Men with low-pitched voices have an advantage in attracting women, even though women know they're not likely to stick around for long, reveals a new study.
Researchers at McMaster University have found that women were more attracted to men with masculine voices, at least for short-term relationships.
Those men were also seen as more likely to cheat and unsuitable for a longer relationship, such as marriage.
The study offers insight into the evolution of the human voice and how we choose our mates.
"Until now, it's been unclear why women would like the voices of men who might cheat. But we found that the more women thought these men would cheat, the more they were attracted to them for a brief relationship when they are less worried about fidelity," lead author Jillian O'Connor said.
For the study, 87 women listened to men's voices that were manipulated electronically to sound higher or lower, and then chose who they thought was more likely to cheat on their romantic partner.
Researchers also asked the participants to choose the voice they thought was more attractive for a long-term versus a short-term relationship.
The study is published in the journal Personality and Individual Differences.
