Understanding your AMH test: what the number really means
AMH is one of the most talked-about fertility tests, and one of the most misunderstood. Here's what it can and can't tell you.

AMH (anti-Müllerian hormone) is a simple blood test, and it often causes a lot of anxiety. A low number can feel frightening. But AMH tells only part of the story.
What AMH measures
AMH is made by the small follicles in the ovaries. Its level gives an estimate of your egg reserve, roughly how many eggs remain.
What AMH doesn’t tell you
- Egg quality. That depends mainly on age, not AMH.
- Whether you can conceive naturally. Many women with low AMH get pregnant without treatment.
- An exact “fertility deadline”. It’s a guide, not a countdown.
Why we still test it
AMH is very useful for planning treatment. It helps predict how the ovaries may respond to stimulation in IVF or egg freezing, so the medicine dose can be set more accurately and more safely.
If your AMH is low
Don’t panic. Speak to a specialist who will look at your AMH together with your age, ultrasound findings and overall health. A low AMH may mean it’s worth acting sooner. It doesn’t mean it’s too late.
If your AMH is high
A high AMH is often seen with PCOS. It’s useful to know, because it means stimulation needs to be gentler to avoid an over-response.
