Changes in peripheral anti-Müllerian hormone concentration and their relationship with testicular structure in beef bull calves

The aim of this study was to clarify the time-course of changes in anti-Müllerian hormone (AMH) and testosterone (T) concentrations in peripheral blood, and to determine the relationships between blood AMH concentration and testicular development during the early postnatal and prepubertal periods in beef bull calves. A total of 17 Japanese Black bull calves were enrolled in this study. The week in which the calf was born (within 6 d after birth) was defined as M 0. Blood samples were taken once every month from M 0 to M 6 from each bull calf, and plasma AMH and T concentrations were determined.
