Will the mankind die sonless in 50 years? Man's sperm has serious problem
Reporter Zhao shake the space discipline Shuangcheng

"If went on like this again, the mankind should died sonless 50 years later! " July 22, the intersection of Ministry of Public Health and the intersection of Chinese-Japan Friendship Hospital and the intersection of andrology and chief physician, engaged in, afford to revitalize noon the intersection of professor and worry when being interviewed by " life Times " reporter by the intersection of sperm and Cao of quality research 15 year.

The reason why Professor Cao says so, because recently, the news that the precise source of the domestic sperm bank is in short has seen all newspapers again and again, one of the reasons is that a sperm which donates the precise one is off quality. It is reported, the wish of Shanghai does not exceed 21% donating the qualification rate of the precise one, the donation qualification rate of the sperm bank of Henan is about 22%, but the statistic of the sperm bank of Beijing reveals, it is less than half to screen the number of people that can draw the sample tentatively, can become qualified to support the smart volunteer about 15% finally. "It is very serious that male sperm's quality drops now, but people do not pay attention to this at all. "

Even if last a gleam of hope of the sterile patient's of actually the human sperm bank, nowadays it went wrong, will the mankind really wither away because of this?

Sperm's quality drops year by year

The sha Barker of Danish scholar Niels finds after analyzing 21 countries in the world in 1938-1990 in nearly 15,000 people's seminal fluid quality report, the male sperm's number has been reduced in 50 years by more than 40%. Among them, seminal fluid quantity has been reduced by 20%, sperm's density is from 113 million 66 million reduced to 1990s per ml in 1940. 2003, " International studies of environmental impact on reproduction " held in World Health Organization Have, the scientists seriously send out the warning again: Global human sperm's quality is dropping constantly --The density of sperm of per ml of seminal fluid drops to 50 million from 113 million, has dropped by 62%.

In recent years, American-European countries' research to sperm emerge in an endless stream too, almost every several days on have the latest research report make, let people think that there is a factor influencing sperm's quality in life everywhere. The comparison recently " It is hot " Subject age and weight impact on seminal fluid quality --Man the intersection of sperm and quality begin, worsen from the 35 year old, fat man appear the intersection of sperm and quantity it passes low dangers to be 60% high than normal people, sperm's unusual probability is 40% high.

Research and these results of the scholar of our country are similar surprisingly. National people and the intersection of Family Planning Commission and the intersection of science and technology and in until 39 cities and counties 11726 sperm of people go on, find analyze, altogether from 1981 to 1996 research institute, our country's male seminal fluid quality is dropping at the speed of 1% for every year, decreasing amplitude is more than 40%.

"Although these data may come from different research approaches and standards, the conclusion drawn is a bit terrifying, but global male sperm's quality drops is that one confirms undoubtedly fact. " Chief physician of BJ Union Hospital urology surgery Li HongJun tells reporters, several decades ago, every 100, to only bearing the problem in storing in by 5-8 in the couple, and these figure rose to 10 to the above in recent years, quite a few of among them because the husband's sperm goes wrong. "All parts of the country treat sterile clinic increase, number of people that go to a doctor increase too, all these reflect from a side sperm's problem is becoming more and more serious. "

" don't let men become the endangered animals "

At the seventh Chinese medicine andrology of Guangdong held a few days ago, skill exchanging meeting of andrology of combining traditional Chinese and western medicine for the fourth time, a group of data make the person shocked: According to the survey of 19,000 newly-married families in Guangdong of family planning network, 14.7% face the sterile difficult problem, this compares with national data 10% that Center for Disease Prevention and Control of China announce, morbidity is 47% higher.

Cao revitalizes a professor tells reporters, he pays close attention to the male sperm's quantity since 1990 noon. 15 years later, it was 2006, found the male sperm's quantity dropped by 22% on average. This figure makes him very startled, send out too " the mankind will die sonless 50 years later " Judgement. Shanghai the intersection of university and Da Liu, professor of sociology, face at one academic meeting using abroad studying viewing of house, raising a cry of warning healthily especially: " don't let men become the endangered animals " .

Even if the problem is not so serious, but the male sperm's quantity drops will bring a lot of social concerns, for example will influence and raise healthier, better educated children. Raise healthier, better educated children, follow " fetch long in being short, fetch the specialty in being long " Principle,sperm quantity drop possibilities which will reduce pregnant,but reduce to can be made proportions of sperm outstanding not dropped sperm quality relatively too generally. In addition, it will influence the quality of the people even more that sperm's development is bad, defect, many kinds of questions such as being retarded might have related to sperm after the deformity, stillborn fetus, premature delivery, stillbirth and born of foetus.

What sperm which has hurt the man is it

Then, what reason causes the male quality of sperm to drop day by day?

HongJun Li point out food pollution, live pressure, strengthen, late marriage and childbirth become common practise, cause the reason that male seminal fluid quality drops fast. "Also some influences seminal fluid quality because of job that is engaged in, for example fit up the trade, dept. of radiology of the hospital,etc.. " Li HongJun says, " other, unhealthy life style is to cause one of the male sperm murderers whose quantity drops too, for example smoke, get drunk etc. for a long time. "

Cao revitalizes a professor combines domestic and foreign multiple research to point out, besides those obvious reasons noon, there are some details often neglected in life, in fact the impact on male sperm is far-reaching too.

Use the mobile phone for a long time. The high-frequency microwave impact on male reproduction function that the mobile phone launches out is very obvious, can make sperm's quantity reduce in a large amount, sperm's vigor is insufficient seriously. American scientist once tested in Bombay of India, found finally, it is longest to use the mobile phone (over 4 hours of every day) Man,minimum in quantity in sperm,50 million sperm at seminal fluid per ml, and the sperm has very poor quality, the quantity of sperm of some people among them is even less than 20 million for each ml.

The car exhaust keeps in touch. Italy that the intersection of Les and researcher of university the intersection of toll gate and man of work carry on the investigation in expressway to 85, find their sperm's quantity and other young and middle-aged men of the same area have no difference, but sperm's vigor is weakened, therefore their fecundity drops correspondingly.

Bath too high water temperature ' Sauna bath) . Situations general,at testis sperm must could developments normal, will die if the temperature is too high. People are when having a bath, the water temperature is often higher than this temperature, especially sauna bath, unfavorable to the growth of the sperm, even will cause precisely very much, cause sterility.

" electronic fog " Danger. In recent years, the scientist discovers, various electronic apparatuses, including air conditioner, electronic computer, refrigerator, color TV set, laser photo-typesetting and electric blanket,etc., probably produce different wavelength and electromagnetic wave of the frequency in a large amount in the course of using --" electronic fog " . Such electronic fog floods in the space, it is a kind of thing that can not see, can't feel, smell, it is apt to cause physiological function of the human body disorderlily, lead to the fact the endogenous meticulous afterbirth of testis is unusual seriously.

Besides these above-mentioned reasons, the habits and customs of wearing close-fitting jeans and chemical fibre pants for a long time, riding the climbing bicycle for a long time, using perfume and cosmetics etc. may do harm to male sperm. Especially what deserves to be mentioned is, a lot of young people like putting the notebook computer on both legs and operating now, very apt to improve the testis temperature like this, the impact on sperm is very bad too. Also the expert points out, it is enough to let the male quantity of sperm be dropped to drive continuously to some extent.

Protect sperms, start from minor matter

A lot of people place hoping on the human sperm bank, but if really enter concrete links now, will find a lot of difficult problems. First of all, the intersection of sperm bank and the intersection of sperm and shortage, in a lot of place being may on being getting very much difficult to make an appointment; Secondly, not clear enough to the source of the sperm, it is difficult to settle down while using: What is to be done if the child bearing it have questions? If child and father grow more and more as what if? If the child has known one's own life experience, how should parents explain? And the child is not love crystallization of wife and husband, in case the emotion breaks, will the husband leave children alone A series of concrete and miscellaneous problem all probably come with this small sperm together, plan to " borrow and give birth to the son smartly " Couple make good preparations?

In order to prevent perhaps the question and awkward presented, the men had better pay attention to changing the life style since present, protect sperms. But in fact, a lot of men have not realized this.

"The question has been already very severe, but I find people did not pay attention to this at all. " Cao revitalizes a professor says, " a lot of men like smoking, drinking, washing the sauna now noon, the mobile phones are all hung on the waist too, hardly realize the injury to the sperm of electromagnetic wave of the mobile phone accumulates over a long period, more terrible than the X-ray. "

British scholar Wynes proposes, men should start from minor matter in life, protect one's own sperm. For example by bike at if you can't want, wear with cushion without being had by shorts,and last function good bicycles damped; Place the mobile phone on the jacket to wrap up; Don't put the notebook computer on the knee; Don't wear close-fitting trousers,etc.. In addition, eat more quality that green vegetables contribute to promoting the sperm, because contain the composition that vitamin C, Vitamin E, zinc, selenium,etc. facilitated the sperm growing up in green vegetables. The nut, fish are rich in 3 fatty acid of Europe's rice gal, should eat more too, all these facilitate sperm's cells growing up.

Have also published an article on the websites of the State Family Planning Commission, specially teach men how to resist the electromagnetic radiation that the computer produces: If operating the computer at ordinary times, keep the not less than 70 centimetres distance with the computer screen, and keep the not less than 120 centimetres distance on both sides behind with the computer; Change the new computer less in radiation and install and strain the color board specializedly; Don't put the metal articles without fixed duties in the room, so as not to form the reflection again of the electromagnetic wave; The computer screen don't be too bright; Notice and ventilate in the room; Put plant or water near the computer desk and absorb the electromagnetic wave that the computer generates; Wash the face in time, remove the electromagnetic radiation particle absorbed on the face; Drink two cups of green tea every day, take a tangerine, because contain the radiation protection material in the tea, the tangerine contains the antioxidant composition.

And what shall do the intersection of sperm and the intersection of man and friend that quality problem perplex already to those? The white spring professor of the reproductive medicine center of the third hospital in Peking University points out, meet the question and don't be nervous, because some of this kind of states are permanent, some are only temporary. There are a lot of reasons of low quality to cause the temporary sperm, include venereal disease, getting drunk, smoking, working overloadingly, high-temperature environment, high strung of the pants, insomnia, working and mood pressure,etc.. The patient that sperm's quality is on the low side can improve sperm's quality by training the healthy life style on one hand. On the other hand can improve sperm's quality through the way that the medicine is treated. Really not all right consider auxiliary reproduction technology.
