Anti-Mullerian Hormone Helps Assess Aging Mares’ Fertility

Equine researchers at the University of Kentucky (UK) have been chasing anti-Mullerian hormone (AMH, which is produced by cells in fetal testes as well as granulosa cells) for quite some time. They’ve determined they can use it to test for cryptorchidism in male horses as well as ovarian tumors in mares. Now, they’re trying to see if the hormone can predict an aging mare’s remaining follicle count.

Hormone Test Shows Fertility Potential

The anti-Müllerian hormone (AMH) is a substance produced by egg sacs in the ovaries, and a growing body of research suggests the level of the hormone is an indicator of fertility potential. Because egg supply, also known as ovarian reserve, is linked to chances of pregnancy, fertility doctors increasingly are using the AMH test to help determine treatment of fertility problems or help women plan pregnancy.
