Glossary -   Premature ovarian failure (POF)



This is a condition in which the ovaries stop working too early (earlier than age 40). This causes the menstrual periods to stop. It is found only in about 1% of all women. It is sometimes caused by diabetes, other hormone disorders, autoimmune disorders, and can be a result of cancer treatments or other medications. It often occurs in women with galactosemia. Symptoms include hot flashes, mood swings, night sweats, vaginal dryness and infertility.
