Diagnostic criteria for PCOS were recently revised by the Japan Society of Obstetrics and Gynecology based on a nationwide survey of PCOS and released on December 5, 2023 (JSOG2024). JSOG2024 criteria diagnosed PCOS according to the following three items: (1) irregular menstrual cycle/chronic anovulation, (2) polycystic ovarian morphology or elevated serum anti-Müllerian hormone (AMH) level, and (3) hyperandrogenism or high luteinizing hormone. The presence of all three items is required to diagnose PCOS, after excluding other diseases with symptoms similar to PCOS. We also established AMH cut-off values by age and a system for evaluating ovarian findings useful for both the JSOG2024 and Rotterdam criteria.
