Overview of the 1995 sweaty T-shirt study: women smelled T-shirts worn by different men, for several days, and picked the ones they were most sexually attracted to; the men and women were then DNA typed, and the attraction patterns indicated that women tended to choose the scents of the men they were most MHC complex dissimilar to.Swiss biologist Claus Wedekind, based on earlier animal studies, which found that people are most attracted to the scent of someone of the opposite sex that has the most dissimilar immune system to their own.That led to work on laboratory mice and rats that established that the animals preferred mates that were different in their MHC genes.Laboratory studies soon proved Thomas right in the case of mice.Three of the seven boxes contained T-shirts from men harboring MHC similar to the woman's own; three contained T-shirts from MHC-dissimilar men; and one contained an unworn T-shirt as a control.

Wedekind put each shirt in a plastic-lined cardboard box with a sniffing hole on top. Each was scheduled for the experiment at the midpoint of her menstrual cycle, when women's noses are reputedly the keenest, and each was presented with a different set of seven boxes. The results of the sweaty T-shirt study are used by the science-based pair matching site Scientic to match people. American anthropologist Helen Fisher calls the sweaty T-shirt study "one of the most important modern scientific studies".Inbred mice, who were alike in all genes but MHC, could detect a difference in the scent of a relative that harbored an ever-so-slightly different MHC gene.Moreover, their odor preferences were not innate but learned.In this study, Wedekind had a group of female college students smell T-shirts that had been worn by male students for three nights, without deodorant, cologne or scented soaps.
