MEN with deep voices are luckier in love, according to a study.
Research found that having a lower pitched lilt was linked to “more unrestricted sexual behaviour”.
It is likely a sign of high testosterone levels, which make men more attractive to women, scientists said.
A study by the University of the Republic in Uruguay used voice recordings and questionnaires from 101 men and 147 women.
There was a “significant” link between blokes’ sex lives and the frequency and loudness of their speech.
It is a stroke of luck for those with tones like Barry White or a boom like Brian Blessed.
Dr Alvaro Mailhos said: “Our findings show a trend where men with lower-pitched voices exhibit a more unrestricted sexual behaviour.
“This is in line with previous studies which have shown that lower frequency male speech is related to higher scores on the sociosexuality scale, and that males with lower-pitched voices have higher reproductive success and more children born to them.”
The sexuality scale asked people about their number of partners in the past year, one-night stands, having multiple partners at once and how often they think about making love.
Those with deeper voices had higher scores on average, showing that they had sex with more people and felt stronger desires.
The study, in the journal Frontiers in Psychology, found no significant differences in the tone of a woman’s voice and her sex life.
Dr Mailhos said the hormone testosterone may be behind the link in men.
High testosterone was attractive to our female ancestors because it signalled greater strength and aggression, making men better able to protect their families.
Dr Mailhos added: “Males with lower voice frequency may have a higher number of sexual partners by deterring romantic rivals or by attracting romantic partners.
“It is more difficult to think of an adaptive function of higher sexual desire.
“We think that probably relies on the simple fact that vocal cords and the brain structures involved in sexual motivation are under the effect of the same hormones.”
Past studies have found women rate deep-voiced men as more attractive – but also that they are more likely to cheat.
