Are British pantyhose really effective?
It is said that Bian Xiao has never used British sweaters and trousers, so I dare not say that they are absolutely invalid. But from the information found on the Internet, there is no good effect, and there is no scientific argument that it is too effective. Also, the penis can't develop any more, and medicine can't be used, let alone just wearing underwear. The male penis length in China is 1 1cm, and the erection duration is 3cm, with an average of 6cm. When erect, the penis is 18cm long and 8cm short, with an average of 12cm. As for the curative effect of premature ejaculation and impotence, it is also suspected of exaggerating publicity.
To treat impotence and premature ejaculation, you should go to a regular hospital, do some related tests and have regular treatment. You can also listen to the doctor's advice on British underwear. Think again, if that works, why doesn't the Ministry of Health recommend it? Why not go to the hospital and become a treatment?
Of course, underwear still has a great influence on male reproductive health. In life, although underwear is small, it is related to the overall situation of health. People don't have much demand for underwear, as long as they are comfortable, but they don't know that tight underwear has become a new sperm killer and one of the factors that constitute male infertility. So how do men choose underwear?
How do men choose underwear?
First of all, the fabric of underwear is very important. After 20 years' research, an Egyptian doctor of medicine named shafiq found that chemical fiber underwear may cause male oligozoospermia and cast a shadow on fertility. According to his research data, the sperm count of men wearing pure polyester underwear decreased significantly to 14 months in nearly 40% of the time, and that of men wearing semi-cotton and semi-polyester blended underwear decreased to 10 months in about 9% of the time, while that of men wearing pure cotton underwear remained unchanged. In addition, most men with semen changes returned to normal after replacing chemical fiber underwear for 4~8 months.
This study confirmed that polyester underwear can temporarily inhibit sperm production. It will increase the testicular temperature and decrease the plasma hormone level, thus inducing oligozoospermia.
This is one of the consequences of wearing underwear by mistake: it leads to infertility and makes you lose the right to be a father. However, the problem of underwear is not just the problem of unmarried men. Dr. Shafik also warned men who have become fathers that polyester chemical fiber fabrics will generate electrostatic fields in penis tissues, weaken men's sexual function and even make you attached to sex apathy.
Should pure cotton underwear be safe? Not exactly. If you are overweight and sweaty, especially if you drive often, pure cotton underwear may cause eczema, miliaria and other skin diseases. Although pure cotton absorbs sweat, it is not easy to dry. Frequent sweating may breed bacteria. In addition to giving you wet discomfort, it may also create "troubles" such as redness and itching in the perineum and become your secret room.
Secondly, the choice of underwear must be elastic and moderate, otherwise it will cause many problems.
How to choose briefs and boxers?
Compared with the compactness of briefs, the looseness of boxers has won the favor of many people, especially male doctors who advocate male friends to wear this style of underwear. The scrotum is very sensitive to the outside temperature, rich in sweat glands and without subcutaneous fat, which helps to dissipate heat.
When the outside temperature is low, it stimulates the contraction of the smooth muscle of the flesh membrane and levator testis, so that the position of the testis rises, and the scrotum skin shrinks into dense wrinkles, which shrinks to the perineum to prevent heat dissipation and help to keep warm. The external temperature rises, the smooth muscle relaxes, the testis descends, and the scrotal skin relaxes in vitro, which is beneficial to local heat dissipation.
Scrotal temperature has a great influence on testicular spermatogenesis. The temperature in the scrotum is about 2 degrees Celsius lower than that in the body, which is the most suitable temperature for spermatogenesis. If tempe
