Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic abnormality commonly seen in women of reproductive age. It is characterized by chronic anovulation (disturbance or loss of ovulatory function) and hyperandrogenemia (excess production of male hormones in a woman’s body), with the main clinical manifestations being irregular menstrual cycles, infertility, hirsutism and/or acne, and is the most common female endocrine disorder. Today, I will talk about the evidence-based treatment of polycystic ovaries from a TCM perspective.
