Most women would swoon over a man with a deep voice. But fear not all you high-pitched squealers: a recent study has found that men with deep voices actually have lower-than-average semen quality. Specifically, the study authors write:
Consistent with previous voice research, women judged lower pitched voices as more masculine and more attractive. However men with lower pitched voices did not have better semen quality. On the contrary, men whose voices were rated as more attractive tended to have lower concentrations of sperm in their ejaculate.
As for why ladies have a thing for deep-voices? According to the Scientific American, a deep voice might be a symbol of sexual and social maturity: men who speak in low tones may be perceived as powerful and established.
