Many boys who love to wear boxers feel that the loose design of boxers makes them casual to wear, more comfortable and cool than briefs, and more comfortable to move. Some boys even wear them as shorts in informal situations, such as bedrooms, dormitories or the seaside.
According to the research report, the loose and breathable characteristics of boxers are more conducive to reproductive health and fertility. The principle is that testicles need a low temperature environment when making sperm, and boxers can let air circulate to achieve this condition; On the other hand, briefs increase the lower body temperature by pressing the genitals. However, this view has also been questioned. Most of the objections are that wearing briefs or boxers will not significantly lower the body temperature of the lower body, so the influence of underwear types on sperm can be ignored.
