Handsome men have the best sperm, a new study reveals. The researchers showed that men with the healthiest, fastest sperm were rated as the most facially attractive by women.
The characteristics of a person’s face have long been regarded as an indicator of health. But this is the first direct evidence to suggest a man’s reproductive quality correlates with his facial characteristics, say the authors.
Maria Sancho-Navarro, a team member at the University of Valencia, Spain, said that symmetrical faces were rated as more attractive by the women. And other studies have shown that people with more symmetrical features are less likely to suffer ill health.
The researcher team examined 66 male students from Valencia. They showed frontal and side photos of the men’s faces to 66 women, who rated their attractiveness. The men’s semen quality was measured according to World Health Organization guidelines.
