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 metabolic disorder that affects 6% to 21% of women of reproductive age. It is characterized by hyperandrogenism, ano/oligo-ovulation, and ovarian cysts. Insulin resistance is a common finding among women with PCOS. To effectively manage PCOS, efforts must be focused on improving insulin resistance, as it has been noted to play a major role in a multitude of life-altering and life-threatening conditions. Intermittent fasting (IF) is a dietary intervention...

CONCLUSION: Smoking or SHS exposure was significantly associated with metabolic and hormonal profiles in women with PCOS. Despite observational limitations and absent e-cigarette data, the evidence supports advising PCOS patients to avoid smoking and SHS exposure.

Polycystic Ovary Syndrome (PCOS) presents unique diagnostic and management challenges in adolescents due to physiologic overlap with normal puberty. This review synthesizes current adolescent-specific guidelines to identify evidence-based diagnostic criteria for adolescent PCOS, to apply first- and second-line management strategies, and to recognize key areas of controversy and unmet need. We emphasize menstrual irregularities and hyperandrogenism as key diagnostic criteria, while noting the...

Polycystic ovary syndrome (PCOS) is a common gynaecological disorder, clinically characterized by chronic anovulation and hyperandrogenism. Despite its high prevalence, no curative treatment exists, and managing the syndrome remains challenging. A strong association between PCOS and metabolic syndrome, particularly insulin resistance, adversely influences fertility, leading to an increased worldwide demand for advanced treatment options. Although the exact aetiology and pathophysiology of the...

CONCLUSION: The identified common pathways signify the overlap between PCOS, RA, and OA. These findings support the hypothesis of systemic immunometabolic involvement in PCOS.

CONCLUSIONS: In this long-term, population-based cohort of Iranian women, the PREVENT risk model showed good discrimination and acceptable calibration for predicting 10-year CVD risk in both the general population and women with PCOS/Isolated-PCOS phenotypes. Performance was highest in women under 55 years, with some underestimation of risk in older or high-risk individuals.

Although increased maternal androgens, such as those in polycystic ovary syndrome (PCOS), are associated with a higher incidence of autism spectrum disorder (ASD) in offspring, a causal link has yet to be established. We assessed whether perinatal hyperandrogenization in a murine model recapitulates core ASD traits and compared this model to the maternal immune activation (MIA) model of ASD. Both models produced ASD-like phenotypes, yet they exhibited distinct behavioral subtypes and...

CONCLUSION: Galangin provides multidimensional protection against letrozole-induced ovarian dysfunction by alleviating oxidative stress, inflammation, and dysregulation of the PI3K/pAKT/PTEN pathway. These findings support the potential of galangin as a safe, multitarget natural adjunct for managing PCOS.

Endocrine-disrupting chemicals (EDCs), including bisphenol A (BPA), phthalates, organochlorine pesticides, and heavy metal ions, pose serious threats to reproductive health by interfering with hormonal balance and molecular signaling pathways. Recent research had expanded our understanding of these compounds has beyond their traditional role in hormone receptor interference. EDCs can trigger lasting epigenetic changes, including abnormal DNA methylation, histone modifications, RNA methylation,...

CONCLUSION: Mitochondrial dysfunction and inflammation are interdependent mechanisms that contribute substantially to cardiovascular risk in women with PCOS. Targeting mitochondrial dysfunction and systemic inflammation presents a promising therapeutic strategy for reducing cardiovascular morbidity in PCOS. Future research should emphasize phenotype-specific interventions, biomarker discovery, and translational trials to improve long-term reproductive and cardiovascular outcomes.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder, with a reported worldwide prevalence of 5%-20% in women of reproductive age. It is defined primarily by hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology. In addition to the reproductive and metabolic features of PCOS, patients often experience chronic pain, which is the most frequently reported symptom. Pain in the pelvic area, dysmenorrhea, bloating, and abdominal cramping are all common in PCOS patients....

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a complicated endocrine condition marked by reproductive, metabolic and chronobiological perturbations. Despite a number of biomarkers that can be used in its diagnosis, they only show the existence of the syndrome and not much information about prognosis. This prognostic blindness complicates disease management and contributes to increased healthcare and economic burden.

CONCLUSION: . Greater baseline cardiometabolic risk was largely BMI-related in TGD with PCOS compared to TGD without PCOS. Only hyperlipidemia and elevated ALT were more prevalent during TT after adjusting for BMI. These findings support cardiometabolic monitoring during TT in all TGD individuals without significant increased risk with PCOS history.
