Many men have a bad habit of not changing their underwear. It is said that they can wear one pair of underwear for a week, resulting in many male related diseases. From the perspective of infertility outpatients, nearly half of the patients are male reproductive diseases. Diseases such as semen non liquefaction, oligozoospermia, and sexual dysfunction are on the rise year by year.
Dr. Shafik of the University Medical School has been engaged in the electrophysiological study of male infertility for 20 years. He found significant differences in testicular temperature and plasma hormone levels between the pure polyester underwear group and the half cotton and half polyester blend group compared to the pure cotton group through a study on the effects of textile types on sperm production, pregnancy, and sexual activity. In the polyester group, 4 patients (36%) had a significant decrease in sperm count by the 14th month; One (9%) of the blended group developed oligospermia by the 10th month, while the semen quality in the control group and the pure cotton group did not change.
However, people with semen changes can generally return to normal after removing polyester containing underwear for 4 to 8 months. After 30 months of intensive research, he believes that polyester underwear has a temporary inhibitory effect on sperm production. Dr. Shafik also believes that the electrostatic field effect of polyester underwear can easily cause a decrease in progesterone levels in pregnant women, resulting in miscarriage.
Polyester can also generate electrostatic fields in penis tissue, which may explain why people who wear polyester underwear for a long time exhibit decreased sexual function. Quickly open your wardrobe and check it out. Clean out all those polyester and blended underwear and replace them with pure cotton products. Of course, if you don't care whether your fertility will be affected by the texture of your underwear, you can ignore it, but this is not a wise move.
