These are only found in the axillae, breast, and pubic and perineal regions. They are similar to apocrine sweat glands, but open out onto the upper regions of hair follicles, like sebacous glands. They only secrete after puberty. They produce a cloudy secretion, which starts to smell if bacteria react with it.
