In addition to the appearance, the boxer may be the best underwear for men, aiming to become a father.
A new study published in the journal Human Reproduction on Wednesday showed that men in loose tights had higher sperm concentrations than men’s tights. Sperm concentration is the number of sperm per ml of semen and is one of the few standard indicators of male fertility.
However, men who like “bikini”, better known as briefs and other tights, have higher levels of follicle stimulating hormone than men in boxers.
Because this hormone stimulates sperm production, the researchers speculate that these higher levels will stimulate the testicles to work harder when producing sperm, which may be the way the body compensates for reduced sperm concentration.
“The study’s lead author, Lidia Mínguez-Alarcón, a research scientist at Harvard University’s T.H., said: “The choice of underwear to influence sperm production has been the subject of research. “Chen Public Health College. However, this study is the first method to study whether male choice of underwear will affect his testicular function, including reproductive hormones and DNA fragmentation,” she said.
According to data from the American Society for Reproductive Medicine, semen analysis is a microscopic examination of male ejaculation. The parameters in the examination include the amount of semen (the amount of liquid ejaculated by men during high tide), the number of sperm (the total number of sperm in each sample), the sperm concentration (the number of sperm per ml), the sperm motility (the number of sperm moves), and the sperm morphology ( Whether the sperm is the correct size and shape).
“Although the analysis of semen samples is the first step in diagnosing male infertility, it is not certain,” Mínguez-Alarcón said. Despite this, she and her colleagues still use semen analysis and testicular function measurements to understand the possible effects of male underwear choices.
In this study, her recruited men and their partners sought infertility treatment at the Massachusetts General Hospital between 2000 and 2017. Ages ranged from 18 to 56 years old, and each male provided semen and blood samples and responded to a questionnaire about their underwear. .
Of the 656 men, slightly more than half (345) reported that they usually wore shorts. In general, these men tend to be younger, slimmer, and more likely to take a hot bath or step into the jacuzzi instead of wearing tights.
The boxer shorts group has a 25% increase in sperm concentration, a 17% increase in sperm count, a 33% increase in vitality (swimming) sperm, and a 14% lower follicle stimulating hormone level than male researchers in “tight shorts” and other tight shorts. Smoking, physical activity and other conditions that may affect the outcome are taken into account.
However, no significant differences in DNA damage or other reproductive hormones were found between the two underwear groups.
“It may not be possible to generalize our findings to the general population,” Mínguez-Alarcón said. She added that other weaknesses in her research include her and her colleagues lacking information about other lifestyle factors that may affect scrotal fever – such as the type of pants worn and the fabric of the underwear. It is well known that extreme heat can cause a drop in semen production.
