Where does a man's body odor come from?

Men, like women, have a masculine smell that highlights their masculine characteristics. Medical experts have used a special term to describe it, called body odor. Do you know how masculine smell comes from?

Men's body odor is composed of sweat and sex. Sweat comes from the secretions of sweat glands on the body surface. The secretions of sweat glands have no smell. It is only after contacting the skin and "brewing" by bacteria that the smell comes out. The so-called sweat smell contains butyrate, the main odor substance. Once the skin hygiene is poor, bacteria feed on the oil secreted by the skin. As the oil decomposes, the smell will become unpleasant, and the sweat smell will become sweat odor. In summer, mosquitoes chase people and police dogs use their sense of smell to track down fugitives. These are all due to the influence of sweat.

Sexual fragrance is different. The substance that produces this kind of scent is due to the external hormones secreted by the human body. These external hormones are "brewed" by the exocrine glands in the armpits, head, face, chest and genitals, and are also called pheromones. American scientists have separated 11 types of pheromones from human skin cells. These mysterious substances invisibly affect people's basic behaviors, such as mutual attraction between the sexes. At the same time, everyone has their own unique pheromones, just like everyone has their own unique fingerprints.

In addition, substances released by the human body during metabolism can also produce certain smells. According to experts, there are more than 900 kinds of smells, including 149 kinds emitted from breathing gas, 196 kinds from feces, 151 kinds from sweat, and as many as 271 kinds emitted through the skin. It is these smell substances that mix to form the masculine or feminine smell.
