US-Study Finds a Correlation in Those Who Sleep Naked and Those with Increased Fertility
Tight Underwear Impairs Sperm Quality
This study from the U. Its findings showed that underwear that is too tight can affect sperm quality and reduce the likelihood of reproductive success. To arrive at these conclusions, the team of researchers followed men for 12 months, tracking their choice of underwear during the day and at night and recording their sperm quality data. They discovered that those who wore boxers during the day and slept in the nude had a 25 per cent lower risk of DNA fragmentation in their sperm, which can affect sperm quality, compared to men who usually wore tight underwear during the day and night. The study suggests that men who want to have the best chance of conceiving should take this into account, although it also mentioned that additional research is required. Previous studies have shown that heat exposure and tight underwear had a negative impact on fertility by destroying part of the sperm cells. It showed that sperm count had decreased by 30 per cent in France and the number of spermatozoa was falling by 2 per cent each year. Sperm morphology was also increasingly atypical. In the U.
