[Persistence of Mullerian ducts in the male rabbit by passive immunization against anti-mullerian hormone during fetal life].

A female Rabbit immunized against bovine anti-Müllerian hormone (AMH) was mated and gave birth to 3 litters, containing a total of 13 males. Ten of these presented with Müllerian derivatives, of variable development. Testicular position and structure, Wolffian development and virilization of the urogenital sinus were apparently normal in males with persistent Müllerian ducts.
