Many men are wearing underwear, but they don't know why. In fact, wearing underwear is for health. If some men don't wear underwear, it's bad for their health. If you don't wear underwear often, your testicles are always hanging and varicose veins are easy to appear, so wear underwear. It is more suitable for this kind of briefs, because briefs are close to the skin, but briefs are not easy to dissipate heat, and straight briefs are better, which is conducive to heat dissipation. Wearing briefs or boxers has its own advantages and disadvantages, so choose for yourself! However, men's underwear has always lacked healthy design elements. The scrotum and penis are tightly wrapped by double-layer cloth at the same time, which makes the scrotum lose the self-regulation ability endowed by God. The increase of self-temperature leads to sperm deformity, necrosis and decreased fluidity in scrotum. Male infertility is not due to bad guns, but to unqualified bullets. Unreasonable underwear is one of the chief culprits, which has become a global historical problem. Now with men's underwear, you can compete with women's underwear. Men's underwear has more scrotum pockets than ordinary underwear. The scrotal pocket is shaped like the letter U, so it is named U-pants and U-Briefs in English. U-shaped pants make the scrotum fully stretched, that is, separated from the penis, not in direct contact with the thigh, breathable and radiating, freely retractable, and kept 2-3℃ lower than the body temperature; The scrotum stretches freely, playing the role of gentle massage, promoting the secretion of testosterone and the activity of reactive enzymes, restoring the vigorous spermatogenic ability of spermatogonia and enhancing sexual desire. The scrotum bag is made of silk fabric, which can protect testicles from external temperature and humidity, absorb and release invisible moisture, sweat and secretions on the skin, keep the skin clean, and it is very comfortable and natural to wear. Men's underwear can be divided into three types: sports U-shaped pants, which, as the name implies, are special for sports. Scrotum bags can tightly wrap the scrotum to play a role in support and protection. Silk fabrics can quickly remove moisture and cool down, so that the scrotum and testicles can keep dry and cold during sports, and avoid problems such as sperm deformity and necrosis in the scrotum caused by local temperature rise like a small steamer. U-shaped sports bra can fully stretch the scrotum, keep it at 2-3℃ below body temperature, restore the vigorous spermatogenic ability of spermatogonia, and ensure the reproductive health of "sports men". Especially suitable for golf, fitness, spinning, yoga and other long-term sports and outdoor activities, more suitable for active armed police and soldiers. The scrotum pocket of casual U-shaped pants is relatively loose to match the scrotum's expansion due to heat and contraction due to cold, giving the scrotum a comfortable activity space. Suitable for men who often sit in the office and drive, especially in hot summer, the U-shaped pants will always keep the scrotum 2-3℃ lower than the body temperature, bringing a cool and dry comfortable feeling. Health-care U-shaped pants are daily physiotherapy pants specially designed for men with varicocele and scrotal eczema. They can raise the scrotum to a higher position, avoid rubbing against the thigh root, sweat and breathe freely, and dry at low temperature, which can effectively relieve symptoms and play an auxiliary treatment role. Since/kloc-underwear was born in the United States in the middle of the 0/9th century, it has formed an indissoluble bond with women. In the eyes of women, it is regarded as the greatest invention in the world. From costume aesthetics's point of view, underwear can not only increase the charm with the curve of women's buttocks, but also make adult women's figure return to perfect proportion. At the same time, we should affirm the support and protection of underwear to genitals. Some experiments show that if some women have been wearing underwear for a year, their genitals will droop by about one centimeter. Therefore, women should wear underwear to keep their beautiful hips and figure, especially adolescent women who are in the stage of physical maturity. But we should also see that if we don't pay attention to underwear, it will not only damage the charm of the coat, but also damage the perfect proportion of the human body and show its disadvantages. If the size is too small, it will oppress the pudenda, causing poor blood circulation in the lower part of the pudenda, causing pudenda dysplasia, and even causing labia invagination and pudenda dysplasia. At the same time, the heart, lungs and great blood vessels will be oppressed, which will affect the normal development of internal organs. If the underwear material and texture are not suitable, it will also make women's skin allergic and itchy. Therefore, according to my body shape and the size of my genitals, I should choose underwear with moderate elasticity and size. Underwear is too small and harmful to the body, too loose and too big, which can't support and protect the genitals, and it is easy to cause genital deformation. Some experts pointed out that because each woman's genitals are different in size, her dependence on underwear is different. Women with small genitals or flat buttocks may not care about wearing them, but women with full buttocks should not chase this new trend anyway. We know that under the action of gravity, genitals will naturally droop. Without the support of underwear, bloated genitals will inevitably droop after a certain period of time. And pudendal prolapse is a defect in itself for the curvaceous beauty of women. The function of underwear for women is not only to beautify the hip lines, but also to protect the genitals.
