Testes
The cat has two testicles, housed within the scrotum. Testicular diseases are uncommon in cats as many cats are neutered. In intact males, problems associated with the testicles include congenital abnormalities, such as cryptorchidism (testicle fails to descend into scrotum and is retained in the abdomen); infections; trauma; and tumors. Testicular tumors are rare in cats; however, cats with cryptorchidism have a higher incidence. Cats with testicular disease may present with a swelling in the scrotum or problems during breeding. Cats that will not be used for breeding should be castrated (surgical removal of the hormone producing testicles) to potentially cure the disease, prevent pet overpopulation, and avoid unwanted behaviors (e.g.: inter-cat aggression and roaming to find a mate).
