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 occurs in about 3–4 percent of all full-term male newborns and in about 21 percent of premature male babies. In about 90 percent of all cases of cryptorchidism, there is just one undescended testicle.
