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.
Men who had an undescended testicle (called cryptorchidism) have a higher risk for testicular cancer. While a boy is in the womb, the testicles form in his abdomen. Normally they move down, or descend, into the scrotum before birth. Sometimes this doesnât happen and one or both testicles donât descend.
