[8] Staphylococcus hominis is also known for producing thioalcohol compounds that contribute to odors. [9] These smaller molecules smell, and give body odor its characteristic aroma. [10]
Past research has highlighted the importance of a male's scent to females, such that smell was rated significantly more important for women than men. Furthermore, smell and body odour were rated as the most important physical factor for females, compared to looks for males. [60] Further studies have aimed to understand these sex differences.

Male olfactory ability of canines is superior to that of females because historically it was their duty to find mates and mark territory. [ 1 ]

[2] Odorous socks are a strong attractant for some animals, including dogs and mosquitos.
