Choose underwear carefully to maintain men's sexual ability

Men seem to be used to a rough life-just a sloppy dress and just drag on a casual pair of underwear. In this regard, Dr. Shafik of the School of Medicine at Cairo University in Egypt pointed out that it is best for men not to wear pure polyester underwear because it may inhibit sperm production and affect male sexual function. Previously, Shafiq had been engaged in physiological research on male infertility for 20 years. Recently, he found from a study on "The Effect of Textile Types on Spermatogenesis, Pregnancy and Sexual Activity" that there are significant differences in men's testicular temperatures and plasma hormone levels due to different materials used in underwear. For example horse dildo , men who wear chemical fiber underwear are most likely to have a significant decrease in sperm count; while those who wear pure cotton underwear for a long time have no change in semen quality. The more convincing data is that men's sperm quality can return to normal 4-8 months after taking off chemical fiber underwear. Based on these data, Shafik believes that chemical fiber underwear will temporarily inhibit sperm production. "Although there is no special research on this in my country at present, chemical fiber underwear is obviously not as good as pure cotton underwear in terms of comfort and anti-static electricity." Professor Zhu Jichuan of the Department of Urology at Peking University, chairman of the Andrology Branch of the Chinese Medical Association, told the Life Times reporter. Wan Pingyu, dean of the School of Science at Beijing University of Chemical Technology large dildo , said that chemical fiber underwear will have some impact on sexual function because it is more likely to cause static electricity. Shafik's research confirmed that chemical fiber underwear is prone to generate static electricity, which affects sexual function. However strap on dildo , pure cotton underwear is not suitable for everyone. Although it absorbs sweat nice ass , it is not easy to dry, so men with sweaty physique should not wear it frequently. In terms of color, it is best to choose a light color. Wan Pingyu said: "Dark underpants may be dyed, and the dye will be somewhat toxic. While underpants that are too white are suspected of being excessively bleached. In addition, chemicals may be absorbed after coming into contact with the skin, so light-colored underpants are relatively safe." He also suggested that after buying underwear, it is best to wash it with clean water first, so that some harmful substances can be removed. In addition, style is also important. Compared with briefs, boxers can reduce the restriction and friction on the base of the thighs, and have good breathability, making them a better choice. At the same time, do not choose underwear too tight, otherwise it will also affect the reproductive system. The above "panty rule" also applies to women. Shafik believes that the electrostatic effect of chemical fiber underwear may reduce the level of progesterone in women's bodies, easily leading to miscarriage.
