Undescended testicle (cryptorchidism) is a testicle that hasn't moved into its proper position in the bag of skin hanging behind the penis (scrotum) prior to the birth of a baby boy.            About 2 to 5 percent of baby boys are born with one or two undescended testicles. An undescended testicle is more common among baby boys born prematurely, or before 37 weeks. It's rare for boys with cryptorchidism to have two undescended testicles.                 For most boys born with one or two undescended testicles, the problem corrects itself within the first few months of life. If your infant has an undescended testicle that doesn't correct itself, surgery can usually be used to relocate it into the scrotum.                 Symptoms               Testicles form in the abdomen during fetal development. During the last couple of months of normal fetal development, the testicles gradually leave the abdomen, pass through a tube-like passageway in the groin (inguinal canal) and descend into the scrotum.              If your son has an undescended testicle, that process was stopped or delayed in some stage of development. Therefore, you won't see or feel a testicle where you would expect it to be in the scrotum.                       When to see a doctor                An undescended testicle is typically detected when your baby is examined shortly after birth. If your son has an undescended testicle, ask the doctor how often your son will need to be examined. If the testicle hasn't moved into the scrotum by the time your son is 4 months old, the problem probably won't correct itself. Treating undescended testicle when your son is still a baby may lower the risk of complications later in life, such as infertility and testicular cancer.      Older boys — from infants to preadolescent boys — who have normally descended testicles at birth may appear to be "missing" a testicle later. This condition may indicate:                 A retractile testicle, which moves back and forth between the scrotum and the groin and may be easily guided by hand into the scrotum during a physical examination                      An ascending testicle, or acquired undescended testicle, which has "returned" to the groin and cannot be easily guided by hand into the scrotum             If you notice any changes in your son's genitals or are concerned about his development, talk to your doctor.
