Endocrinol."],"abstract":"<jats:p>(PCOS), one of the most common endocrine and metabolic disorders in women of reproductive age, has a complex pathogenesis that continues to be unraveled by ongoing research. The condition is defined by three key features: hyperandrogenemia, ovulatory dysfunction, and insulin resistance. Recent studies have highlighted the gut microbiome and its metabolites as crucial regulators in PCOS development. Evidence suggests that gut dysbiosis and intestinal barrier dysfunction play a pivotal role in the onset and progression of PCOS. This review comprehensively examines the central role of gut microbiota in PCOS pathogenesis, including shifts in microbial communities such as bacteria, fungi, and viruses, and their impact on critical metabolites like short-chain fatty acids, bile acids, and tryptophan metabolites, which modulate host metabolism and reproductive function. Furthermore, based on mechanistic insights, the review explores targeted gut microbiota interventions, systematically evaluating clinical evidence for dietary modifications, probiotic\/prebiotic supplementation and fecal microbiota transplantation. These approaches provide novel perspectives for precision medicine in PCOS treatment. The findings not only deepen our understanding of PCOS pathogenesis but also establish a strong theoretical foundation for innovative microbiome-based therapeutics.<\/jats:p>","DOI":"10.3389\/fendo.2026.1747766","type":"journal-article","created":{"date-parts":[[2026,4,13]],"date-time":"2026-04-13T04:46:39Z","timestamp":1776055599000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Gut
