What is PCOS?

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.

Wearable molecularly imprinted polymer sweat testosterone sensor for noninvasive auxiliary early-stage polycystic ovary syndrome at rest

Androgens, comparable in importance to estrogens, are essential for female reproductive and physiological health. Polycystic ovary syndrome (PCOS), often caused by elevated testosterone (the primary androgen in females) is characterized by reproductive dysfunction, infertility, and metabolic abnormalities. However, current testosterone assays remain invasive, technically complex, and insufficiently sensitive, limiting their utility for early and noninvasive PCOS screening. This study developed a...

The role of psychological care in the treatment of gynecological disorders in girls and young women - an interdisciplinary perspective

This review article explores the psychological dimension of gynecological disorders in girls and young women, emphasizing the need for interdisciplinary approaches in medical care. Gynecological conditions such as endometriosis, polycystic ovary syndrome (PCOS), and disorders of sex development (DSD) often co-occur with psychological challenges including depression, anxiety, body image issues, and identity-related stress. The chronic nature of symptoms, delayed diagnosis, and potential...

Chronic inflammatory activity in women with normogonadotropic anovulation complicated by subclinical thyroid dysfunction: a prospective cohort study

CONCLUSIONS: SCH and TAI independently and synergistically promoted chronic inflammation in normogonadotropic anovulation, particularly in PCOS, through elevated TNF-α and disrupted interleukin-1β/IL-10 balance, with significant implications for metabolic health and ovarian function.

Ocimum tenuiflorum L. extracts attenuate polycystic ovarian syndrome in letrozole treated female Wistar rats through modulation of iNOS, COX-2, IL-1β and TNF-α

Polycystic ovary syndrome (PCOS) is a prevalent endocrine abnormality affecting the women of child bearing age. PCOS markedly raises the chances of infertility, cardiovascular disease, and increased blood pressure. Ocimum tenuiflorum is known for its diverse roles and is used in Ayurveda to address a variety of pathological conditions. This study was done to scrutinize the role of inflammatory genes such as iNOS, COX-2, IL-1β, and TNF-α in letrozole-induced PCOS in female Wistar rats and to...

Effects of GLP-1 Receptor Agonists vs Metformin in Polycystic Ovary Syndrome: A Systematic Review and Meta-Analysis

Polycystic ovarian syndrome (PCOS) is a common endocrine disorder associated with significant metabolic and reproductive dysfunction. Although metformin has long been a cornerstone of PCOS management, glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) have emerged as promising alternatives, particularly for improving metabolic outcomes. This systematic review and meta-analysis aimed to evaluate the effects of GLP-1 RAs compared with metformin on metabolic, hormonal, and reproductive...

Analysis of Laparoscopic and Transvaginal Ovarian Drilling on Polycystic Ovarian Syndrome: A Narrative Review of Outcomes

The primary objective of polycystic ovarian syndrome (PCOS) treatment is to achieve mono-ovulatory cycles, thereby enabling pregnancy and childbirth. Laparoscopic ovarian drilling (LOD) and transvaginal ovarian drilling (TVOD) are widely used second-line treatments for ovulation induction in PCOS patients who do not respond to clomiphene citrate (CC). LOD involves the application of heat or laser energy to create small perforations in the ovary, whereas TVOD involves ultrasound-guided ovarian...

Network pharmacology analysis of integration of dietary plant-derived natural flavonoids and gut microbiota for the treatment of Polycystic Ovary syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder manifested by hyperandrogenism, ovulatory dysfunction, and systemic metabolic dysregulation. While the 'gut-diet' axis offers potential therapeutic avenues, the synergistic molecular mechanisms integrating dietary flavonoids and gut microbiota remain elusive. This study employed a comprehensive network pharmacology approach, coupled with molecular docking validation, to decode the tripartite interaction network of 'Dietary...

Dissociation Between Metabolic Improvements and Mitochondrial Transcriptional Changes Following Exercise Training in Women with Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder associated with insulin resistance and affecting women of reproductive age. Although the aetiology and the underlying molecular mechanisms of metabolic dysregulation in PCOS remain unclear, regular physical activity is known to ameliorate metabolic dysfunction. In this study, we investigated the transcriptional and epigenetic adaptations to exercise training in women with PCOS (n = 8). Following 12 weeks of high-intensity...

Diagnosis of Polycystic Ovary Syndrome With Predictive Modeling of Select Clinical Features

CONCLUSION: A minimum combination of ovarian volume with AMH and examination/history-derived end points can accurately predict PCOS diagnosis with performance comparable to that of a combination of all ultrasonographic, biochemical, and clinical features. This may streamline diagnostic workflows, thereby reducing clinical burden.
