AMH localizes to the rough endoplasmic reticulum in developing bovine Sertoli cells, with expression peaking during fetal and early neonatal development.

Does not support clinical translation; leaves open AMH's role in Sertoli cell maturation across species.
Anti-Müllerian hormone (AMH) was localized in Sertoli cell cytoplasm of male fetal and neonatal calves by an immunocytochemical technique using a monoclonal antibody directed against bovine AMH. At the ultrastructural level, AMH accumulates in the cisternae of the rough endoplasmic reticulum, but is not detected in the Golgi apparatus or in secretion granules. In the fetus, the immunocytochemical reaction for AMH appears at 43 days postcoitum in differentiating seminiferous tubules, plateaus from 50 days postcoitum to 8 days post partum, and subsequently decreases to become barely detectable in the testis of the 3-month-old calf. This chronological evolution is in keeping with previous studies of testicular anti-Miillerian activity.
