Equine AMH

Anti-Mullerian Hormone (AMH) is produced by granulosa cells in the equine ovary and in normal mares this level is very low (usually less than 1.0 ng/mL). AMH levels in normal mares do not significantly change during oestrus or pregnancy, unlike Inhibin, and this makes it clinically more useful in these cases.

Mares with GCTs have greatly increased levels of AMH (usually greater than 25ng/mL) and this makes it a very useful diagnostic tool in addition to Inhibin to detect the presence of GCTs. AMH analysis is especially important in pregnant or cycling mares where Inhibin and Testosterone levels are often raised as part of the normal cycle and in pregnancy.

We offer AMH analysis on its own, with Inhibin or as part of our GCT Profile Plus which includes AMH and Progesterone.
