Cryptorchidism is the failure of one or both testicles to descend into the scrotum. Bilateral cryptorchidism usually results in sterility but the abnormally descended testes can still produce sex hormones. Unilateral cryptorchidism is more common and the abnormal testicle can be located anywhere from near the kidney to within the inguinal ring. Cryptorchidism is an inherited condition so males with the condition should not be used for breeding purposes. Cryptorchid males are usually castrated because of the heritable nature of the condition and because the cryptorchid testicle is prone to developing tumors.
Surgical removal of the cryptorchid testicle is indicated. If an animal is castrated and the cryptorchid testicle is left behind, the cryptorchid testicle will continue to produce testosterone resulting in bull-like behavior even though the animal will be infertile. Additionally, cryptorchid testicles are at an increased risk of developing cancer or becoming twisted.
