FXPOI causes symptoms similar to other types of ovarian insufficiency.1 These symptoms can include:
- Irregular menstrual periods (meaning that they may be infrequent, absent, or unusually light)
- Unusually short (less than 21 days) or long (more than 35 days) menstrual cycles
- Infertility—problems conceiving and/or carrying a pregnancy to term
- Symptoms of menopause, such as hot flashes, night sweats, and vaginal dryness
- Early menopause, sometimes before age 40—or even younger.1
