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.

OBJECTIVE: MOTS-c is a mitochondria-derived peptide associated with reduced insulin resistance and obesity. The m.1382A>C polymorphism of the MOTS-c gene is linked to an increased risk of type 2 diabetes in men. However, no studies have explored the relationship between this polymorphism and MOTS-c levels in adolescents with polycystic ovary syndrome (PCOS). This study aimed to investigate the differences in MOTS-c levels between adolescents diagnosed with PCOS and those without PCOS, as well as...

CONCLUSIONS: Women with PCOS exhibit higher adiposity, particularly reflected by FM index and F/L ratio, which show closer associations with metabolic and inflammatory dysfunction than trunk FM. These findings support the potential use of BIA as an accessible, low-cost, and noninvasive tool for the cross-sectional assessment of metabolic dysfunction in PCOS. Longitudinal studies are needed to clarify the clinical relevance of these associations.

Background and aim Gestational diabetes mellitus (GDM) affects 6-15% of pregnancies globally and is traditionally diagnosed at 24-28 weeks of gestation. Early identification of high-risk women during the first trimester could enable timely interventions and improved pregnancy outcomes. This study aimed to develop and evaluate machine learning models for early GDM prediction using first-trimester clinical and laboratory parameters. To achieve this aim, the study has the following five key...

Microplastics pollution is a widespread environmental issue in Latin America and the Caribbean (LAC), where factors such as urbanization, insufficient waste management, and coastal vulnerability may increase exposure risks. Microplastics can act as carriers for endocrine-disrupting chemicals (EDCs), but a comprehensive synthesis of region-specific evidence linking this contamination to reproductive health outcomes has been lacking. This systematic review examines the evidence regarding the...

Polycystic ovary syndrome (PCOS) is a prevalent reproductive endocrine disorder in women. While the role of androgens in PCOS is well-recognized, the underlying mechanisms warrant further investigation. In this study, we identified potential hub androgen-related genes (ARGs) in PCOS and established diagnostic and classification models to find novel biomarkers for PCOS therapy. Five datasets (GSE34526, GSE80432, GSE95728, GSE124226, and GSE137684) were retrieved from GEO, followed by data...

Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder affecting women of childbearing age. Infertility caused by ovulatory disorders and low follicle quality is an urgent problem. Abnormal fatty acid oxidation (FAO) contributes critically to the etiology and progression in PCOS. However, the potential mechanism by which FAO affects follicular development in PCOS patients is unclear. Here, we demonstrate that increased expression of tripartite motif-containing protein...

CONCLUSION: Genetic and transcriptomic evidence jointly support the concept of a myeloid-inflammation axis in PCOS. The inverse MR association for absolute monocyte count alongside positive risk for CD33^(+)HLA-DR^(+) compartments, together with cross-cohort evidence of myeloid enrichment and inflammatory pathway activation, is compatible with a potential mechanistic link between immune imbalance and PCOS and provides a hypothesis-generating framework for future therapeutic investigation.

CONCLUSION: Offspring of women with PCOS exhibited early cardiometabolic and reproductive alterations in young adulthood, characterised by reproductive hormonal abnormalities in daughters and a less favourable cardiometabolic profiles in sons. While insulin sensitivity is largely preserved, subtle impairments in β-cell secretory function emerge after accounting for central adiposity in both sexes. These findings highlight the relevance of early cardiometabolic and reproductive assessment in this...

Lead (Pb), a ubiquitous environmental pollutant, contributes to the development of various diseases. But little information is available regarding its effect on polycystic ovary syndrome (PCOS) that is the main cause of female infertility. Here, we discovered that Pb exposure replicated the PCOS-like phenotypes in mice via the advancement of ovarian inflammatory response. After transferring to the mitochondria, Pb disrupted the interaction of Mn^(2+) and SOD2, and then decreased the enzymatic...

CONCLUSION: The combination of BHF and conventional medications significantly improved pregnancy and ovulation rates, as well as endometrial thickness, in PCOS patients compared to conventional treatment alone. This suggests that BHF could serve as a complementary therapy for infertility in PCOS patients. However, these findings should be interpreted with caution due to significant heterogeneity and methodological limitations in the included studies.

Polycystic ovary syndrome (PCOS) is increasingly recognized as a disorder of impaired immune-endocrine homeostasis. Emerging evidence indicates that intestinal dysbiosis and microbial metabolite imbalance can activate pattern recognition receptors (PRRs), forming a PRR microbiota reproductive axis that contributes to PCOS pathophysiology. This review synthesizes current insights into how gut-derived signals, including LPS, peptidoglycans, SCFAs, bile acids, and tryptophan metabolites, modulate...

Hyperandrogenism and elevated thioredoxin-interacting protein (TXNIP) are potential causes of infertility in women with polycystic ovary syndrome (PCOS). Epigenetic regulation of TXNIP mediates oxidative stress and inflammatory activation. However, the precise mechanisms including epigenetic regulation in PCOS are poorly understood. In this study, aberrant TXNIP in dehydroepiandrosterone (DHEA)-induced rat PCOS ovaries and dihydrotestosterone (DHT)-induced PCOS primary granulosa cells (GCs)...

CONCLUSIONS: For PCOS patients, live birth success is equivalent regardless of COS/FET protocol combination, supporting flexible treatment personalization. Clinical decision-making involves a critical trade-off: GnRH agonist protocols and ovulation FET cycles may be associated with a trend toward lower obstetric morbidity, potentially linked to the promotion of a more physiological ovulatory milieu. This balance between immediate iatrogenic risk and long-term pregnancy health warrants further...
