Is it normal for baby to be born with undescended testicles?

When baby boy is in his mommy's womb, his testicles typically form inside his abdomen and descend into the scrotum shortly before birth. In some cases, the descent doesn't occur, and the baby is born with a condition known as undescended testicles, or medically known as cryptorchidism. Cryptorchidism is the most common genital abnormality in boys, affecting approximately 30% of baby boys born prematurely and about 4% born at term. In about half of the babies, the undescended testicles move down on their own by the sixth month of life. If descent doesn't happen by then, it is imperative to get treatment because testicles that remain undescended may be damaged. This could affect fertility later or lead to other medical problems when the baby boy grows older. http://kidshealth.org/en/parents/cryptorchidism.html
