Wearing lose-fitting boxers could boost men's sperm count

Wearing lose-fitting boxers could boost men's sperm count

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.

They sought to test the theory that briefs, being more constricting, raise scrotal temperature and have a negative effect on fertility.

"Men could improve their sperm production by easily changing their type of underwear".

Also, the study did not measure actual pregnancy outcomes, so it was unclear whether the differences in sperm count and quality uncovered actually made a bottom-line difference in the desired outcome.

"Men who wore tighter underwear had lower sperm counts than men who wore the most loose underwear", said senior researcher Dr. Jorge Chavarro, an associate professor of medicine with the Harvard T.H. Chan School of Public Health in Boston.

FSH is known to play an important role in male fertility.

The theory is that higher temperatures caused by body-hugging underwear interferes with the testicles' ability to produce sperm, a process called spermatogenesis.

After a rain delay, Cheteshwar Pujara was run out by debutant Ollie Pope and a downpour followed immediately. Such scrambled thinking then did for Pujara after India's No3 set off for a single in Anderson's next over.

Still, Eisenberg said that "if the current study can be consistently reproduced, then I think it's something we should discuss with all patients".

"As a society, traditionally, fertility has been thought of as a female issue". It was published Wednesday in the journal Human Reproduction. 345 men said that they liked boxer shorts, while 311 said that they wore tight underwear. Each provided semen and blood samples and they were asked about the style of underwear they wore most frequently in the preceding three months.

Sperms gets damaged by a tight fitting underwear. For instance, their body mass index, whether they are smokers or not, how much time do they spend in sitting down on a daily basis, or if they enjoyed hot baths or not. When men have trouble conceiving, "we hope that there are other ways that we can intervene that have a little more significant science and data to back them up", she said.

Anything that prevents this cooling is likely to impair both sperm output and quality.

That finding suggests that, in men who wear tighter underwear, decreased sperm production may send a signal to the brain to increase levels of FSH to compensate for the lower sperm production. Other potentially confounding factors that were not taken into consideration included the type of pants worn, and the textile fabric of the underwear.

And while the underwear effect is not "dramatic", Fisch said.

The conviction of the scientists reduced levels of this hormone in men who wear boxers, compared to those who have a more narrow trousers, due to the fact that spermiogenesis occurs normally and is not regulated by the high concentration of hormones, which takes effect at the time of damage of the scrotum is too narrow sheets.
