Hypospadias is a birth defect in boys in which the opening of the urethra is not located at the tip of the penis. In boys with hypospadias, the urethra forms abnormally during weeks 8–14 of pregnancy. The abnormal opening can form anywhere from just below the end of the penis to the scrotum. There are different degrees of hypospadias; some can be minor and some more severe.
