Abstract:

Intestinal microbiota is considered as an endocrine organ of the human body. Intestinal microorganisms and their metabolites can participate in human metabolism, immunity, reproduction and other aspects by affecting distant organs and related biological pathways. Intestinal microbiota imbalance plays an important role in the occurrence and development of diseases. Polycystic ovary syndrome (PCOS) has complex pathophysiological processes such as hyperandrogenism, hypothalamic-pituitary-ovarian axis disorders and insulin resistance. Related studies have shown that the intestinal microbiota of PCOS patients and PCOS rodent model is altered, and intestinal microbiota imbalance can lead to disturbances in sex hormone synthesis and insulin secretion and abnormal follicle development by mediating glucocorticoid metabolism, bile acid metabolism and chronic inflammation, suggesting that intestinal microbiota imbalance may play a corresponding role in the development and pathology of PCOS. This review highlights the role of intestinal microbiota imbalance in the pathogenesis of PCOS.
