More and more evidence indicates that PCOS may be a complex polymorphic disease, influenced by epigenetic and environmental factors, including diet and lifestyle. This review focuses on the role of the gut microbiota and its metabolites in PCOS, a topic that has gained significant attention recently due to the established link between the gut microbiome and metabolic disorders.
