Undescended Testicles in Newborns. Cryptorchidism: Symptoms and Treatment
Cryptorchidism is when one or both male testes do not descend in the scrotal sac. This can happen with newborns who are full-term or born prematurely. According to the American Urological Association, undescended testes occur in about 3–5 percent of all full-term male newborns and in about 15–30 percent of premature male babies. In about 90 percent of all cases of cryptorchidism, there is just one undescended testicle.
