A recent study by Harvard researchers suggests that men who often wear loose-fitting boxers have significantly higher sperm concentrations and total sperm count than their brief-wearing brethren.

A researcher at the Harvard T.H. Chan School of Public Health and the study’s lead author said in a press release, “These results point to a relatively easy change that men can make when they and their partners are seeking to become pregnant.” Well, if one is wondering how does the type of underwear affect sperm concentration then here is the answer. To understand this, the researchers first collected semen samples from 656 men between the ages of 32 and 39 and asked them what they preferred more, boxers or briefs. 53% participants reported mostly wearing boxers. It was found that these men had 25% higher sperm concentration than the men who mostly wore tighter-fitting underwear and their total sperm count was 17% higher.

That is not the only benefit for people who wear boxers or any loose-fitting underwear, these men also have a higher percentage of what is known as motile sperm. According to the study, these sperms are more adept at moving through the female reproductive system and fertilizing an egg. Also Read - Commonwealth Games 2018: Indian Boxers Assure More Medals
The researchers also collected blood samples from around 300 participants and found that men who wore boxers had 14% lower levels of a hormone called FSH than men who wore tight underwears. FSH is a hormone that is known to play a role in male fertility.
Jorge Chavarro, one of the study’s authors and an associate professor of nutrition and epidemiology at Harvard, said in a statement, “Beyond providing additional evidence that underwear choices may impact fertility, our study provides evidence, for the first time, that a seemingly random lifestyle choice could have profound impacts on hormone production in men at both the level of the testis and the brain”.
