First of all, the fabric of underwear is very important. After 20 years of research, an Egyptian medical doctor named Shafiq found that chemical fiber underwear may cause male oligozoospermia and cast a shadow on fertility. His research data shows that 40% of men who wear pure polyester underwear have a significant decrease in sperm count at 14 months, and about 9% of men who wear half-cotton and half-polyester blend underwear have a decrease in sperm count at 10 months. There was no change in semen in those wearing pure cotton underwear. In addition, most men who have semen changes return to normal 4 to 8 months after changing their chemical fiber underwear.

This study confirms that polyester underwear can temporarily inhibit sperm production. It will increase the temperature of the testicles and reduce plasma hormone levels, thereby inducing oligozoospermia.

This is one of the consequences of wearing the wrong underwear: it can cause infertility and make you lose your right to be a father. But unmarried men are not the only ones who need to pay attention to the problem of underwear. Dr. Shafiq also specifically warned those men who have become fathers: polyester chemical fiber fabrics will generate electrostatic fields in the penis tissue, weakening men's sexual function, and even making you have sex with others. A frigid relationship.

Wear underwear for better sex

Should pure cotton underwear be safe? Not really. If you are fat and sweat a lot, especially if you drive frequently, pure cotton underwear may bring on skin diseases such as eczema and prickly heat. Because although pure cotton absorbs sweat, it does not dry out easily. Frequent sweating may breed bacteria. In addition to giving you a wet and uncomfortable feeling, it may also cause "trouble" such as redness, swelling, and itching in the perineum, which can become a hidden problem for you.

Secondly, the underwear you choose must be moderately tight, otherwise it will also cause many problems.

Many men have deformed penises with varying degrees of curvature. Investigating the reason, wearing tight underwear often is to blame. Under the constraints of tight underwear, the penis has been compressed for a long time, how can it not bend?

Furthermore, the color of underwear should also be treated carefully. Some people like dark underwear, but they neglect that the color is dyed through dyes. Dyes are a hodgepodge of various chemical substances and contain some toxicity. As for underwear that is too white, there may be certain hidden dangers due to excessive bleaching, which increases your risk of developing allergies.

Now you should understand that underwear is no small matter. It has multiple functions, such as protecting sexual organs, reducing friction between thighs and outer pants, and preventing the leakage of odor. Therefore, you must choose carefully and put health first, followed by comfort and style. Remember, wearing the right underwear is a sign of self-care for a man.

Relevant experts have put forward 12 suggestions for your reference:

1. Wear well-fitting boxer briefs or thong underwear to work. Jeans and other outer trousers most commonly worn to work are "matched".

2. For leisure at home, loose flat pants are the first choice. The advantage is that the sexual organs that are usually pressed tightly in the pants can move freely. When hanging out, it is better to wear T-shaped underwear, which can reduce the friction on the sexual organs caused by a large amount of activity (such as walking a long distance).

3. When exercising, it is better to wear sports shorts with good breathability, or tights that are made of a material similar to swimming trunks and are close-fitting and breathable. The purpose is to minimize friction between thighs, crotch and sexual organs. In addition, the underwear specially designed for athletes to wear during sports is also good. The characteristic is that the sexual organs are supported by a three-dimensional triangular cup, and there is an elastic band on the left and right to support the buttocks, which can make your buttocks more masculine.

4. When traveling or traveling, disposable paper or cotton underwear is the best choice. In addition, ordinary white underwear can also be considered.

5. Boxer briefs or flat pants are preferred for sleeping, or sports shorts with mesh design.

Men with thick legs are suitable to wear high-cut briefs

6. Those who are fat and sweaty, especially men who drive themselves, should not wear pure cotton underwear frequently and should choose slippery ones. Use fabrics that are comfortable, sweat-absorbent and easy to dry. If necessary, use pure cotton underwear in key areas to avoid a sticky feeling. In addition, a kind of fabric called Modal has a comfortable feel and is quite close to the texture of pure cotton. It absorbs and releases moisture 50% faster than ordinary cotton, so it is also worth recommending.

7. Men with thick legs are suitable for wearing high-cut briefs, which can make the legs look longer.

8. Tight elastic long-leg underwear, the length of the trouser legs can reach the center of the thigh, which is conducive to tightening the thigh muscles and shaping a toned body shape. It is suitable for young men who love bodybuilding sports.

9. No matter what style, it is best to choose light-colored underwear. The lighter the underwear, the less dye is used and the safer it is to wear.

10. Newly purchased underwear must be washed before wearing to prevent accidents such as allergies.

11. Give underwear a holiday at the right time, such as during exercise and sleep. Not wearing underwear when exercising can minimize the friction between important parts; not wearing underwear when sleeping, the exposed skin can absorb more nutrients, promote metabolism, and create a cool environment, which is conducive to the spermatogenesis process of the testicles. It can also relax your limbs and help you enter deep sleep, which is why health experts advocate "sleeping naked".

12. Be careful when cleaning underwear. For example, it is best to wash them alone and not mix them with other clothes; wash them by hand and do not bother using the washing machine; avoid soaking them in washing powder for a long time to extend the life of your underwear.
