(2) Covering the glans ("head") of the penis is a fold of skin called the
prepuce. In many cultures, the prepuce is removed shortly after birth in the procedure
called circumcision. At the base of the glans, there are glands that secrete a lipid-like
material called smegma. Thus, there is a need for continual cleanliness.

muscularity, deep voice, and hair distribution.
