One, the degree of sparseness of the beard and sexual ability related?

About the beard, there are a lot of rumors on the Internet, including a rumor that the more dense the male beard, the better the sexual ability, really? What determines the amount of male beard? After the male into puberty, the secondary sex characteristics began to develop, the beard also appeared. The number and growth rate of the beard is mainly related to these two factors:

One is the genetic factor. The number of beards depends on the number of hair follicles, and the number of hair follicles is determined by genes, which basically can not be changed later.

The second is androgen. Prompting the growth of male beard is dihydrotestosterone, which can stimulate hair follicles and constantly produce hair. In contrast, dihydrotestosterone is derived from androgens, and when androgens are secreted in abundance, the beard grows fast and thick.

So, does a thicker beard mean better sex?

Men's sexual ability is a variety of factors, in addition to androgen levels, but also includes age, sperm count, sexual activity, and even a person's personality traits, emotional state will affect sexual ability, so you can not rely on the mustache to determine the ability of strong or weak.

Two, shaving every day, life longer?

There are also rumors that the frequency of shaving how much will affect the life, some people think that the more frequent shaving the longer life, because androgen is strong, and others think that shaving fewer times the longer life, because this reduces the chance of infection. In the end, which statement is right? Shaving is not related to life expectancy?

There have been studies done on this issue. A team of researchers from the University of Bristol in the UK looked at 2,438 middle-aged men and found that men who didn't shave every day had a higher chance of developing cardiovascular disease than those who shaved every day. After 20 years of examination, 31 percent of those who shaved at least once a day died, compared with 45 percent of those who did not shave daily.

So does this study solidly establish that people who shave less often, live longer? Not really!

At first glance, shaving seems to be related to life expectancy, in fact, this experiment did not exclude other factors infected, such as the existence of underlying diseases, whether the subjects smoke, alcoholism, etc., whether there is a relevant family history of disease, alone compared to the frequency of shaving, and can not be proved to affect the length of life.

What factors affect life expectancy? Associate Professor Wang Liping, Chief Physician of Infectious Diseases Department of Xuzhou Medical University Hospital, introduced that genetic factors, dietary and nutritional factors, environmental factors, lifestyle, and psychological factors can all affect a person's life expectancy. Therefore, a long and healthy life depends mainly on oneself, optimistic mood, good lifestyle, eat healthy, all these can give life gain.

Three, two or three questions about the beard

1, men do not grow a beard is a pathology?

Is it morbid for a male not to grow a beard, it needs to be judged in the context of the whole physical development. If there is just no beard, but the reproductive organs, laryngeal bulge, voice and so on are normal, but it is not a pathology.

But if you don't have a beard, and your secondary sexual characteristics are not obvious, and you don't develop even after puberty, you may have a problem with the secretion system that regulates sex hormones, and you need to go to the hospital for checkups and treatment.

2, the beard will be the more shaved the thicker, the more grow faster?

Shaving doesn't change the hair follicle, so it doesn't change the thickness, color and speed of the hair. It's just that hair grows out from the follicle at the bottom, and the cross-section will look visually thicker to the naked eye.

3. Why do girls grow moustaches, is it a disease?

Mustache and androgen related, and regardless of men and women, the body will exist in estrogen and androgen to, so the female growth of beard is not an odd phenomenon. Generally speaking, androgens in the female body will promote armpit hair, pubic hair and even libido production. Once the androgen is too high, it may also lead to the growth of beard.

The high level of androgen in women may be related to staying up late and consuming foods containing androgens such as animal offal and animal genitals, which can be adjusted and improved through lifestyle habits. However, if there is no change even if you change your lifestyle habits, it may be related to polycystic ovaries and insulin resistance, and these to can lead to high androgen secretion in women. If the situation is serious, it is recommended to seek professional medical help.

Four, shaving also have to pay attention to

Shaving before, remember to wash the face, so as to avoid the face of the residual dirt, dust will be on the skin caused by the stimulation of infection. And washing your face before shaving may also keep your skin moisturized and your beard supple, making it easier for your beard to fall off.

There should be no rush to shave in the morning, and it's best to shave 20 minutes after getting up. Just get up, after a night's rest, the reproductive function is vigorous, beard growth is also fast, after 20 minutes to half an hour consumption, the body androgen is relatively stable, at this time shaving, not so easy to grow out.

The razor is a personal item, the use of the process, may scrape the skin, if contaminated with blood, and mixed with others, easy to spread the disease, so it is best not to share a razor with others.

Shaving is not as good as shaving shorter and cleaner, the shorter the beard, the easier it is for the new stubble to grow into the skin, which can cause razor bumps that can be very painful.

Growing a beard is one of the manifestations of male secondary sexual characteristics, sparse and dense with heredity and androgens, and sexual ability has no relationship. The frequency of shaving has nothing to do with life expectancy, and daily attention to screening, do not listen to rumors.
