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.

The frequency of polycystic ovary syndrome (PCOS) appears to be higher in women living with type 1 diabetes (T1D). Both diseases are characterized by a mild chronic inflammatory state. The proinflammatory protein profile in this population has not been fully evaluated. We conducted a cross-sectional, exploratory study in patients at the T1D Clinic from a tertiary referral hospital in Mexico. Using stored samples from a previous cohort, we categorized patients with T1D with or without PCOS,...

Polycystic ovary syndrome (PCOS), a common endocrine disorder affecting over 10% of women, is characterized by hyperandrogenism and ovarian dysfunction. While linked to chronic inflammation and granulosa cell apoptosis, its molecular mechanisms remain unclear. In this study, we elucidated the novel role of Krüppel-like factor 5 (KLF5) in the pathogenesis of PCOS and its regulatory role with thioredoxin interacting protein (TXNIP). In a mouse model of PCOS induced by dehydroepiandrosterone...

CONCLUSION: Current evidence suggests that acupuncture combined with letrozole may be more effective for PCOS than letrozole alone; however, the quality of this evidence is low, necessitating further high-quality research to confirm these findings.

CONCLUSION: Women with PCOS exhibit poorer health despite only slight lifestyle differences. Across all participants, lower physical activity and higher sedentary behaviour were linked to increased health risks. Further research is needed to clarify causal relationships between lifestyle factors and PCOS.

CONCLUSION: GnRH-a pretreatment at either 1.5 mg or 3.75 mg did not confer a clear benefit over HRT alone in PCOS patients undergoing FET. The number of embryos transferred remains the primary determinant of pregnancy outcome. Larger prospective studies are warranted to validate these findings.

CONCLUSIONS: After controlling for major confounders, a significant association between PCOS and vitamin D deficiency persists in this population. This adjusted analysis strengthens the finding that PCOS is an independent correlate of vitamin D status, beyond the effect of BMI. These results support the need for screening and inform future interventional studies.

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that significantly affects women's reproductive health and quality of life. Its pathogenesis involves multiple factors, including genetics, environment, and metabolism. In recent years, with the growing body of research on PCOS, the "gut-ovary axis" hypothesis has become a prominent research focus. This hypothesis suggests that an imbalance in gut bacteria may significantly influence the onset and progression of PCOS...

Polycystic Ovarian Syndrome (PCOS) is a complex endocrine and metabolic disorder affecting women of reproductive age, characterized by hyperandrogenism, insulin resistance, chronic inflammation, and ovulatory dysfunction. Conventional therapies, such as oral contraceptives, insulin sensitizers, and anti-androgens, primarily offer symptomatic relief and are often associated with chronic adverse effects, underscoring the need for safer and more holistic alternatives. Naturally occurring bioactives...

CONCLUSIONS: TPOAb positivity is not associated with adverse embryonic or pregnancy outcomes in euthyroid PCOS patients undergoing IVF/ICSI treatment. Therefore, the presence of TPOAb alone should not be overemphasized, nor does it warrant overtreatment in this patient population.

Polycystic ovarian syndrome (PCOS) is one of the leading causes of abnormalities in young female patients. Myricetin is flavonoid which has multiple pharmacological effects like anti-inflammatory, antidiabetic, and anticancer. This study determined the effect of myricetin in the treatment of PCOS. For in silico studies, network pharmacology and molecular docking and simulation were done through multiple software tools. In vitro evaluation was done through antioxidant assays (DPPH and ABTS)....

To investigate the causal relationship between follistatin (FST) levels and endocrine diseases such as polycystic ovary syndrome (PCOS), type 2 diabetes (T2DM), obesity, and osteoporosis (OP) using a 2-sample Mendelian randomization (MR) analysis. Instrumental variables closely associated with FST levels were obtained from large-scale genome-wide association study data in the IEU database. Summary-level data for 4 endocrine diseases were sourced from the latest version of the FinnGen database....

CONCLUSION: 11-oxygenated androgens at high concentrations directly inhibit brown adipocyte differentiation in vitro and KT acutely downregulates BAT metabolic transcriptome in vivo, a result not observed with KDHT. These findings suggest that elevated 11-oxygenated androgens may impair BAT function, contributing to metabolic complications associated with hyperandrogenic conditions, including PCOS.
