Ajax Harwood Clinic
Anti-Mullerian hormone (AMH)
This test is useful only in specific situations — it's not right for everyone who asks about it.
What this test is
AMH is a hormone that reflects how many eggs you have left. Some call it an egg count test. It has real uses. Fertility clinics use it to plan treatment. It can also help diagnose PCOS. It is not a reliable way to guess your natural chance of pregnancy. This is true if you are not in fertility treatment. A large study followed almost 1,000 women trying to conceive. Women with low AMH got pregnant just as often as women with normal AMH. So a low result outside a fertility clinic can cause worry. It may not tell you much about your real fertility. If you are worried about your fertility, ask for a referral to a fertility specialist. That is a better first step than this test alone.
