What is an Undescended Testicle?
During the development of a fetus, the testicles (male sex organs) form near the kidneys. As the fetus grows, the testicles descend (move down) into the scrotum. Normally, they’re in the scrotum before the baby is born. An undescended testicle doesn’t fully descend into the scrotum.
Common sites of an undescended testicle
Most often, the testicle stops descending between the groin and the scrotum. Sometimes it stops above the groin. Or it may stray off the normal pathway.
Locating an undescended testicle
Your child's healthcare provider can usually feel an undescended testicle during a physical exam. Your baby lies on his back for the exam. An older child may be asked to squat. The healthcare provider places his or her fingers on the child’s groin and then gently moves them toward the scrotum until the testicle is felt. If the testicle can’t be found with an exam, imaging studies, such as ultrasound, or other tests may be needed.
The healthcare provider will most likely wait for a few months to see if your son’s testicle will descend on its own. The closer the testicle is to the scrotum, the greater the chance it will come down. If the testicle does not descend on its own, it can still be treated. If both testicles have not descended, or if the testicle is above the groin, the healthcare provider may advise treatment.
Your child's healthcare provider may recommend a surgical repair to locate the undescended testicle and move it to the scrotal sac. This surgery, called orchiopexy, is usually done between months 6 and 9 months and is successful in 98% of children with this condition. Early intervention may preserve future fertility and may reduce risk of cancer.
