Single Men Are Smellier Than Those Who Have a Partner, Study Claims (And It May Help Signal Their Relationship Status to Women)
By Cheyenne MacDonald, Feb 2019
Single men tend to have stronger body odor than their coupled counterparts, according to a new study.
And, it may actually work in their favor.
Building off of prior research that found single men have higher testosterone levels, researchers recruited men to work up a sweat, and had women then sniff the armpit of their T-shirts to see if there were detectable differences in smell.
Not only did single men have a stronger body odor, but the study found women also rated their faces as more masculine than the men who were in relationships.
…‘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,’ the researchers write in the paper.
In addition to testosterone levels, the researchers say non-hormonal lifestyle differences likely come into play as well.
The study isn’t the first to examine the possible link between testosterone levels and body odor.
A separate study published in 2013 found that women tend to be more attracted to men who have higher testosterone levels – but only when they’re ovulating.
