Undescended testes (cryptorchidism) refers to abnormal descent of the testes into the scrotum. Normally the testes will descend into the scrotum during the third trimester of the pregnancy.This condition often self-corrects by six (6) months of age. Cryptorchidism (undescended testes) is influenced by age. The incidence in premature boys is about 9% to 30%; the incidence in male infants delivered at term is 3% to 6%.

“Retractile testes” are fully descended,but move freely between the scrotum and groin.Undescended testes must be surgically placed in the scrotum to maximize fertility and reduce the risk of testicular malignancy.

As the parent of a boy with undescended testes, regular exams with your Primary Care Provider or a Pediatric Urologist are important. Sometimes hormones are given to stimulate descent into the scrotum. Testes should be in the scrotum by 6 to 12 months of age to avoid the risk of decreased fertility or malignancy.
