You may need an AMH test if you are a woman who is having difficulty getting pregnant. The test can help show what your chances are of conceiving a baby. If you are already seeing a fertility specialist, your doctor may use the test to predict whether you will respond well to treatment, such as in vitro fertilization (IVF).

High levels may mean you may have more eggs available and will respond better to treatment. Low levels of AMH mean you may have fewer eggs available and may not respond well to treatment.

You may also need an AMH test if you are a woman with symptoms of polycystic ovary syndrome (PCOS). These include:

Menstrual disorders, including early menopause or amenorrhea
Acne
Excess body and facial hair growth
Decreased breast size
Weight gain

In addition, you may need an AMH test if you are being treated for ovarian cancer. The test can help show if your treatment is working.

A high level of AMH may also mean you have polycystic ovary syndrome (PCOS). There is no cure for PCOS, but symptoms can be managed with medications and/or lifestyle changes, such as maintaining a healthy diet and waxing or shaving to remove excess body hair.

A low level can mean you may have trouble getting pregnant. It can also mean that you are starting menopause. A low level of AMH is normal in young girls and in women after menopause.
