What is the main function of the apocrine glands?

The main function of the apocrine glands is to produce a thicker secretion that can develop an odor. These glands are primarily located in areas such as the armpits and groin, where they are associated with hair follicles. The secretions from apocrine glands are rich in proteins and fatty acids, which provide a suitable environment for bacterial growth. When bacteria metabolize these secretions, they produce byproducts that can lead to body odor. This distinguishes apocrine glands from other sweat glands that mainly function in thermoregulation and moisture control, which do not possess the same odor-producing properties.
