Anti-Müllerian hormone (AMH)

Also called: AMH, Egg reserve test, Ovarian reserve test

AMH estimates how many eggs remain in the ovaries (ovarian reserve).

SampleA small tube of blood from a vein in your arm
Fasting?Usually not needed
ResultsSeveral days
Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.

What the test is

It doesn't predict whether you can get pregnant naturally right now. It helps plan fertility treatment.

Why it's done

  • Fertility evaluation or egg freezing
  • Possible PCOS (often high)
  • Possible early menopause (low)

Getting ready and what happens

  • Can be tested any day of the cycle.

How the test is done

  • A health worker cleans the skin, puts a band around your arm, and draws blood from a vein with a small needle. It takes a few minutes.

What the results mean

Low

Suggests fewer eggs. It's normal for AMH to fall with age.

High

Often seen with PCOS.

Questions to ask your provider

  • What do my results mean for me?
  • Do I need to repeat this test or have other tests?

Risks

A blood draw is very safe. You may have slight pain or a small bruise where the needle went in.
