The testicles develop in the infant's abdomen as the baby grows in the womb. They drop down into the scrotum in the last months before birth.
In some cases, one or both testicles do not drop into the correct position. About half of these cases will descend within the first year of life without treatment.
Undescended testicle repair surgery is recommended for patients whose testicles do not descend on their own.
The surgery is done while the child is asleep (unconscious) and pain-free under general anesthesia. The surgeon makes a cut in the groin. This is where most undescended testes are located.
After finding the cord that holds the testis in the scrotum, the surgeon unties it from the tissue around it. This allows the cord to extend to its full length. A small cut is made in the scrotum, and a pouch is created. The testicle is pulled down into the scrotum, and stitched into place. Stitches are used to close the surgical cuts.
In some cases, the procedure can be done laparoscopically. This involves smaller surgical cuts.
When the testicle is located very high, correction may require two stages. Separate surgeries are done several months apart.
