Scientists have warned men against wearing underpants to bed. This is because wearing underpants to bed can make the crotch area too warm.
Men are being urged to go to bed naked as it could boost their chances of becoming a father.
Dr Brian Steixner, director of the Institute for Men’s Health at Jersey Urology Group told The Sun: “Your nether regions need to be just the right temperature in order to optimise sperm production.
“More bacteria makes for a higher likelihood that any chafed or irritated skin down there becomes infected.”
Sleeping naked helps lower the body temperature which increases a man’s sperm production by keeping his scrotum at a specific temperature.
Sleeping naked is also good for couples because skin-to-skin contact releases oxytocin in the brain which strengthens emotional bond.
