What is AMH and what does it tell you?

Bottom lineAMH (anti-Mullerian hormone) reflects your ovarian reserve, a rough estimate of egg quantity, and is most useful for predicting IVF response; it cannot tell you egg quality, your monthly chance of natural conception, or an exact egg count. Per ASRM it's a poor predictor of natural fertility, so treat AMH as one input for a clinician rather than a fertility score, mainly useful for IVF planning.

AMH (anti-Mullerian hormone) is made by the cells around your developing egg follicles, so its level roughly reflects your ovarian reserve - the number of eggs you have left. It's the headline at-home and clinic fertility test.

What AMH can tell you

• A rough estimate of your egg quantity (ovarian reserve)
• How your ovaries might respond to IVF stimulation - its most useful, evidence-backed use in fertility clinics

What AMH cannot tell you

• Your egg quality
• Your monthly chance of conceiving naturally
• An exact egg count or your "fertility score"

The American Society for Reproductive Medicine notes ovarian-reserve markers are poor predictors of natural fertility in women without a known infertility problem. A 2024 study of 3,150 women found low AMH (under 1 ng/mL) was only modestly linked to a longer time to pregnancy.

How to interpret a result

Treat AMH as one input for a clinician, not a verdict. A reassuring number doesn't guarantee fertility, and a low one doesn't mean you can't conceive.

When it's useful

Mainly for IVF planning and fertility counseling, especially with age or before treatment.
