What is primary ovarian insufficiency (POI)?
Primary ovarian insufficiency (POI) is a term that is often used to mean the same thing as premature menopause, but it is different. POI happens when your ovaries stop working before age 40 and sometimes as early as in your teens. However, your ovaries may still make hormones and release eggs from time to time. You may get irregular menstrual periods, and you can still get pregnant. Learn more about POI.
