Undescended testicle. Close-up of an undescended right testicle (testis, left) in a 9-year-old boy. This condition occurs in about 1% of full-term babies and up to 10% of premature babies, usually affecting only one testis. If the testis does not descend of its own accord within several months of birth the condition can become permanent as the blood vessels and spermatic cord do not lengthen sufficiently. The undescended testis then fails to develop properly and will not be able to produce sperm in adulthood. The most effective treatment is a surgical procedure called orchiopexy, in which the undescended testis is lowered into the scrotum.
