The glans penis is the smooth bulbous end of the penile shaft. The urethra, which is the small tube that allows urine and semen to exit the body, is located at the tip of the glans penis. When a man is born, the glans penis is covered by a retractable piece of tissue know as the foreskin. Many men, however, have this piece of skin removed, usually at birth, leaving the glans penis exposed.
Oftentimes, the term glans penis is simply shortened to the glans.
