Polycystic ovary syndrome is a common reproductive endocrine metabolic disease in clinic. Professor Fengjie He has accumulated rich clinical experience in the process of diagnosis and treatment of the disease. He believes that the key to the pathogenesis of the disease is the dysfunction of the reproductive axis of “kidney - Tiangui - Chongren – uterus,” which is based on kidney deficiency and involves the liver and spleen. Clinically, patients with kidney deficiency and liver depression are common. The treatment takes tonifying the kidney and regulating the menstrual cycle as the main method, and the clinical effect is very effective.
