The Anti-Müllerian Hormone (AMH) test is widely used in reproductive and hormone health. It helps provide key insights at different stages of life, from early development to adulthood.
Results are used to support medical decisions related to fertility, diagnosis, and treatment planning.
Anti-Müllerian hormone (AMH) is a substance made by the ovaries in women and the testicles in men.
In women, AMH is made by tiny sacs in the ovaries called follicles. These sacs hold immature eggs. AMH levels show how many eggs you might have left. This is called your ovarian reserve.
In men, AMH helps form the male reproductive organs before birth.
Doctors use AMH as a marker to check fertility, monitor ovarian conditions, and help understand hormone-related problems.

AMH is measured with a blood test. A small sample is taken from a vein in your arm. It takes only a few minutes.
This test is often done together with:
These tests help give a full picture of your hormone health. In fertility treatments like IVF, AMH levels are used to predict how your ovaries will respond to stimulation. This helps doctors choose the right medication dose and avoid over- or under-treatment.
Do you need to prepare?

AMH levels are measured in nanograms per milliliter (ng/mL) and must be interpreted based on age and sex.

High AMH means you may have more follicles than usual.
Common causes include:
Low AMH means fewer eggs in the ovaries. It may lower the chance of pregnancy.
Still, a very low AMH level does not mean you can’t get pregnant. It only shows the number of eggs left in the ovaries (your ovarian reserve). It does not measure egg quality or whether you are ovulating. Many people with low AMH can still conceive naturally or with help.
Common causes include:
While AMH testing is useful, it has limits:
If you are using hormonal birth control, AMH levels may appear slightly lower. This effect is usually temporary. Your doctor may recommend testing a few months after stopping birth control for the most accurate results.
