A woman’s ovaries normally function until she is well into her 40s. Generally, menopause will begin around age 50. Unfortunately, some women experience primary ovarian failure. This condition can occur in women before they reach the age of 40.
Primary ovarian insufficiency, or POI, is the result of the ovaries not producing normal amounts of the hormone estrogen, or they do not release eggs regularly. Infertility is often the result.
POI is different from premature menopause, although the two are often confused. Women who experience premature menopause cannot get pregnant, while those with POI can still have irregular or occasional periods for years and may become pregnant.
Low estrogen levels in women with POI can produce other problems, such as osteoporosis. Restoring sufficient levels of estrogen can reverse these symptoms.
