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?

CONCLUSION: HA-PCOS is marked by more severe metabolic disruption. Irisin may serve as a promising early biomarker for this phenotype and help predict long-term complications linked to metabolic disruption in PCOS.

Mammalian reproductive function is dependent upon gonadal steroid hormone feedback within the hypothalamic-pituitary-gonadal (HPG) axis. In polycystic ovary syndrome (PCOS), impaired progesterone (P4) negative feedback leads to hyperactive pulsatile secretion of luteinising hormone (LH) and impaired reproductive function. Although the precise upstream neuronal network modulating P4 negative feedback remains undefined, gamma-aminobutyric acid (GABA)ergic neurons in the arcuate nucleus (ARC) have...

Accurate quantification of circulating androgens, particularly the biologically active free fraction, is analytically challenging due to ultra-low concentrations and extensive protein binding in human serum. Here, we developed and validated an integrated ultrafiltration-LC-MS/MS workflow for simultaneous quantification of nine endogenous serum free androgens. Free fractions were isolated by phosphate-buffered saline dilution followed by temperature-controlled centrifugal ultrafiltration (37 °C)...

5α-androstane-3α,17β-diol 17-glucuronide (3α-diol G) is a testosterone metabolite and an important biomarker of hormonal dysregulation, including polycystic ovary syndrome (PCOS) and virilizing syndromes in women such as idiopathic hirsutism. While immunoassay kits are commonly used for its quantification in clinical laboratories, these methods are prone to interference due to the structural similarity among steroidal compounds. In this study, we developed and validated a robust LC-MS/MS method...

Polycystic ovary syndrome (PCOS) is a prevalent and heterogeneous endocrine-metabolic disorder affecting women of reproductive age, characterized by elevated androgen levels, disrupted ovulation, and polycystic ovarian changes. Increasing evidence indicates that oxidative stress and ferroptosis contribute to granulosa cell dysfunction and ovarian impairment in PCOS. In this study, we identified sestrin 2 (SESN2), a stress-inducible metabolic regulator, as a protective factor against ferroptosis...

ABSTRACT: Polycystic ovary syndrome (PCOS) is a multifactorial disorder traditionally recognized for its endocrine and metabolic disturbances. However, accumulating evidence indicates that chronic low-grade inflammation and immune dysregulation play a central role in its pathophysiology. This narrative review explores the immunological mechanisms underlying PCOS and their repercussions for reproductive outcomes. Women with PCOS exhibit increased circulating levels of inflammatory...

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder characterized by reproductive and metabolic disturbances, which causes a chronic lack of ovulation that leads to increased incidence of atypical endometrial hyperplasia and carcinogenesis. Increasing evidence indicates that metabolic changes may play a crucial role in PCOS pathogenesis; however, the metabolic profile of fluid in PCOS-related endometrium has not yet been characterized. In this study, we successfully constructed...

Accurate and efficient detection of multiple diseases from diagnostic images remains a major challenge in today's world, especially in women's health conditions such as breast cancer, cervical cancer, and Polycystic Ovary Syndrome (PCOS). Each of these diseases presents its own unique imaging characteristics and visual patterns, making detection of these diseases all together through a single model is highly challenging. In this respect, in order to overcome this, we have proposed a hybrid deep...

CONCLUSIONS: Oral microbiota alterations in PCOS are characterized by consistent Fusobacterium elevation and heterogeneous changes associated with systemic inflammation, metabolic‒endocrine disturbances and poor periodontal health. Despite the limited current evidence, the oral microbiota may serve as a novel entry point for PCOS management. Large, high‑quality prospective studies are warranted to clarify the causal relationship between the oral microbiota and PCOS, and to explore the...

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: Menstrual irregularity is a hallmark clinical feature of polycystic ovary syndrome (PCOS), which is an established risk factor for spontaneous abortion. However, robust population-level evidence directly linking specific patterns of menstrual irregularity to spontaneous abortion risk remains lacking, as prior studies have been limited by small sample sizes.

CONCLUSIONS: PCOS women had comparable depression and FertiQoL scores and lower levels of anxiety and stress when compared to non-PCOS women. Longer duration of infertility and obesity were associated with depression and lower quality of life irrespective of cause.
