The apocrine glands of the pubis were studied to find out why this area lacks the characteristic body odor of the axilla. The glands were found to be anatomically perfect and physiologically functionless. They do not secrete apocrine sweat. This is considered to be further evidence for the phylogenetic decline of these structures among the higher primates.
