Apocrine sweat glands begin secretions at which life stage?

Explanation:
Apocrine sweat glands start secreting during puberty because their activity is driven by rising androgens in adolescence. Before puberty they’re mostly inactive, even though present, so you don’t see their thicker, protein-rich secretions that later contribute to body odor after bacteria breakdown. These glands are concentrated in hair-bearing areas like the armpits and groin and produce a viscous sweat that isn’t primarily for cooling. In contrast, eccrine glands are active from infancy and handle thermoregulation. So puberty marks the onset of functional apocrine secretion.
