The more natural the underwear color, the better.
Male experts say that to maintain the health of reproductive system, it is necessary to choose good underwear and wear it correctly. There are many aspects to consider when choosing underwear. From the color point of view, men's underwear had better choose natural color. Dark underwear dyes are somewhat toxic; White underwear is also suspected of excessive bleaching, and chemicals may be absorbed after contact with the skin. So natural colored underwear is much safer.
Pure cotton underwear keeps dry.
In China, most men are used to wearing pure cotton underwear. But experts point out that cotton underwear absorbs sweat for people who are prone to sweating, especially men who often drive, but it is not easy to dry. Skin contact with wet clothes for a long time is prone to redness, itching, prickly heat or scrotal eczema. Therefore, it is very important to keep dry if you want to wear pure cotton underwear.
Men had better not wear chemical fiber underwear. Chemical fiber underwear will generate static electricity, inhibit sperm production and affect sperm quality.
Men's underwear should not be too tight.
In addition to color and texture, men should not choose underwear that is too tight or airtight, so as to avoid excessive friction between testicles and thighs and pants, or increase the temperature of testicles, thus affecting the production or quality of sperm.
Carefully wash and dry underwear.
Before wearing new underwear, it is best to scald it with boiling water to remove the harmful substances that may remain on the underwear. If you use a washing machine to wash underwear, you'd better put it in a laundry bag and avoid washing it with socks. Don't use too much force when washing by hand, and don't add bleach or disinfectant, otherwise it will easily damage the material of underwear.
When drying underwear, it is best to lay it flat to make it fully contact with the sun, and turn it over after a period of time to make it fully irradiated by the sun, thus playing a role in sterilization. Try not to use the dryer.
