Disorder - CryptorchidismOrgan Systems Involved
A disorder in which one or both testes fail to descend into the scrotum.
The testes are formed in the abdomen and usually move down into the scrotum by two to four months of age. Testes can fail to descend on one or both sides and are found in either the abdomen or in the groin. Testes that are retained in the abdomen are subject to higher temperatures than those in the scrotum, and for this reason do not function normally. Therefore if both testes are retained, the dog is usually infertile. Dogs with only one retained testis, however, are usually fertile. Dogs with retained testes are more prone to testicular cancer, even in the normally located testis, therefore in these dogs removal of both testes (castration) is recommended.
