How menswear is related to sperm production

Men who usually wear boxer underwear have significantly greater sperm counts and quality than those who are wearing tight underwear, according to a new American scientific study, the largest of its kind to date, which evaluated the incidence of the underwear in the quality of the s***n.

The researchers, led by Linda Minguez-Aarcon of the Harvard School of Public Health, who published the publication in Human Reproduction magazine of the European Society of Human Reproduction and Embryology, studied at the Massachusetts General Hospital 656 men aged 32 to 39, of which sperm samples were taken.

The quality of the sperm was associated with every man with the type of lingerie he used to wear. It was found that nearly half of the women who wore systematically “boxers”, which better testicles, had an average 25% higher sperm counts (sperm counts per milliliter of sperm) and 17% more sperm counts (per ejaculate). Also their sperm had a 33% greater mobility (something important for the ability to fertilize the egg).

Scientists believe that the best conditions for sperm production in the testis are the latter to have a temperature of three to four degrees lower than the average temperature of 37 degrees Celsius. But the tighter the men’s underwear, which necessarily tightens the male genitals near the body, increases the temperature, especially when a man exercises or does some physical work in the summer.

On the other hand, the researchers pointed out that, despite the differences in the amount of sperm, it remains within the normal range and the men wearing a “brief”, so it is unlikely that a man can not catch a child for this reason alone , if there are no other causes of infertility. It will just be a little more difficult …

“Our findings show that men can make a relatively easy change when deciding with their partner to make a child,” the investigator said.

“If I was going to start trying to make a kid, I would go buy some ‘boxers’ about three months before I started the effort,” according to the Reuters agency, researcher Dr Jorge Chevrova of Harvard three months to mature sperm after their creation).

For couples who have difficulty catching a child, in almost a third of cases the problem lies exclusively with the man, and in half cases he is also responsible.
