In the largest study of its kind to date, the researchers found men attending a fertility clinic with looser-fitting boxer shorts had higher sperm concentration, a 17% higher total sperm count and 33% more swimming sperm than men with tighter-fitting underwear.
Previous research has linked increased scrotal temperatures to adverse testicular function, so the team of experts set out to examine whether a man's type of underwear had any effect.
The study included men who visited the Massachusetts General Hospital for fertility problems. 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.
Scientists at the Harvard T H Chan School of Public Health tested 656 men and found that those who wore boxers had 25% more sperm per millilitre and 17% in each ejaculate than those that wore briefs, jockeys or smaller trousers.
"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's been suggested that 21st Century man is, reproductively speaking, only half the man his grandfather was.
Turns out, certain styles of men's underwear may inhibit production of sperm.
Firty-three percent of the men said they usually wore boxers.
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.
Chavarro told New Scientist that, although men who wear tight underwear have a lower sperm count, they generally still have sperm concentrations that fit in the average range. 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.
