Chryptorchidism occurs when one or both testicles are retained in the abdomen and do not descend into the scrotum. Complications are common in cryptorchid dogs, but neutering will eliminate these problems.
Chryptorchidism is a common hereditary problem in dogs; for this reason, dogs with undescended testicles should not be bred. Other causes have not been determined.
Sperm are best produced just under normal body temperature. Chryptorchid dogs are usually unable to produce sperm due to the increased temperature inside the abdomen.
Chryptorchid dogs are 13 times more likely to develop testicular tumors. Since early diagnosis is difficult in chryptorchid dogs, neutering is highly recommended
Testicular torsion occurs when the spermatic cord twists, cutting off circulation to the testicle. In cryptorchid dogs, this may lead to abdominal pain and stiffness when walking.
Neutering for cryptorchid dogs is more invasive than a normal neuter. The abdomen is opened to locate the testicle for removal, and a longer recovery time is required.
