the
male scrotum
In
some male mammals
the scrotum is a protuberance of skin
and muscle
containing the testicles.
It is an extension of the abdomen,
and is located between the penis
and anus.
In humans and some other mammals, the base of the scrotum becomes
covered with pubic
hair at puberty.
In common speech, the scrotum is often improperly referred to as the
testicles, which actually refer to organs encased inside the scrotum.
The scrotum is homologous to the labia
majora in females. It becomes tight when sexually aroused.
