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.

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.

CONCLUSION: Serum ferritin levels were not elevated in PCOS women undergoing infertility treatment and they only had a weak positive association with the developmental potential of embryos, suggesting serum ferritin has no significant association with embryological outcomes in women undergoing ART.

CONCLUSION: The study proposes use of circRNA Pum1_0014, miRNA-141-3p, and miRNA-146a as new biomarkers in PCOS, and indicates their probable roles in the hormonal and metabolic imbalances in PCOS.

Background/Objectives: Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder characterized by reproductive and metabolic dysfunction. Vitamin D deficiency is common in women with PCOS and is linked to adverse metabolic and reproductive outcomes. However, the role of vitamin D supplementation in managing PCOS remains unclear due to the heterogeneous evidence available. This systematic review aimed to synthesize both observational and interventional studies to assess the association...

Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder, primarily characterized by reproductive dysfunction, insulin resistance (IR), and long-term metabolic complications. Current first-line pharmacological treatments, including oral contraceptives, anti-androgens, and insulin sensitizers, can alleviate clinical symptoms but often fail to fully address the underlying pathophysiology, and their long-term use is frequently limited by adverse effects. Natural products,...

CONCLUSIONS: MI may have a synergistic effect at the cellular level, and the possible increase in the re-differentiation of RAIR-TC in patients treated with KIs plus MI may have great clinical relevance. The re-uptake of RAI will be evaluated as the primary endpoint, and Tg values and QoL will be evaluated as the secondary endpoints. The main limitation of this study is that we do not investigate any clinical effects. We will have to postpone the clinical analysis to a later date after the...

Background/Objectives: Although anti-Müllerian hormone (AMH) is a strong biomarker of ovarian reserve and oocyte pools, it is unknown whether high AMH levels can be a reliable predictor of oocyte quality, ovulation, and embryo quality. We aimed to determine whether there is any AMH threshold value that can be used to predict treatment success in women with clomiphene citrate (CC) resistance or failure in polycystic ovary syndrome (PCOS). Methods: This retrospective cohort study included 93...

Polycystic ovary syndrome (PCOS) is associated with impaired ovarian steroidogenesis and ovulation, which necessitates the development of effective ovulation inducers for PCOS. The aim of the study was to evaluate the effects of allosteric luteinizing hormone receptor agonist TP03 and human chorionic gonadotropin (hCG) on ovarian steroidogenesis, as well as ovulation in prepubertal female rats with dehydroepiandrosterone(DHEA)-induced PCOS. Taking into account differences in progesterone levels,...

Endometriosis and PCOS are both leading causes of female infertility, each affecting approximately 10% of reproductive-aged women worldwide. Both conditions markedly impair quality of life by affecting physical health, emotional well-being, mental health, and social functioning, and they impose a substantial economic burden through surgical treatments, assisted reproductive technologies, and work absenteeism. Insulin resistance (IR) plays a key role in the pathogenesis of both disorders by...

Background: For decades, the ketogenic diet has been successfully used for the treatment of obesity, metabolic syndrome, and type 2 diabetes. The mechanisms through which it affects metabolism are not fully understood, but the hormonal changes that occur during ketogenic nutrition are likely to play an important role. Objectives: To investigate the effect of the ketogenic diet on various hormones associated with obesity and the accompanying metabolic disorders in childhood. Methods: One hundred...

Polycystic ovary syndrome (PCOS) is an endocrinological disorder characterized by weight-loss resistance. Time-restricted eating (TRE) has become a popular weight-loss tool. However, the efficacy of TRE for weight management in PCOS remains understudied. We evaluated the effectiveness of TRE compared with standard care (daily calorie restriction (CR)) and a no-intervention control in women with PCOS. Seventy-six participants were randomly assigned to one of three groups for 6 months: a 6-hour...

Background/Objectives: Risk perception of future disease may play a role in supporting lifestyle change to prevent diabetes mellitus (DM) and cardiovascular disease (CVD). It is unknown how women in the postpartum period with different cardiometabolic conditions perceive their future risk of DM and CVD, and whether this perception influences engagement in a healthy lifestyle. Methods: Cross-sectional study of women who delivered in the past five years (n = 497) living in Australia. Logistic...
