Cryptorchidism in Mammals: A Review

Abstract

Cryptorchidism is seen more often in horses, cats, dogs, and pigs and rare in ruminant. It is believed to result from heredity, an autosomal recessive mode of inheritance or a dominant gene with the incomplete penetrance. Ruling out castration as well as conducting physical examinations can easily diagnose cryptorchidism. It can be controlled by complete castration or culling of the affected animal and where appropriate, the animal be used as food animal other than for breeding purposes.
