Are you trying to have a child? Gentlemen, it’s time to take your clothes off … to improve your chances of design. Researchers from Stanford University (United States) and the National Institute of Child Health and Human Development provide a new argument in favor of nocturnal nudity : improving the quality of sperm. These scientists presented their research during the annual colloquium of theAmerican Society for Reproductive Medicine, in Baltimore (United States).
DNA damage in sperm
To carry out this study, the researchers followed 500 men for a year. The latter had to account for the nature of the underwear worn, day and night. In parallel, the quality of their sperm, and therefore their fertility, was assessed. The result is clear: men who wore loose underwear and slept naked at night had sperm in better shape than those who wore tight underwear day and night. The latter’s sperm have 25% more lesions in their DNA, which affects their viability and can even increase the risk of premature birth for future babies.
Lower the temperature of the testicles
The responsible for this lower sperm quality: heat. “It has long been known that men who increase their testicular temperature, either by direct exposure to heat or by wearing tight underwear, have low-quality semen compared to men who have larger testicles. fresh“confided to Daily Mail Professor Allan Pacey, specialist in andrology, in reaction to this study. It is for this reason that thanks to the wearing of the kilt which keeps the testicles cool, Scots break European fertility records.
To increase the quality of their sperm and therefore their fertility, men should therefore prefer loose underwear during the day and put on their Adam costume at night.
