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.

Beta-glucans (βTGs) are a class of dietary fibers and biologically active polysaccharides derived from natural sources, known for their diverse bioactive properties. Their documented effects include anti-tumor, anti-inflammatory, prebiotic, anti-obesity, anti-allergic, anti-microbial, antiviral, anti-osteoporotic, and immunomodulating activities. Despite these well-established benefits, the role of βTG in dehydroepiandrosterone (DHEA)-induced polycystic ovary syndrome (PCOS) remains largely...

INTRODUCTION: Hyperandrogenism is a clinical condition in girls, resulting from excessive androgen production originating from the adrenal glands or ovaries. The measurement of androgen hormones plays an essential role in supporting the clinical diagnosis. These hormone levels can be assessed using immunoassay methods or liquid chromatography - tandem mass spectrometry (LC-MS/MS). Our study aimed to assess the efficacy of hormone measurement with both methods in girls clinically diagnosed with...

CONCLUSIONS: We observed regional reduction in cerebral blood flow and regional increase in cerebrovascular reactivity in women with PCOS compared to healthy controls. However, due to the limited statistical power and unclear menstrual timing in this pilot study, these results require further replication.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder, often characterized by polycystic ovarian, hyperandrogenism, and menstrual irregularities, which can lead to infertility and other metabolic issues. The mechanisms underlying these symptoms remain complex, with granulosa cells proliferation and apoptosis playing a key role in the pathogenesis of PCOS. In this study, we investigate the potential of metformin to regulate the miR-103a-3p/PTEN signaling pathway in granulosa cells,...

Pelvic pain is a common and often debilitating experience with limited treatment options. Improving understanding of the psychosocial mechanisms involved in pelvic pain experiences will enhance the efficacy of pain management interventions. Interpretation bias is a promising psychosocial factor in leading models of chronic pain, yet its relevance for pelvic pain remains poorly understood. The current study sought to assess disorder specific interpretation bias in people with endometriosis and...

Polycystic ovary syndrome (PCOS) is a prevalent chronic disorder characterized by reproductive, endocrine, and metabolic abnormalities in women worldwide. Increasing evidence has implicated the gut microbiota in the pathogenesis of PCOS, raising the possibility that probiotic interventions could offer therapeutic benefits. Akkermansia muciniphila (AKK), known for its metabolic and immunomodulatory properties, remains underexplored in the context of PCOS. In this study, we utilized a...

Epilepsy, a chronic neurological condition affecting over 70 million individuals worldwide, has far-reaching effects beyond seizure activity, including a significant impact on reproductive health by posing significant challenges to fertility and hormonal health. Emerging evidence underscores the complex bidirectional interplay between epilepsy, antiepileptic drugs (AEDs), and sex steroid hormones; particularly progesterone, testosterone, and prolactin, which influence both seizure threshold and...

CONCLUSIONS: Elevated DKK1 levels are strongly associated with PCOS and IR, suggesting a potential role in their development. This insight paves the way for further investigations into the role of DKK1 in PCOS and IR.

Polycystic ovary syndrome (PCOS), a common female endocrine disorder marked by disrupted folliculogenesis and hyperandrogenism, is increasingly linked to oxidative stress. Despite this association, the mechanistic basis remains poorly characterized. C-Phycocyanin (C-PC), a cyanobacteria-derived protein with potent antioxidant properties, has demonstrated therapeutic potential for treating PCOS, though the molecular pathways mediating its effects have yet to be delineated. This study employed...

CONCLUSION: High androgen induced pyroptosis of ovarian granulosa cells in a mouse model of PCOS, leading to ER stress in oocytes and a decrease of the oocyte maturation rate. Effective alleviation of granulosa cell pyroptosis can inhibit ER stress in oocytes and improve their maturation rate. This study provides new therapeutic targets for improving oocyte maturation in PCOS.

Polycystic ovary syndrome (PCOS) is a multifactorial disorder driven by at least three pathophysiological components: hypothalamic, ovarian, and obesity-related mechanisms. Insulin resistance (IR) is a unifying feature. Reciprocal interactions among androgen excess, hyperinsulinemia, and reduced hepatic sex hormone-binding globulin production create a self‑sustaining "vicious cycle" that exacerbates PCOS manifestations, which vary in severity and define four clinical phenotypes. To evaluate...

PURPOSE OF REVIEW: Sex steroid hormones and the gut microbiome are increasingly recognized as bidirectionally interacting regulators of growth, metabolism, and endocrine maturation. While most research has focused on adults, accumulating evidence indicates that these interactions are established early in life and influence pubertal timing, metabolic homeostasis, and neuroendocrine development. This review synthesizes current human evidence on microbiome-sex steroid relationships across childhood...
