MICROANATOMY

Detailed explanation-1: -Apocrine sweat glands start to function at puberty under the stimulation of sex hormones. They are associated with hair follicles in the groin and axillary region. The viscous, protein-rich product is initially odorless but may develop an odor after exposure to bacteria.

Detailed explanation-2: -Apocrine glands produce viscous, lipid-rich sweat, which is also comprised of proteins, sugars, and ammonia [21, 23]. The function of apocrine glands in many species is generally regarded as scent glands involved in production of pheromones (body odor), although this social/sexual function is rudimentary in humans.

Detailed explanation-3: -In humans, apocrine sweat glands are found only in certain locations of the body: the axillae (armpits), areola and nipples of the breast, ear canal, eyelids, wings of the nostril, perineal region, and some parts of the external genitalia.

Detailed explanation-4: -Apocrine, found in the armpits and perianal region, have ducts opening onto the skin surface. They are presumed to have developed in puberty from the eccrine glands, and can comprise up to 50% of all axillary glands.
