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.
This is called undescended testicles or cryptorchidism.. In such cases, pediatricians usually wait and watch. Quite often, the testicles descend on their own (3%-5% of boys are born with this; by 6 months, only 0.8% still have an undescended testicle without any intervention). If, by 6 months or so, the testicle still can't be felt, you may want to consult with a pediatric urologist.
