Ugly men more fertile than handsome ones?
Want to get pregnant? Look for an ugly man.
Scientists have found that attractive men produce less sperm during sex, reported Australian news site, news.com.au.
Apparently, good-looking men are programmed to hold back their sperm in each sexual encounter so that they can increase their chances of impregnating more females.
However, as unattractive men realise that they are less lucky in bed, they will give it their best shot when they manage to bed a female, continued the report.
The findings from this study - which analysed mathematically modelled male ejaculation strategies - by University of Oxford and University College London (UCL) researchers will be published in an upcoming issue of American Naturalist.
Previous animal studies have shown similar mating patterns in chickens and fish.
Said UCL researcher Sam Tazzyman: "Human attractiveness is complicated and influenced by a number of factors including cultural preferences.
"Nonetheless, ejaculate size and sperm quality are likely to have been moulded by similar forces, like attractiveness and the number of sexual partners, that are important in other species."
What Singapore doctors think
Singapore doctors, however, had a different take on the study.
Typically, sperm has a "freshness period" of about two to three weeks. When this time frame is passed, sperm will meet with a decrease in quality and eventually die, said Dr Peter Lim.
Dr Lim is a senior consultant and medical director of the andrology, urology and continence centre at Gleneagles Hospital.
He also told Shin Min Daily News that sperm in young males will be released via nocturnal emission if they do not engage in intercourse.
Older men's body systems are structured in such a way that their bodies would automatically eliminate sperm, he said.
With the body's way of eliminating sperm, the "active" ejaculate from less attractive men who sleep around less may not necessarily be of a higher quality or quantity.
Dr Yang Zhi Keng from the Singapore Men's Health Clinic said that the results from the study were interesting, but they may not be correct.
"Although frequent intercourse does affect sperm quality and quantity, not every good-looking male will be sleeping around with multiple partners.
"So the study can't summarise behaviour just like that," he said.
