AMH Test Explained: What Your Result Means for Fertility

AMH (anti-Müllerian hormone) is a blood test that estimates ovarian reserve — roughly how many eggs remain. It's useful context, but one number never tells the whole story.

What AMH measures

AMH reflects egg quantity, not egg quality or whether you can conceive naturally. It is produced by the small follicles in your ovaries, so it gives a snapshot of how many eggs are in reserve. Because levels stay fairly stable across the month, the test can be done on any day of your cycle. It cannot, however, predict exactly when menopause will arrive or guarantee a pregnancy in any given month.

Why a doctor might order it

AMH is commonly checked when a couple has been trying without success, before fertility treatment such as IVF to help plan the medication dose, when there is a family history of early menopause, or to investigate conditions like PCOS. It is one input into a wider picture rather than a stand-alone verdict on your fertility.

Interpreting results

• Higher AMH often means more eggs — common in PCOS
• Lower AMH suggests fewer eggs — more common with age
• A 'normal' AMH doesn't guarantee easy conception
• A low AMH doesn't mean natural pregnancy is impossible

Results are always read against your age. A younger person with a lower-than-expected AMH and an older person with an average AMH may be advised very differently. Labs also use different units and reference ranges, so compare your result only against the range printed on your own report.

Common misunderstandings

• A high AMH does not mean better egg quality — it often reflects PCOS
• A low AMH does not mean you cannot conceive naturally this month
• AMH is not a pregnancy test and cannot tell you the best time to try
• A single result can vary between labs, so don't over-read small differences

When to speak to a doctor

Discuss an AMH test with a doctor if you have irregular or absent periods, are thinking about delaying pregnancy, have had ovarian surgery or cancer treatment, or have been trying to conceive without success. A specialist will interpret AMH alongside your age, cycle history, an ultrasound (antral follicle count) and other hormone tests before suggesting any plan — so ask what your result means for your options, not just the number on the report.
