The study, published in the journal Frontiers in Psychology, has found that guys without partners smell "noticeably worse" than men that are married or in a serious relationship.
Researchers from Macquarie University in Australia asked 82 heterosexual women to, well, get in there and sniff the sweaty armpits of a group single and married men between the ages of 18 and 35. Poor hygiene was not a problem with the group.
What they found was that single men produce more testosterone than men in serious relationships, which naturally results in a stronger body odor.
"Previous research indicates human body odor (BO) can signal kinship, sickness and genetic compatibility. Based on research indicating single males have higher testosterone levels than partnered males and that higher testosterone levels are associated with stronger smelling body odor, the current study aimed to determine if, by extension of previous findings, single males’ BO smells stronger than partnered males’ BO," reports the study. "Eighty-two heterosexual women aged 18–35 years rated the BO and faces of six different males also aged 18–35 years.
"Consistent with the hypothesis, single men’s BO smelled stronger than partnered men’s BO and single men’s faces were rated as more masculine than partnered men’s faces."
Researchers said the results can potentially allow females to identify single males with their nose.
