'''Hypospadias''' is a common variation in fetal development of the [[penis]] in which the [[urethra]] does not open from its usual location in the head of the penis. It is the second-most common birth abnormality of the male reproductive system, affecting about one of every 250 males at birth.<ref name="Snodgrass">{{REFbook | '''Hypospadias''' is a common variation in fetal development of the [[penis]] in which the [[urethra]] does not open from its usual location in the head of the [[penis]].
