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?

In plants, iron homeostasis and oxygen metabolism are strictly related, indeed several Fe-requiring enzymes catalyze reactions that also involve O(2) as a reagent, product, entry or end point of the pathway. Oxygen sensing itself relies on the Fe-dependent enzymes Plant cysteine oxidases. However, the impact of iron deficiencies on the response to hypoxic stresses has not been investigated so far. PCOs channel the ERFVII ethylene-responsive factors into a proteasomal N-degron pathway that...

CONCLUSION: From 1990 to 2021, global PCOS burden increased substantially, with marked socioeconomic and regional disparities. This underscores the need for enhanced screening, personalised treatments, and targeted interventions in low-SDI regions to promote reproductive health equity.

This study examined the role of miRNA-21-5p in a rat model of polycystic ovary syndrome with insulin resistance (PCOS-IR) and its potential involvement in ovarian granulosa cell apoptosis. Female Sprague-Dawley rats were divided into four groups, with the PCOS-IR model established using dehydroepiandrosterone combined with a high-sugar, high-fat diet. Lentiviral transduction was utilized to silence miRNA-21-5p. Serum hormone levels were assessed via ELISA, while the protein expression of PDCD4,...

CONCLUSION: Modulating the gut microbiome through diet is a promising, non-invasive, cost-effective strategy for PCOS management. By targeting insulin resistance, androgen excess, and inflammation, nutrition-based interventions can improve metabolic and reproductive outcomes. Long-term randomized trials are needed to strengthen causal evidence and guide personalized dietary approaches.

A case is reported of delayed ovarian torsion following controlled ovarian hyperstimulation and uncomplicated oocyte retrieval, further complicated by post-laparoscopic ipsilateral vulvar hematoma. A 37-year-old nulliparous woman with a history of polycystic ovary syndrome presented with clinical symptoms of ovarian torsion on post-retrieval day 8 and underwent laparoscopic detorsion. Her case was complicated by a large non-traumatic vulvar hematoma on post-laparoscopy day 1. Despite safe...

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a common endocrine disorder in women, associated with insulin resistance, ovulatory dysfunction, hyperandrogenism, and inflammation. Current treatments often focus on symptoms rather than underlying causes, emphasizing the need for comprehensive strategies. Recently, probiotics have emerged as a safe and cost-effective nutritional option for managing metabolic issues.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that involves metabolic, hormonal, and inflammatory changes. These changes can affect tissues with high metabolic needs and sensitive microvascular systems. Optical coherence tomography (OCT) and OCT angiography (OCTA) are non-invasive ways to assess the structure and blood vessels of the retina and choroid. However, studies on women with PCOS have shown mixed results. This systematic review and meta-analysis set out to combine and...
