That’s low! Men with deep voices are more likely to cheat on their partners due to higher levels of testosterone, study claims
- Student volunteers recorded certain words and completed a personality study
- Researchers found a link between a deep voice and a higher chance of cheating
- This is due in part to higher levels of testosterone in men with deeper voices
- The team say there was no link between voice pitch and cheating in women
Men with deep voices are more likely to attract a partner, but are also more likely to cheat on their partner – and it is due to high levels of testosterone, study finds.
Researchers from China‘s Southwest University recorded the voices of 88 men and 128 women then had them fill out a form to assess their attitude towards infidelity.
Women are often attracted to men with low, rich voices because they are associated with high testosterone levels which, in evolutionary terms, suggests the speaker will be a good mate for producing healthy children, according to the Chinese team.
However, men with higher levels of testosterone are also more likely to have a lax attitude to infidelity, care less about their relationship and eventually cheat.
The same was not true of women, with no noticeable difference in attitudes to fidelity whether they had high or low pitched voices.
Researchers didn’t name any specific people in their study, but a number of male celebrities with deeper voices such as Frank Sinatra, Arnold Schwarzenegger, Brad Pitt and Orson Welles have had high profile affairs

All of the volunteers were young students aged 18-25, heterosexual, non-smokers and in good health when they had their voices recorded.
After being asked to read out a list of words, their voice recordings were analysed for the various kinds of frequency and pitch that are influenced by a number of factors including the shape of the mouth, their larynx and levels of testosterone.
They then took a psychological test with questions on their attitudes to fidelity and relationships such as how they felt about cheating on a partner.
Men with deeper voices were less committed to their relationships and more likely to be unfaithful, they reported in the journal Personality and Individual Differences.

This suggests that testosterone is the key factor in fidelity, said the researchers.
‘Testosterone and the characteristics dependent on testosterone can be reliable indicators of quality-dependent conditions or behaviours,’ they wrote.
‘Men with higher testosterone levels, and hence, lower voices, may have more infidelity behaviours or less commitment to their romantic relationship.’
Having a sexy low voice could be part of the problem as it ‘makes them more attractive to women which increases their opportunity for sexual encounters outside of their own romantic relationship,’ the team added.
It also increases their chances of ‘obtaining more or higher quality partners’.
Men with higher levels of testosterone – as seen through a deeper voice – are more likely to have a lax attitude to infidelity, care less about their relationship and eventually cheat
Men with the deepest voices were ‘more likely to engage in infidelity, and reported lower relationship commitment’ compared to those with higher pitch and frequency.
It wasn’t just the men with deep voices reporting a more relaxed attitude to fidelity – women also perceive men with deeper voices to be more likely to be unfaithful.
People with lower levels of testosterone may be ‘better at reading other people’s emotions’ which leads to enhanced relationship commitment levels, authors say.
The study was conducted with young adults from the university and researchers admitted that further studies of older men and women were needed to see if this was true across other age ranges and in longer-term relationships.
The findings were reported in the journal Personality and Individual Differences.
