Wear Loose Underwear To Improve Your Sperm Production

Switching to roomier smalls could improve sperm quality a new study suggests

The simultaneous presence of lower sperm counts and higher FSH among men wearing tight-fitting underwear suggests the presence of a compensatory mechanism.

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 also noted that the men who wore boxers had 14 percent lower levels of follicle stimulating hormone, compared with men who didn't. Their sperm were 33 percent more motile.

The study included men who visited the Massachusetts General Hospital for fertility problems.

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.

Multiple fatalities confirmed after shooting incident in Canada
The Winnipeg native, who lives immediately off Brookside, said residents have been advised to stay inside with their doors locked. Last month, a gunman walked down a busy Toronto street, killing two people and wounding 13 before turning his gun on himself.

There have been several studies of late that show that there is a steady decline in sperm counts.

Men were asked to recall what underwear they prefer rather than actually being observed, and all of the men were seeking fertility treatment - so the findings might be have been different if other men had been involved in the test.

It adds to evidence that temperature is vital to sperm production.

"These results point to a relatively easy change that men can make when they and their partners are seeking to become pregnant", Lidia Mínguez-Alarcón, the study's lead author and a researcher at the Harvard T.H. Chan School of Public Health, said in a press release.

"It is very important to recognize that the study does not prove a causal relationship between briefs and infertility, but rather an association between briefs and a lower, though still normal, sperm count that may or may not be a cause of infertility", she said. The study was published this week in the latest issue of the journal Human Reproduction. Higher levels in men who didn't wear boxers could be evidence of the body trying to compensate for the challenge to sperm production wrought by tight underwear, Chavarro 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.
