Undescended Testicle (Cryptorchidism)

Boys' testicles develop in the abdomen prior to birth and typically descend to their normal position in the scrotum before birth. When a testicle cannot be found in the scrotum, it is considered undescended.

The condition occurs in up to 30 percent of premature boys, 4 percent of full term boys, and can be present on one side or both.

When a testicle cannot be found in the scrotum, it is considered undescended. This can occur because:

  • The testicle retracts easily
  • The testicle did not descend completely and is stuck higher in the groin or abdomen
  • The testicle was lost while still in the womb or before birth

Close examination by a pediatric urologist can help determine the position of the testicle and the appropriate treatment course. In many cases, the testicle will descend on its own in the first 3-6 months of life. In other cases, the position of the testicle can be corrected surgically.
