secrete thicker sweat in hair-rich areas, causing body odor
Apocrine glands are a type of sweat gland found primarily in areas with abundant hair follicles, such as the armpits and groin. Unlike the more common eccrine sweat glands, apocrine glands secrete a thicker, milky fluid that, when broken down by bacteria on the skin, can produce body odor. These glands become active during puberty and are influenced by hormonal changes.
