six groups (n=7 each): control, PFD, PCOS, PCOS/PFD, PCOS/combined oral...
