Anti‑Müllerian Hormone (AMH)

What is Anti-Müllerian Hormone (AMH)?

Anti-Müllerian Hormone (AMH) is a hormone produced by the reproductive organs and is an important indicator of fertility. In women, it indicates the size of the ovarian reserve, which can help in assessing fertility and planning family expansion. In men, AMH is produced in the testicles and plays a role in testicular development and sperm production.

Why test for Anti-Müllerian Hormone?

Testing AMH levels can be useful for people who wish to assess their fertility or are experiencing difficulties conceiving. In women, it can assist in understanding conditions such as polycystic ovary syndrome (PCOS) or early menopause. In men, it can provide insight into sperm production and testicular function.

What does it indicate?

AMH levels provide an indication of ovarian reserve in women, which can help in predicting the response to fertility treatments and assessing the time until menopause. In men, the AMH value can point to testicular health and sperm production capacity.

What does a high AMH level mean?

In women, a high AMH level indicates a good ovarian reserve, suggesting potentially higher fertility. However, very high levels may also point to PCOS. In men, high levels may be normal but should be assessed in the context of other tests.

What does a low AMH level mean?

A low AMH level in women may indicate a diminished ovarian reserve, which can suggest reduced fertility and approaching menopause. In men, a low level may indicate reduced sperm production or testicular dysfunction.
