More to Know

A baby boy's testes (testicles) develop in his abdomen before birth. Usually, the testes drop, or descend, from the baby's abdomen into the scrotum shortly before birth. If this does not happen, the baby is born with undescended testis, also called cryptorchidism. Most cases involve one testicle, but occasionally both testes can be undescended.

Keep in Mind

If the testis doesn't drop to the usual location by the time a baby is 6 months old, surgery is required. Orchiopexy (or-kee-oh-PEK-see) is a common outpatient procedure to correct an undescended testicle (testis).
