To become a dad without stress, always wear boxers, not skin-tight briefs

The abstract for the study concludes: "Men who reported most frequently wearing boxers had higher sperm concentration and total count, and lower FSH levels, compared to men who did not".

Earlier studies had indicated that tighter underwear, resulting in elevated scrotal temperatures, may contribute to poor sperm quality, but the results had been inconsistent.

In the study led by Dr Lidia Minguez-Alarcón, researchers recruited 656 male partners of couples who were undergoing infertility treatment at the Massachusetts General Hospital between 2000 and 2017.

Researchers at Havard University found that men who wore boxers had a 25 per cent higher sperm concentration and a 17 per cent greater sperm count than men wearing different forms of underwear, reports New Scientist. Could modern living really be threatening the survival of our species?

When in comes to male fertility, it seems the old "brief versus boxers" debate has finally been settled.

In addition, more sperm were correctly shaped.

According to Chavarro, not all men need to change their underwear overnight but those who are having trouble conceiving should consider boxer shorts over briefs.

Alas for Claude Puel's men, they wouldn't nab an equaliser, with United getting their campaign underway with all three points. It's not a problem, it's the win that is most important'.

Some styles of underpants, such as jockey shorts or briefs, bring the scrotum nearer to the body, causing the testicles to warm up, while others, such as boxer shorts, are looser and cooler. The increased FSH may be compensatory mechanism by the body to counter the effects of the tighter underwear, the researchers said. Each provided a semen and blood sample, and answered a questionnaire that asked about the type of underwear they most often wore during the preceding three months.

Men who wore boxers also had higher percentages of motile sperm or sperm that are capable of moving through the female reproductive system and fertilizing an egg. The authors feel that more research is required in this field covering more aspects like the fabric of the underwear, the different types of trousers wore etc.

Those with looser-fitting underwear produced up to a third more swimming sperm than those who preferred budgie-smuggler type briefs.

A "man's sperm counts can vary tremendously week to week", said Dr. Sarah Vij, a urologist at the Cleveland Clinic who was not involved with the study.

Other lifestyle activities of these men were also seen.

Other factors that might affect scrotal heat - such as the type of pants worn and underwear fabric - could also affect the results. "I generally counsel men that they can choose the type of underwear that is most comfortable", Eisenberg told "But if they do feel warm or constricted, then another type may make sense", he added.
