A new study from the National Institute of Child Health and Human Development has revealed one simple factor that could be affecting your man’s health – whether or not he sleeps naked.
Going to bed naked
The research, which took into account data from 500 men across a 10 month period, found a direct correlation between the type of underwear worn in bed, and sperm quality and function – a factor which could potentially affect fertility. Ultimately, men who chose loose-fitting boxers during the day and wore nothing at night had 25 percent less DNA fragmentation in their sperm compared to the chaps who were wearing tight-fitting pants 24/7.

Better sperm quality
‘Among men in the general population attempting pregnancy, the type of underwear worn during the day and to bed is associated with semen quality,’ the lead author of the study explained. ‘Reducing exposure for bed decreases DNA fragmentation, and better quality parameters are observed in men wearing boxers during the day and none in bed.’
Heat affecting sperm quality
According to new research, men who sleep naked are likely to have improved sperm quality and function compared with those who wear underwear to bed. Leading fertility expert Allan Pacey, commented on the findings: ‘We have known for some time that men who increase the temperature of their testicles, either through the heat exposure at work or by wearing tight underwear, have poorer semen quality compared to men whose testicles are cooler.’
