Research into the effect of underwear on sperm quality has found that men who opt for airy boxer shorts made much more sperm than those who wore restrictive pairs.

The researchers explained in Human Reproduction how they quizzed men in couples who were seeking fertility treatment about their favourite underwear choices.

The study, called Type of underwear worn and markers of testicular function among men attending a fertility center, involved getting 656 men to give a semen sample, before answering questions about what sort of underwear they wore the most in the last three months.

Men who wore airy boxers had 25% more sperm per millilitre and ejaculated 17% sperm in each ejaculation, as compared to men who wore briefs, smaller trousers or tighter underwear.

It's been suggested that 21st Century man is, reproductively speaking, only half the man his grandfather was.

The levels of follicle-stimulating hormone or FSH was found to be higher among men who wore briefs regularly.

She did have the advantage being born into a super successful reality TV family that laid the groundwork for literally every opportunity she's had. "And I don't know, the whole thing is really... it's like such an awesome experience".

The study was published August 8 in the journal Human Reproduction. They were given the choice of "boxers", "jockeys", "bikinis", "briefs", or "other".

The study strongly also does not prove that there is any connection between tight boxers or underwear and low sperm count.

Men who wear tight underwear could increase their chances of having children by switching to looser fitting boxer shorts, scientists are recommending.

Sperm production is affected by temperature, and needs a cooler environment than in the nearby abdomen.

Dr. Jorge Chavarro, associate professor of nutrition and epidemiology at Harvard, lead author of the study has explained that tight underwear in men such as briefs can raise the scrotal temperatures and this can contribute to a lower sperm count and infertility. "There seems some compensation, but this compensation is not sufficient to bring them back to sperm counts of men who wear looser-fitting underwear".

Guys with tighter-fitting pants also had higher levels of a hormone that encourages sperm production - likely to compensate for all the seed that gets fried in their high-temperature unmentionables, researchers said. From the semen samples the team of researchers looked at total count of sperm, motility of the sperms, morphology or appearance of the sperm and the extent of DNA damage to the sperm.
