Pediatric undescended testes (cryptorchidism - UDT)

Pediatric undescended testes (UDT) – also known as cryptorchidism – means that a testicle hasn’t moved into its proper position in the scrotum before birth.

What are pediatric undescended testes (cryptorchidism - UDT)?

The testicles are formed in the abdomen before your baby is born. While the baby is developing, the testicles follow a pathway from the abdomen through the groin and into the scrotum.  

In up to 5% of boys, the testicle does not complete this journey and this results in a testicle that is not in the scrotum and is located somewhere along this path, possibly still in the abdomen.

What are the signs and symptoms of pediatric undescended testes (cryptorchidism - UDT)?

  • Not seeing or feeling a testicle where you would expect it to be in the scrotum

  • Swollen lymph node (small, bean-shaped gland) in the groin

How are pediatric undescended testes (cryptorchidism - UDT) diagnosed?

Physical exam - An undescended testicle (UDT) is usually detected by the parents or your pediatrician as an empty scrotum on exam. Your child's provider will likely attempt to determine whether they can feel the testicle in the groin canal. If not, it is possible that the testicle is still in the abdomen.   

An ultrasound may be helpful in finding the testicle that cannot be felt.
