Men sleeping in the nude is something that might be frowned upon in some prudish quarters, but those who practice it on a regular basis can now point to a very valid reason for doing so.
Science.
That’s right, according to a study from the National Institute of Child Health and Human Development in Maryland and Stanford University in the US, men who wear boxers during the day and sleep naked at night do 25% less damage to their sperm than those who wear briefs.
The study, referenced in the Daily Telegraph, tracked 500 men and monitored their choice of underwear and sperm quality over a 12-month period and found that men who slept in the nude are more likely to make their partner pregnant.
Commenting on the results of the study, Allan Pacey, leading fertility expert and Professor of Andrology at the University of Sheffield, said: “We have known for some time that men who increase the temperature of their testicles, either through the heat exposure at work or by wearing tight underwear, have poorer semen quality compared to men whose testicles are cooler.
“What has never adequately been shown is whether men can improve things by changing the choice of their underwear, but this study – although quite small – goes some way to suggest that is true.
“What we really need to see is whether switching to looser underwear makes their partners get pregnant more often or quicker than they would have done had the men continued to wear tight underwear.
“Having said that, switching underwear is hardly a risky thing to do, so buying some looser pants might be good advice for would be fathers.”
There you have it gents, let them roam wild and free.
