With premature menopause, your periods stop before age 40. You can no longer get pregnant. The cause can be natural or it can be a disease, surgery, chemotherapy, or radiation.

Later symptoms may be similar to those of natural menopause:</p> <ul> <li>Hot flashes</li> <li>Night sweats</li> <li>Irritability</li> <li>Poor concentration</li> <li>Decreased sex drive</li> <li>Pain during sex</li> <li>Vaginal dryness</li> </ul> <p>Doctors diagnose POF by doing a physical exam and lab and imaging tests.</p> <p>Most women with POF cannot get pregnant naturally. Fertility treatments help a few women; others use donor eggs to have children. There is no treatment that will restore normal ovarian function. However, many health care providers suggest taking hormones until age 50. </p> <p >NIH: National Institute of Child Health and Human Development</p>|HPO2016_07_04:Malfunctioning of the ovaries such that a girl never begins menstruation.
