Premature Ovarian Failure

Premature ovarian failure is indicated when the normal function of the ovaries stops in a woman younger than age 40.
Premature Ovarian Failure Articles
You are considered to have premature ovarian failure (POF) if you are 40 years old or younger and your ovaries no longer ovulate (release eggs).
If your periods are irregular or have stopped, your doctor will ask you to have a blood test that measures the level of follicle stimulating hormone (FSH). FSH helps control a woman’s menstrual cycle and the production of eggs. This blood test helps determine whether or not your ovaries are working properly and is done on the third day of the menstrual cycle.
