Anti-Mullerian hormone (AMH), also known as Mullerian-inhibiting hormone (MIH), is a glycoprotein hormone structurally related to inhibin and activin from the transforming growth factor beta superfamily, whose key roles are in growth differentiation and folliculogenesis.

In humans, the gene for AMH is AMH, on chromosome 19p13.3,
while the gene AMHR2 codes for its receptor on chromosome 12.
AMH can be used for selection of females in multi-ovulatory embryo transfer programs by predicting the number of antral follicles developed to ovulation.
AMH can also be used as a marker for ovarian dysfunction, such as in women with polycystic ovary syndrome (PCOS).
