SpletThe sweat only attains its characteristic odor upon being degraded by bacteria, which releases volatile odor molecules. [23] More bacteria (especially corynebacteria) leads to stronger odor. The presence of axillary hair also makes the odor even more pungent, as secretions, debris, keratin, and bacteria accumulate on the hairs. [15]
