About the test
Anti-mullerian hormone (AMH) is a hormone that is produced by the ovaries. We check AMH as a marker of 'ovarian reserve', sometimes called the 'egg count'. Women are born with a high number of eggs contained within their ovaries and the number of these eggs decreases as a woman ages. AMH is a marker of the number of eggs that are left.
A lower than expected AMH for a woman's age may be a sign that the egg count is declining more quickly than expected and may mean it is more difficult to become pregnant.
A higher than expected AMH can occur in Polycystic Ovarian Syndrome and, rarely, in certain types of ovarian tumours.
