Definition:
Anti-mullerian hormone, or AMH, is a protein released by the ovaries and is related to the development of follicles in the ovary. Blood work to check AMH levels may be done as a part of fertility testing.
AMH levels correspond to the number of antral follicles, which can be used to indicate the number of eggs available in the ovaries. A very low level of AMH may indicate poor ovarian reserves. A very high level of AMH may correspond to PCOS.
