A new study by China’s Southwest University reveals that men with deep voices are more likely to cheat on their partners because they have higher levels of testosterone. Researchers had a group of men read a list of words before playing their recordings for women. The women rated the men on a series of factors including fidelity.
Researchers say, ”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.”
