L'odeur s'explique par le fait que les asiatiques ont moins de glandes sudoripares (apocrine sweat glands en anglais) qui produisent la sueur.

East Asians have fewer such glands than Europeans and people of Sub-Saharan African descent, which decreases their susceptibility to body odor. Individuals of African ancestry have the largest and most active apocrine glands. Racial differences also exist in the cerumen glands: apocrine sweat glands which produce earwax. East Asians have predominantly dry earwax, as opposed to sticky; the gene encoding for this is strongly linked to reduced body odor, whereas those with wet, sticky earwax (Europeans and Africans) are prone to more body odor.
