Undescended testicles (also known as cryptorchidism) is a condition in which one or both of a baby boy's testicles (testes) have not moved down into their proper place in the scrotum.
If your pediatric provider is completely unable to locate one or both, they may still reside in the abdomen and not have made the normal descent into the scrotum in the last trimester. This is called undescended testicles or cryptorchidism.. In such cases, pediatricians usually wait and watch.
