What are hypospadias and epispadias?
Hypospadias and epispadias are birth anomalies that result from defective development of the penis during embryological development. Normally the urethra (the tube that serves as a conduit through the penis for passage of urine and semen) runs the entire length of the penis, forming an opening at the tip. However, the penis sometimes does not form correctly and the urethra fails to reach the tip of the penis. The incompletely-developed urethra may form an opening at the under side of the penis (hypospadias) or the upper side of the penis (epispadias).
