Epispadias is a rare congenital defect affecting the location of the opening of the urethra.

In boys with epispadias, the urethra usually opens on the top or side of the penis, rather than through the tip. Sometimes the urethra is open the entire length of the penis. In girls, the opening is usually between the clitoris and the labia. Sometimes the opening is in the abdomen.

What are intersex disorders?
Someone with an intersex disorder has a mixture of male and female reproductive structures. It is not clear at birth whether the individual is a male or a female.

What is Klinefelter Syndrome?
Klinefelter Syndrome is a genetic disorder in which males have at least one additional X-chromosome. Normally, males have the combination of sex chromosomes XY. But in Klinefelter Syndrome, males have more than one X-chromosome resulting in the combination XXY.

Symptoms of Klinefelter Syndrome vary, although most affected newborn boys appear normal at birth. Many XXY males do not develop the symptoms of Klinefelter, and often live their lives normally. Others, especially those with more than one additional X-chromosome, exhibit more severe disabilities that may affect their physical and developmental abilities and personality.
