Scrotum
The "sac" between a man's legs is called the scrotum. It is what protects and contains the testes. The scrotum also regulates the temperature of the testes. When they are hot, the skin becomes very soft, and there may even be sweating. When the testes are cold, the skin of the scrotum becomes stiff, shrunken, and leathery.
Hair forms in a pouch-like structure below the skin called a hair follicle.

A female manatee's mammary glands (milk glands) and teats are located behind the forelimbs or flippers, one per side. Like cattle and goats, a manatee's milk glands have no storage sacs, so manatee calves suckle frequently at short intervals. Consequently, in absence of a storage sac, expectation of any substantial milk yield would not be possible.
There are typically two testes situated in the scrotum. The scrotum is a sac of skin that houses and protects the testes, which are responsible for producing sperm and hormones.
It is called an ascus.
