The external reproductive organ of the male. The penis is made up of two parts, the shaft and the glans. The glans is the tip of the penis, while the shaft is the main part of the penis and contains the tube (urethra) that drains the bladder. All boys are born with a foreskin, or a covering over the tip of the penis. Some boys are circumcised, which means that this covering of skin is removed. Other boys are not circumcised and may have skin that covers the tip of the penis. If circumcision is not done the skin must be pulled back for proper cleaning.
