Serum concentrations of anti-Müllerian hormone modulate ovarian response to different doses of follicle-stimulating hormone in Japanese Black donors.

Abstract

Anti-Müllerian hormone (AMH) is a marker for predicting embryo production in cows subjected to superovulation; however, it remains to be established as a reliable predictor of reproductive performance. We hypothesized that the serum AMH concentration of donors affects the ovarian response to follicle-stimulating hormone (FSH) treatment during superovulation. Herein, we retrospectively investigated the association between different FSH doses and AMH concentrations in donor Japanese Black cows in a superovulation program and analyzed the number of total and transferable embryos recovered. The number of transferable embryos recovered from donors with high AMH levels was significantly higher than that recovered from donors with low AMH levels. Additionally, it increased further with a reduction in the FSH dose. These results illustrate that the AMH concentration is a useful marker for predicting embryo production after superovulation, and donors with high AMH levels produce more transferable embryos at low FSH doses than at high doses.
