Sweat makes women 'irresistible' to men

Scientists have claimed that the secrets of attraction are hidden in the immune system genes that women inherit from their parents and clues to this are contained in her sweat or appearance, the ‘Daily Mail’ reported.

They have based their findings on an analysis of the DNA of 150 students from the University of Western Australia. The subjects, including would-be doctors and engineers, filled in detailed questionnaire about their love lives.

Their DNA was scrutinised for variation in genes known to influence the immune system. The more diverse these genes, the stronger a person’s defence against disease, the findings have revealed.

The results of the genetic tests were then matched up with the survey answers. This showed that the women with the most varied major histocompatibility (MHC) genes, had the most sexual partners.

However, the scientists can’t be certain why a woman’s immune system affects her success with men.  They aren’t clear whether her genes make her irresistible to the opposite sex — or whether she finds them irresistible.

“It is possible that MHCdiverse women have more sexual partners because they actively seek more partners, rather than because males prefer diverse partners,” the scientists said.

A third possibility is that women with strong immune systems are simply more choosy about who they want to settle down with. “None of these explanations are mutually exclusive and, regardless of the underlying mechanism, the effect of MHC diversity is intriguing and deserves further investigation,” the scientists said.
