Hypospadias is a common birth defect of the penis. The urethra (the tube that carries urine from the bladder to outside of the body) is not located at the tip of the penis. It can be located anywhere on the undersurface of the penis to the scrotum.
A condition called chordee is frequently associated with hypospadias. Chordee is an abnormal downward curve of the penis. This can occur with or without a hypospadias.
Classification of hypospadias is done by the position of the urethral opening. Most often the opening is found near the head of the penis. This is known as distal or glanular hypospadias. When it is located from the middle to the lower shaft of the penis, it is called midshaft hypospadias. When the opening is on the scrotum it is called penoscrotal and when it is behind the scrotal sac it is called perineal. These are the most severe forms of hypospadias.
