Pure cotton is the best breathable material
The part protected by underwear is also the most 'delicate' place for men. If the material is not right, it will increase friction, cause skin redness and even tingling, and even scratch the skin when it is serious, which is easy to cause common skin disease - "tinea cruris" (a kind of dermatitis in the groin).
The temperature in the scrotum is one or two degrees lower than that in the abdominal cavity, which is the preferred temperature for sperm. Therefore, men's good underpants must meet the standards at two points, one is good water absorption, the other is good air permeability, otherwise it is easy to cause bacteria near the testicles.
It is suggested that the underwear made of silk, Lycra, nylon and chemical fiber should be removed from the wardrobe. Pure cotton underwear is the best choice.
Size to be 'tailored'
Testicles are an organ that is afraid of pressure. When underwear is tight, it will increase the friction between legs.
But underwear is not the more loose the better, but to start from their own body, to find the most suitable size. When the size of underwear will not fold in the private part of men, and it is not close to the body, it is a relatively appropriate size.
Four corner panties protect sperm
In 2012, scientists from the University of Sheffield in the UK found that the sperm concentration of men wearing tight underwear was lower than that of men wearing boxers (commonly known as boxers). Quadrangle underpants can provide relatively suitable temperature for testicles and guarantee sperm quality.
There are many kinds of boxers. In addition to the proper size, it is recommended to choose the one with the mouth closed. The length should be a little less than one or two inches of the crotch. For men with family planning, boxers are the first choice.
It's better not to pick black
The daily mail pointed out that the risk of black underpants is relatively high, especially because rubber accelerators are often used as underpants dyes with poor quality and low price. Black underpants are more likely to cause contact allergies.
In fact, no matter what color of underwear you buy, it is recommended to buy a regular brand. After you buy it, you should clean it before wearing it to reduce the damage of chemical ingredients to the skin.
Tips
Wash every day to prevent bacteria
A dirty underpants may contain E. coli, Salmonella and other bacteria. It is difficult to completely remove them in the normal cleaning process. Therefore, it is necessary to change underwear every day.
About a fifth of men can't change their underwear every day, a British survey found. This will not only aggravate the itching of the skin, but also cause bacterial and fungal infections. When washing, it is best to wash by hand with soap, not with socks and other clothes.
Leave the scrotum off occasionally
Many people wear underwear 24 hours a day. Actually, it is a healthy behavior to take off their underwear properly.
At home in the evening, men can take off their underwear and put on loose cotton home clothes to ensure dry and comfortable skin.
You can also choose to sleep naked at night, not to create a 'warm and sweaty' environment for the scrotum, and keep the testicles dry and cool.

Underwear can't be too tight
Women's vagina, urethra and anus are close together.
Underwear wear too tight, easy to produce frequent friction with vulva, anus, urethra, so that the area of dirt (such as anal and vaginal secretions) bacteria into the vagina or urethra, causing urinary or reproductive system infection.
Underpants are too tight, which can also cause local environment to be warm and humid, providing an excellent place for the growth and reproduction of bacteria, causing vulvovaginal or vaginitis. Therefore, underwear must be loose and moderate.
Pure cotton and modal
Pure cotton is also the healthiest fabric for women.
The underwear made of modal material has good water absorption and air permeability as well as high comfort. According to some data, the absorption and release speed of modal is 50% higher than that of pure cotton, but people with sensitive skin may be allergic.
White is the best color
Leucorrhea is an important standard to judge women's vagina health. It may be a sign of disease that leucorrhea becomes turbid, even yellow and red, which should be found and treated early.
Underwear or pattern of other colors are too flowery, which may affect people's judgment on the white belt. It is recommended to wear light colored underwear, with white as the best.
