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?

CONCLUSION: The global burden of non-neoplastic gynecological diseases among WCBA remains substantial, with marked heterogeneity across regions and conditions. These findings underscore the importance of strengthened disease surveillance, improved and equitable access to reproductive health services, and greater integration of mental health support in women's health strategies.

CONCLUSION: In overweight and obese women with PCOS, the addition of dapagliflozin to metformin did not result in significant improvement in insulin resistance or hyperandrogenaemia over metformin alone and was associated with a higher rate of adverse effects. Larger and longer-term trials are needed to fully clarify their role in routine clinical care.

Gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), mediate critical reproductive functions via the hypothalamus-pituitary-gonadal axis. Their levels fluctuate across the lifespan, particularly during puberty and menopause, and across the menstrual cycle. In addition to peripheral expression, gonadotropin receptors are widely expressed in the brain, notably in memory-associated regions such as the hippocampus and cortex. Alterations in FSH and LH during reproductive...

CONCLUSION: This study demonstrated that NCAH should be excluded when PCOS is accompanied by a significant increase in serum testosterone, that mass spectrometry of steroid hormone profiles containing 17-hydroxyprogesterone is useful for the detection of NCAH, and that TGS is advantageous in confirming the diagnosis of NCAH when compared with conventional genetic testing methods.

Metabolic syndrome (MetS) is a multifactorial cluster of cardiometabolic abnormalities, including central obesity, insulin resistance, dyslipidaemia, and hypertension, that significantly elevate the risk for type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), and non-alcoholic fatty liver disease (NAFLD). Although traditionally associated with adults, MetS is increasingly prevalent in the adolescent population, paralleling the global surge in childhood obesity. Early onset of MetS...

The protease activity of ADAMTS1 is essential for ovarian development and function. It cleaves and remodels the extracellular matrix (ECM) to accommodate growing follicles and the vascular networks. While the loss of ADAMTS1 activity affects ovulation and leads to pathological conditions like polycystic ovary syndrome (PCOS), an increased activity may result in premature ovarian failure and ovarian cancers. These findings highlight the precise action of this enzyme in maintaining normal ovarian...

Polycystic Ovarian Syndrome (PCOS) is a complex endocrine disorder whose pathophysiology extends beyond classical mechanisms of insulin resistance and hyperandrogenism. This review critically synthesizes recent advances from the past seven years that challenge conventional views and highlight emerging concepts. Key controversies such as the differing metabolic and reproductive phenotypes of lean versus obese PCOS, the causal versus associative role of gut microbiota dysbiosis, and the...

Inositol plays a crucial role in follicular development by regulating insulin signaling and ovarian function. However, its precise mechanism of action remains unclear. This study investigated the effects of myo-inositol (MI) and D-chiro-inositol (DCI) on the development of murine ovarian follicles in vitro. Follicles treated with DCI exhibited larger diameters than controls on Day 6 (275.20 ± 12.54 μm; p = 0.037) and Day 8 (277.47 ± 11.47 μm; p = 0.048), indicating a modest, marginally...

CONCLUSION: Serum kisspeptin levels are elevated in women with PCOS, particularly among those with overweight/obese BMI, suggesting a possible interaction between metabolic status and reproductive neuroendocrine regulation. These findings support the potential of kisspeptin as a biomarker for PCOS and highlight the need for further research into its mechanistic role and clinical applicability.

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder in women. Accumulating evidence indicates that gut dysbiosis and metabolic disturbances are associated with the pathogenesis of PCOS. However, the mechanisms by which metabolic alterations influence gut homeostasis and contribute to PCOS progression remain poorly understood. Here, we show that N-acetylneuraminic acid (Neu5Ac) exacerbates dehydroepiandrosterone (DHEA)-induced PCOS phenotypes in female mice in a gut...

This review presents a novel conceptual framework-the Multi-Hit, Multi-Level Cascade Model-that systematically integrates evidence from systems toxicology, molecular endocrinology, and epidemiology. Our model posits that chronic exposure to real-world EDC mixtures initiates a cascade of events wherein cellular perturbations (oxidative stress and low-grade inflammation) are amplified within the uniquely vulnerable ovarian microenvironment. This cascade then escalates into a systemic,...

Polycystic ovary syndrome (PCOS) is an endocrine and metabolic condition affecting reproductive health, marked by disrupted ovulation, excessive androgen levels, and impaired endometrial receptivity. Oxidative stress is an important part of its pathophysiological process. Atractylenolide III (ATIII), a major sesquiterpene lactone derived from Atractylodes macrocephala Koidz., exhibits antioxidant properties; however, its role and molecular mechanisms in PCOS have not yet been explored. A PCOS...

CONCLUSIONS: QGW is capable of enhancing the expression of genes related to endometrial receptivity in PCOS model rats and increasing the number of pinopodes, thereby improving the endometrial receptivity in PCOS rats. The results suggest that QGW may improve endometrial receptivity potentially through upregulation of Hoxa11 accompanied by increased Itgβ3 and decreased Igfbp1. However, whether Hoxa11 directly binds to the promoter regions of relevant genes requires further validation. Network...

CONCLUSION: In our study, body appreciation emerged as a promising psychological mechanism linking undiagnosed PCOS to binge eating and night eating. These findings suggest that body appreciation is a promising psychological goal to improve adaptive eating and reduce disordered eating features in women with undiagnosed PCOS.
