Hypospadias is a congenital anomaly in which the urethral opening is at the base of the penis, or along the inferior aspect of the shaft of the penis. Hypospadias is usually associated with an abnormal curvature of the penis, called "chordee". Hypospadias is one of the most common birth defects seen in infant boys. Surgery is necessary to allow normal urination, to correct the penis deformity, and to ensure normal sexual functioning. The repair is performed before the child reaches school age.
