According to a new study from the University of Oxford and University College London, attractive men produce less sperm during sex than unattractive men.
Australian news website, News.com.au, reports on the research, suggesting that women that want to get pregnant find themselves an ugly man.
Researchers at Oxford believe the reason why attractive men produce less sperm during sex is biological. Attractive men’s biology may be programmed to produce less sperm during each sexual encounter in order to be able to impregnate more women.
Uglier men, on the other hand, may not have as many sexual encounters so when they do have sex they don’t hold back on sperm production.
Sam Tazzyman from University College London said, "The more attractive a male is, the more females will be willing to mate with him, reducing the value of each mating to him. This means it is optimal for him to contribute fewer sperm per mating."
