Hypospadias

Hypospadias is the most common congenital anomaly of the penis. In this uretheral opening is situated on ventral side of the shaft of penis in one or several positions. Just behind the glans, on the body of penis or on the perineum.

There is an associated congenital chordae, caused by a fibrous band of tissue that extends from the scrotum up to the penis and pulls it ventrally in an area where the ventral foreskin is absent. Meatal stenosis, undescended testes, and inguinal hernia may be present. In case of severe hypospadias with chordae, it may be difficult sometimes to differentiate the sex of the neonate. There are varying degree of severity. depending on the position of urethral mentus. This may be on the gians (glandular hypospadias); at the corona (coronal hypospadias); on the shaft (penile hypospadias); at the junction of the shaft and the scrotum (penoscrotal hypospadias); and of the perineum (perineal hypospadiasj. The  penis is also usually curved downwards which is more marked during erection. This chordae is due to fibrosis between the urethral meatus and the glans. causing a ventral curvature. Other abnormalities are associated with hypospadias, such as deficiency in the ventral segment of the prepuce which causes a dorsal hood of redundant skin.
