Effects of induced cryptorchidism in bulls.
Ninety bull calves were made cryptorchid by forcing the testes into the abdominal cavity and ablating the scrotum with elastrator rings. Normal spermatogenesis was seen following histological examination of some of the testes approximately 17 months after the operation. No effect on bull behaviour was noted in the cryptorchids although plasma testosterone levels were lower than those reported for bulls. It is possible that this method may leave some of the cryptorchids fertile.
