Boxer briefs
Boxer briefs (sometimes spelled boxer-briefs or called tight boxers, also known as A-Fronts) are a hybrid type of men's undergarment which are long in the leg, similar to boxer shorts, but tight-fitting like briefs. They emerged as a style in the 1990s and are commonly worn for sports and as every-day underwear.
Possible effect on male fertility[edit]
Some studies have suggested that tight underpants like boxer briefs and high temperature are not optimally conductive for sperm production. The testicles are outside the body for cooling because they operate for sperm production at a slightly lower temperature than the rest of the body, and boxer shorts allow the testicles to operate within the required temperature range. The compression of the genitals in boxer briefs, briefs, thongs, etc. may cause the temperature to rise and sperm production to fall. There is a similar theory regarding testicular cancer risk.[5] Other sources dispute this theory. A study in the October 1998 Journal of Urology, for example, concluded that underwear type is unlikely to have a significant effect on male fertility.[6]
Several pairs of boxer briefs compared with loose boxer shorts.
Rear stitching on these boxer briefs avoids a central seam and outlines the buttocks.
