Polycystic ovary syndrome（PCOS）is a common disease among adolescents and women of reproductive age，and its prevalence is as high as 5%~13%. PCOS is an important cause of anovulatory infertility，which often accompanied by reproductive en⁃docrine and glucose and lipid metabolism disorders. Individualized lifestyle interventions，drug therapy，targeted therapy for gut micro⁃biota and traditional Chinese medicine can improve glucose and lipid metabolism disorders and other clinical features in PCOS patients. Effective prevention and treatment of PCOS in women of youth and childbearing age is of great significance to the national strategy of eu⁃genics and postnatal care and the realization of our country’s balanced population development.
