3. Men should not wear briefs.
Men's underwear can be divided into boxers and briefs. The testicles of many victims packed in briefs ranked first. Tightly bandaging the private parts of the briefs fastens the scrotum and keeps him close to the abdomen, which will greatly weaken the temperature regulation function of the testicles, increase the ambient temperature around the testicles and hinder the spermatogenesis of the testicles.

After 20 years of research, an Egyptian medical doctor named Shefik has found that chemical fiber underwear may cause oligozoospermia in men, casting a shadow over fertility. His research data show that men who wear pure polyester underwear significantly reduce their sperm count at nearly 40% to 14 months, while men who wear semi-cotton and semi-polyester blended underwear decrease their sperm count at about 9% to 10 months, while those who wear pure cotton underwear have no change in semen. In addition, most of the men with semen changes returned to normal 4 or 8 months after changing their chemical fiber underwear.
