What is it used for?An AMH test is often used to check a woman's ability to produce eggs that can be fertilized for pregnancy. A woman's ovaries can make thousands of eggs during her childbearing years. The number declines as a woman gets older. AMH levels help show how many potential egg cells a woman has left. This is known as the ovarian reserve.If a woman's ovarian reserve is high, she may have a better chance of getting pregnant. She may also be able to wait months or years before trying to get pregnant. If the ovarian reserve is low, it may mean a woman will have trouble getting pregnant, and should not delay very long before trying to have a baby.AMH tests may also be used to:Predict the start of menopause, a time in a woman's life when her menstrual periods have stopped and she can't become pregnant anymore.
