Undescended testicles is when your child’s testicles are not in their usual place in the scrotum. While your child is in the womb, the testicles are developing inside his abdomen. Towards the end of pregnancy, the testicles travel through a passage into the scrotum. Both testicles should be in the scrotum by the time your child is one year old.
Generally, only one of the testicles is affected, but on rare occasions, both testicles fail to travel to the scrotum.
