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.

Locating an Undescended Testicle
The undescended testicle can usually be felt during a physical exam. Your baby lies on his back for the exam. An older child may be asked to squat. The doctor 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 special tests may be needed.
The doctor 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 doctor may advise treatment.
