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.

Here’s what you’ll find at PCOSA:

Therapeutic potential of Corydalis alkaloids in polycystic ovary syndrome: In silico and preliminary In vitro Insights into ESR1 and SRC-associated pathways

CONCLUSION: C. bungeana Turcz. and C. decumbens (Thunb.) Pers. possess a range of bioactive compounds with potential therapeutic effects on PCOS. The network pharmacology approach unveiled the multi-faceted interactions of these compounds with PCOS-related biological pathways, providing a foundation for the development of novel, multi-targeted therapeutic strategies for PCOS. Further experimental and clinical validation is required to translate these findings into tangible clinical benefits.

Effect of orlistat and anti-androgen oral contraceptives on pregnancy outcomes in overweight or obese PCOS patients during comprehensive management

CONCLUSION: This study demonstrates that preconception combination therapy with DRSP/EE and orlistat significantly reduces the risk of GDM in overweight or obese women with PCOS. DRSP/EE monotherapy also exhibits a potential protective trend, although the effect is less robust compared to the combination regimen. While differences in HDP and other pregnancy outcomes did not reach statistical significance, the combination therapy group yielded the most favorable clinical profile, achieving the...

Neurotrophin and Adipokine Signatures Associated with Visceral Adiposity-Driven Cardiometabolic and Endocrine Risk in Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine-metabolic disorder associated with insulin resistance (IR), visceral adiposity, and increased cardiometabolic risk. The visceral adiposity index (VAI) is a validated surrogate marker of adipose tissue dysfunction, but its relationship with circulating neurotrophins and adipokine balance in PCOS remains incompletely understood. In this study, 100 women with PCOS were stratified into lower- (n = 50) and higher-risk (n = 50) groups...

The Plasma Glycome Differences Between Women with PCOS and Healthy Controls

While PCOS research has extensively explored genomic, transcriptomic, proteomic, and metabolomic milieus, our study examines the plasma glycome, comparing women with PCOS to age-matched healthy controls. In this observational study, n = 47 women with PCOS were screened and enrolled at the UC Davis Health campus; the comparator group constituted of n = 25 age-matched healthy women. During a study visit, body weight and body composition were measured, and fasted plasma samples were obtained to...

The Effect of Umbilical Cord-Derived Mesenchymal Stem Cells and Secretome on Metabolomic Profiles (C-Peptide, Adiponectin, Fasting Insulin, and Fasting Glucose): A Randomized Controlled Trial

Background: Polycystic ovary syndrome (PCOS) is a prevalent endocrine-metabolic disorder with chronic low-grade inflammation and insulin resistance (IR). Elevated C-peptide, a marker of compensatory hyperinsulinemia and reduced adiponectin, an insulin-sensitizing adipokine, contribute to the metabolic dysregulation observed in PCOS. Human umbilical cord-derived mesenchymal stem cells (UC-MSCs) and their secretome have immunomodulatory properties via paracrine and epigenetic mechanisms, yet...

One-Hour Plasma Glucose and Early Cardiometabolic Risk in Normoglycaemic Women With Polycystic Ovary Syndrome: A Retrospective Cross-Sectional Study

CONCLUSIONS: Among normoglycaemic women with PCOS, elevated 1hPG was associated with a less favourable cardiometabolic profile and a higher cross-sectional cardiometabolic risk burden. 1hPG may serve as an adjunct marker within routine OGTT interpretation for early cardiometabolic risk enrichment, but prospective validation is needed.

Comparison of Long-Term and Stimulated Cycle Protocols in Frozen Embryo Transfer Cycles in Women with Polycystic Ovary Syndrome: A Non-Randomized Clinical Trial

CONCLUSION: Although the long-term protocol showed higher clinical pregnancy rates in unadjusted analyses, after adjusting for confounders, protocol type was not independently associated with clinical pregnancy. Larger randomized trials are needed to confirm these findings, and adverse outcomes should be assessed in future studies.

Systems-level actions of luteolin in female reproductive disorders: from molecular mechanisms to clinical translation

Female reproductive disorders represent a major global health challenge. Despite their clinical heterogeneity, these conditions share core pathological mechanisms including oxidative stress, chronic inflammation, hormonal imbalance, metabolic dysfunction, extracellular matrix remodeling, and dysregulated cell survival. Current therapies rarely target these interconnected processes, underscoring the need for multi-pathway modulators. Luteolin, a dietary flavone, has emerged as a promising...
