Loose underwear may be good for sperm production

He cautioned that there is no definitive proof that switching underwear style would make any difference because there may be other factors behind the link between wearing boxers and increased sperm count. Well, if one is wondering how does the type of underwear affect sperm concentration then here is the answer.

So if you and your partner are trying to have a baby, boxers might be a good choice.

At least, they've determined which option is better if having a child is an immediate goal.

According to new research led by Harvard T.H. Chan School of Public Health, men who most frequently wore boxers had significantly higher sperm concentrations and total sperm counts when compared with men who did not usually wear boxers. To understand this, the researchers first collected semen samples from 656 men between the ages of 32 and 39 and asked them what they preferred more, boxers or briefs.

Tens of thousands of Druze and their supporters rallied in central Tel Aviv on Saturday to protest against the legislation. The wave of criticism piles pressure on Prime Minister Benjamin Netanyahu, who is already beset by corruption allegations.

The full findings are present in the journal- Human Reproduction.

But if that isn't enough to put men off of wearing them in favour of boxers, this new study just might.

That's not the only advantage to looser fitting undergarments: Men who mostly wore boxers also had a higher percentage of what's known as motile sperm.

Previous research has linked increased scrotal temperatures to adverse testicular function, so the team of experts set out to examine whether a man's type of underwear had any effect. "Though the physiological mechanisms behind this pattern remain mysterious, the authors also discovered that men who wore briefs, "jockeys" (tight but long undies), or 'bikinis" (tight and very short undies) had lower blood levels of follicle-stimulating hormone (FSH) - a chemical messenger involved in spermatogenesis that is produced in the brain's pituitary gland. In that, the decreased sperm production among men in tighter underwear signals the brain to boost production of hormones that stimulate the activity of the gonads to try to increase sperm production.
