History and Symptoms
The condition varies in severity. In most cases, the opening of the urethra is located near the tip of the penis on the underside. More severe forms of hypospadias occur when the opening is at the midshaft or base of the penis. Occasionally, the opening is located in or behind the scrotum.
Males with this condition often have a downward curve (ventral curvature or chordee) of the penis during an erection. (Erections are common with infant boys.)
Other symptoms include:
- Abnormal spraying of urine
- Having to sit down to urinate
- Malformed foreskin that makes the penis look "hooded"
Associated Birth Defects
Mild hypospadias most often occurs as an isolated birth defect without detectable abnormality of the remainder of the reproductive or endocrine system. However, a minority of infants, especially those with more severe degrees of hypospadias will have additional structural anomalies of the genitourinary tract. Up to 10% of boys with hypospadias have at least one undescended testis, and a similar number have an inguinal hernia. An enlarged prostatic utricle is common when the hypospadias is severe (scrotal or perineal), and can predispose to urinary tract infections, pseudo-incontinence, or even stone formation.
Epispadias
A much rarer and unrelated type of urethral malformation is an epispadias. This is not a problem of the urethral groove or meatus, but a failure of midline penile fusion much earlier in embryogenesis. An isolated opening of the dorsal side of the penis is rare, and most of these children have much more severe defects, involving a small and bifid phallus with bladder exstrophy or more severely, cloacal exstrophy involving the entire perineum. The cause of this defect of early embryogenesis is unknown but does not involve androgens.
