According to new research led by Harvard T.H. Chan School of public health, Men who frequently wear boxers had significantly higher total sperm counts and concentration of sperms when compared to the men who don’t usually wear boxers.
The research were conducted at a Fertility clinic in Massachusetts General Hospital among 656 men who were a part of couples and undergoing fertility treatment.
The findings prove that the certain style’s of underwear may hinder production of sperm.
“These results point to a relatively easy change that men can make when they and their partners are seeking to become pregnant.” Said Lidia Mínguez-Alarcon, a research scientist at Harvard Chan School.
The men who were between the ages of 32 and 39, were included in the survey. The survey included the questions about the style of underwear they wore in the previous three months. Options included boxers, jockeys, bikini, briefs, and other.
Among the study participants, 53% of men usually wear boxers. Analysis of semen samples showed that these men had 25% higher sperm concentrations and 17% higher total sperm counts when compared with men who did not primarily wear boxers.
Beyond that, the blood samples of 304 participants were collected. The testing of those samples showed that the men who wore boxers had 14 percent lower levels of follicle stimulating hormone (FSH) compared with men who didn’t wear boxers.
FSH plays and important role in male fertility and sperm production. The decreased sperm production among men in tighter underwear signals the brain to boost production of hormones that stimulate the activity of the gonads to try to increase sperm production.
The study is published on August 8 in “Human Reproduction”.
