The lower voice, the more likely that the man reduced fertility due to the low concentration of sperm, Australian psychologists argue Lee Simmons, Marian Peters and Gillian Rhodes. In their study, they were given to listen to recordings of the voices of women 54 men aged 18-34 years, and then asked his players to evaluate their attractiveness. As expected, the most attractive ladies considered owners of the deepest voices. That they were asked to hand over sperm researchers for further analysis.
The audit found that men with low sperm quality voice lower than those of men with a less masculine voices, and here's why. Thick low bass, as scientists have found, indicating elevated levels of the male sex hormone testosterone and its too much concentration reduces the number of active sperm men during ejaculation. Perhaps this is due to the evolution of human nature: a courageous appearance males and so attractive to partners and, therefore, they do not need to have some additional qualities in breeding.
