What is POI?
Many women naturally experience reduced fertility when they are around 40 years old. This age may mark the start of irregular menstrual periods that signal the onset of menopause. For women with POI, irregular periods and reduced fertility occur before the age of 40, sometimes as early as the teenage years.3,4
In the past, POI used to be called “premature menopause” or “premature ovarian failure,” but those terms do not accurately describe what happens in a woman with POI. A woman who has gone through menopause will never have another normal period and cannot get pregnant. A woman with POI may still have periods, even though they might not come regularly, and she may still get pregnant.2,4
