Hypospadias is a congenital disorder of the penis, an abnormality that may affect up to 1 out of every - male infants. Instead of having a urethral opening at the end of the penis, boys born with hypospadias have an opening on the underside of the shaft of their penis. If this causes a problem with urination, the condition can be surgically corrected. Surgery is most often performed before the child reas school age. The surgery involves creating a tube to extend the urethra to the end of the penis.
