Are Tighty-Whities Bad for a Man’s Sperm Count?

  • Men who wear boxer shorts have a higher sperm count than men who wear briefs

Blood samples collected from 304 of the participants also showed that men who wore boxers had 14 percent lower levels of a substance called follicle stimulating hormone, or FSH.

The researchers said this likely shows FSH levels increase when it needs to compensate for testicular damage indicated by increasing scrotal temperatures, and decreasing sperm counts and concentration.

The study, conducted from 2000 to 2017, looked at men who came to Massachusetts General Hospital as part of a couple with fertility problems.

In a study of 656 men, by researchers at Harvard TH Chan School of Public Health, in the U.S., boxer short wearers had a 25% higher sperm concentration than men in tight-fitting underwear.

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.

Researchers led by Lidia Minguez-Alarcon of the Harvard T.H. Chan School of Public Health in Boston examined 656 men of normal weight, aged 18 to 56, whose partners were seeking infertility treatment at a clinic. Could modern living really be threatening the survival of our species? Along with hot Jacuzzis, tight briefs have been implicated in lowered fertility in men for a long time.

The explanation behind this process seems to be that when sperms gets damaged by a tight fitting underwear, the brain responds by producing more FSH to try and rectify the situation.

Firty-three percent of the men said they usually wore boxers.

Among them, 53 percent wore boxer shorts.

Pogba penalty sets United on way to win over Leicester
In May, the world-class Spanish goalkeeper won Manchester United's Player of the Year award for the fourth time in five seasons. It's not a problem, it's the win that is most important'.

Men fond of wearing tight underwear who are now trying to conceive a child might want to think again following a new study.

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.

A new United States study has found that men who wear loose-fitting boxers have a significantly higher sperm count than those who wear other types of underwear. The authors feel that more research is required in this field covering more aspects like the fabric of the underwear, the different types of trousers wore etc.

They should probably choose boxers next time.

Dr. Jorge Chavarro, lead author of the study and associate professor of nutrition and epidemiology at Harvard, told NBC News their study confirms previous smaller-scale studies.

According to experts, the reasons for this trend are mostly external: it can be both environmental factors (e.g., poor environment), and peculiarities of lifestyle (reduced physical activity, Smoking or obesity).

The type of underwear the men wore was self-reported and not verified by researchers.

A number of small-scale studies previously have linked tighter underwear to lower sperm counts, Chavarro said.
