Body odor

There are two types of sweat glands in the human body. One is the exocrine sweat glands that spread throughout the body, and the other is the apocrine sweat glands, which are clustered around the armpits and groin. This sweat gland is secreted. Medical research has shown that the secretions of sweat glands are odorless, and they emit a scent only after they attach to the skin and react to a certain chemical reaction with bacteria. If you leave it alone, bacteria will feed on the secreted oil, and as the oil breaks down, it will emit an unpleasant taste. And because men secrete extra testosterone, they will produce more fat that causes body odor than women, and men sometimes pay less attention to personal hygiene than women, so they will easily produce body odor.
