Apocrine

Apocrine glands are special sweat glands in your body that produce sweat that smells. These glands are found in your armpits, around your nipples, and in your groin area.

When you exercise or feel hot, your apocrine glands produce sweat to cool down your body. But unlike the sweat that comes from other parts of your body, the sweat that comes out of your apocrine glands contains more protein and fats. These substances mix with the bacteria on your skin, which causes an odor. That's why your armpits smell after you've been sweating.

Apocrine glands also play a role in pheromones, which are chemicals that give off subtle scents that can attract or repel people. These pheromones can be found in the sweat produced by your apocrine glands in your armpits, which is why some people wear deodorant or perfume to mask their natural scent.

In summary, apocrine glands are sweat glands in your body that produce sweat in areas such as your armpits, which can smell due to the combination of proteins and fats with bacteria. They can also produce pheromones, which can affect how people perceive your scent.
