Men's underwear is crucial, yet many men choose them carelessly—as long as they look acceptable and feel smooth to the touch. Selecting underwear is actually a skill. While not as complex as women's lingerie choices, these three points must be considered.
How should men choose underwear? 1. Looseness and tightness
Urologists have observed that many men experience penile deformation, including varying degrees of curvature. The root cause often lies in wearing tight underwear. Under the constriction of tight underwear, the penis endures prolonged pressure—how could it not bend?
How should men choose underwear? 2. Fabric
Egyptian medical doctor Shafik, after 20 years of research, discovered that synthetic fiber underwear may cause male oligospermia, casting a shadow over fertility.His data revealed that nearly 40% of men wearing pure polyester underwear experienced a significant drop in sperm count after 14 months. Among those wearing half-cotton, half-polyester blend underwear, approximately 9% showed reduced sperm counts after 10 months. In contrast, men wearing pure cotton underwear exhibited no changes in semen quality.Furthermore, most men with altered semen parameters returned to normal within 4 to 8 months after switching from synthetic underwear. This study confirms that polyester underwear temporarily suppresses sperm production. It elevates testicular temperature and lowers plasma hormone levels, thereby inducing oligospermia.
How Should Men Choose Underwear? III. Underwear Color
Some prefer dark-colored underwear, yet overlook that colors are achieved through dyes—complex mixtures of various chemicals that inherently contain some toxicity. As for excessively white underwear, it may pose hidden risks due to over-bleaching, increasing the likelihood of developing allergies.
