"witching underwear is hardly a risky thing to do," said Pacey, "so buying some looser pants might be good advice for would-be fathers. "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," he said.īut in the meantime, prospective dads – or men who simply want to look after the health of their sperm – have nothing to lose by adopting more flexible garb (or even going without entirely), knowing that in doing so, they may well be protecting their power to procreate. "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."īeyond merely analysing sperm quality, however, future research would offer even more valuable insight if it focused on quantifying the effects of a man's underwear choice. "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," said Allan Pacey, a male fertility expert at Sheffield University in the UK, who was not involved with the study. Although the sample size in the study was relatively small, it's further evidence that adopting a more liberal approach when it comes to undergarments could pose considerable health benefits for men's fertility. In fact, an all nighter hurts your ability to think, reason, and understand to the same degree as if you were taking your test drunk. Sleeping poorly (or not at all) leads to worse test results and poorer ability to learn new things. The researchers found that those who slept naked and wore loose-fitting boxers during the day experienced 25 percent less DNA fragmentation than those who opted for tight underwear like briefs. Should I sleep or study Scores of studies conclude that students really do better when they sleep. Not surprisingly, consolidated sleep is more beneficial than incremental sleep. Winter says, 'Seven to nine hours is recommended for college students,' but stresses that everyone is different.
The study tracked 500 men over the course of a year, taking note of the underwear choices they made and the quality of their sperm. After you've recovered from your Night Of No Sleep, keep an eye on your overall sleep habits.
"Reducing exposure for bed decreases DNA fragmentation better semen quality parameters are observed in men wearing boxers during the day and none to bed." "Among men in the general population attempting pregnancy, type of underwear worn during the day and to bed is associated with semen quality," said lead researcher Katherine Sapra of the US National Institute of Child Health and Human Development. According to a recent study, men who wore boxer shorts during the day and nothing to bed had significantly lower levels of damaged DNA in their sperm compared to those who wore tight underpants during the day and at night.
