Testicular descent and enlargement of the gubernaculum is probably hormonally controlled by androgens from the testes or andrenals. Failure of normal testicular descent appears in most cases to be genetic in nature and results in cryptochidism, seenmost commonly in pigs, horses and dogs and least commonly in cattle, sheep and cats. Cryptorchidism is a recessive character in goats and sheep (Roberts, 1971). An abnormal development of the gubernaculum could account for cryptorchidism (Wensing, 1968).Unilateral crytorchidism usually results in nearly normal fertility because of normal sperm production from the testis located in the scrotum. The undescended testis may be located anywhere from just caudal to the kidney or within the inguinal canal. (McEntee,1969).
