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.

Accurate and timely diagnosis remains a challenge due to the complexity of Polycystic Ovary Syndrome (PCOS) symptoms and data imbalance issues in the existing datasets. This research aims to develop a robust PCOS detection model that addresses these challenges by introducing a novel hybrid methodology with effective feature prioritization while handling data balancing issues. The research involves three major phases: pre-processing, feature selection, and PCOS detection. In the pre-processing...

Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder in women of reproductive age, markedly impairing their health and reducing overall quality of life. Vitexin is a natural flavonoid compound that has demonstrated diverse pharmacological properties, including anti-inflammatory and antioxidant effects. The aim of this study was to investigate the effects of vitexin on dihydrotestosterone (DHT)-induced fibrosis in KGN cells, as well as its regulatory role in the...

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a multifactorial endocrine disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology, frequently accompanied by insulin resistance, inflammation, and other metabolic disturbances. Chromogranin A (CgA), a glycoprotein secreted by neuroendocrine cells, has been linked to metabolic regulation and inflammatory processes, but its role in PCOS remains unexplored. This study aimed to evaluate serum CgA levels...

Polycystic ovary syndrome (PCOS) ranks among the most widespread endocrine and metabolic conditions affecting women of childbearing age, but its specific pathogenesis remains unknown. More and more evidence indicates that PCOS may be a complex polymorphic disease, influenced by epigenetic and environmental factors, including diet and lifestyle. This review focuses on the role of the gut microbiota and its metabolites in PCOS, a topic that has gained significant attention recently due to the...

CONCLUSION: This study, for the first time, systematically investigated the potential association between PCOS and EC through an integrative approach combining bioinformatics analysis and MR analysis. Type I interferon signaling pathway played key regulatory effect in PCOS and EC. Eight genes, such as MMP9, PECAM1 and CYBB, may be key markers linking PCOS and EC.

Polycystic ovary syndrome (PCOS) is the most common endocrine-metabolic disorder in reproductive-age women, characterized by hyperandrogenism (HA) and insulin resistance (IR). Despite its high prevalence, the underlying pathophysiology remains incompletely understood. In recent years, bidirectional interactions between androgens and adipose tissue (AT) have been recognized as a key driver of the vicious cycle in PCOS. This review systematically examines this core interaction mechanism: on one...

This review takes a close look at the biology of brown and beige fat, not just as thermogenic tissues, but as active metabolic organs influenced by sex, hormones, age, and even environment. Brown adipose tissue (BAT) and beige adipocytes differ in their origins, gene expression, and regulation. These differences are especially relevant when considering how they behave in males and females. Across both animal and human studies, females show higher BAT volume and more efficient thermogenic...

Polycystic ovary syndrome (PCOS) is a common hormonal disorder of reproductive-aged women all over the world. Low- and middle-income countries, such as Bangladesh, often give inadequate attention to mental health issues. As a result, a growing number of women with PCOS are dealing with mental health issues, including an under diagnosis and under-treatment of psychological illnesses. The study assesses the prevalence and psychological impacts of PCOS among women in the reproductive age as well as...

Acne vulgaris is one of the most prevalent dermatologic disorders in adolescent and adult women. Beyond classic pathogenic factors, such as sebaceous hypersecretion, follicular hyperkeratinization, Cutibacterium acnes overgrowth, and inflammation, endocrine drivers are pivotal. Polycystic ovary syndrome (PCOS) is common across reproductive ages and frequently presents with dermatologic manifestations, notably acne, through mechanisms dominated by hyperandrogenism and compounded by insulin...
