The hard truth you’ve known all along has finally been proven…by science.
In a recent U.S study researchers from the Harvard TH Chan School of Public Health found that men who wore boxer shorts had a 25 percent higher sperm count than those in tighter fitting underwear. In other words, go commando and you’ll never shoot blanks again.
The scientific explanation published in the journal Human Reproduction is of course a bit more complicated than that. It relates back to keeping the hormones that affect the sperm count happy. The study which accounted for 656 men found that cooler temperatures around the testicles boosted sperm production.
This is due to the fact that sperm production is most sensitive to temperatures above 34 degrees Celsius (92F). This phenomenon can be seen on warmer days when your testicles hang lower from the body when compared to cooler days when they contract closer to the body.
In the realm of underwear, briefs and jockey shorts hold the scrotum closer to the body which causes the testicles to warm up. Boxer shorts meanwhile accommodate a looser and ‘airier’ fit that’s more conducive to sperm production. So in other words, cheap underwear has nothing to do with it.
The figures from the research reveal a 17 percent increase in total sperm count alongside 33 percent more swimming sperm when comparing boxers to tighter-fitting underwear. Thankfully this finding doesn’t affect sperm shape or DNA quality – it’s simply a numbers game.
“Since men can modify the type of underwear they choose to wear, these results may be useful to improve men’s testicular function,” says the study’s lead researcher, Dr Lidia Minguez-Alarcon.
The surprising results were derived against factors that affect sperm production including a man’s age, body mass index (BMI) and personal habits such as smoking and…we kid you not…hot tub usage.
Be warned though, changing your underwear today won’t warrant a higher sperm count the next day.
The research paper’s author Dr Jorge Chaverro told the BBC that “it takes about three months for an entire population of sperm to change, so plan in advance.”
Well there you have it. Who said free-balling on the daily was a nuisance to society?
