The fabric of men's underwear is very important
The study found that chemical fiber underpants may cause male oligospermia and cast a shadow on fertility. His research data showed that the number of sperm in men wearing pure polyester underwear decreased significantly from 40% to 14 months, while that in men wearing half cotton and half polyester underwear decreased from 9% to 10 months, while that in men wearing pure cotton underwear did not change. In addition, most of the men who had semen changes returned to normal after replacing their chemical fiber underwear for 4-8 months. Polyester underpants can temporarily inhibit spermatogenesis. It can raise the temperature of testis, reduce the level of plasma hormone, and induce oligospermia.
This is one of the consequences of wearing underpants by mistake: causing infertility and depriving you of the right to be a father. But the problem of underpants is not only for unmarried men to pay attention to. Dr. shafik also warns those men who have already become fathers: Polyester like chemical fiber fabric will generate electrostatic field in penis tissue, weaken men's sexual function, and even make you bond with cold sex.
Should cotton underwear be safe? Not necessarily. If you are fat and sweaty, especially if you drive a lot, cotton underwear may cause skin diseases such as eczema and prickly heat. Because although pure cotton absorbs sweat, it is not easy to dry, and bacteria may grow when it is often wet. In addition to bringing you wet discomfort, it may also cause "trouble" in the perineum, such as redness, swelling, itching, etc., which will become your problem.
