[Life-cycle management of polycystic ovary syndrome].

The pathogenesis of polycystic ovary syndrome (PCOS) is complex. The core features are ovarian hyperandrogenism caused by hypothalamus-pituitary-ovarian (HPO) axis dysfunction and hyperinsulinemia caused by insulin resistance. Common clinical manifestations include menstrual disorder, infertility, hyperandrogenism, polycystic ovarian morphology, etc., which can be accompanied by obesity, insulin resistance, dyslipidemia, and other metabolic abnormalities. They are high-risk factors for type 2 diabetes, cardiovascular diseases, and endometrial cancer. Comprehensive intervention measures are crucial to reduce the occurrence of PCOS and its complications. Early identification, early intervention, and reduction of metabolic dysfunction are important means of PCOS life-cycle management.
