Male infertility, threaten human

    In recent years, studies have found that male sperm quantity, quality plummeted, male infertility, more and more likely to become the greatest threat to mankind in this crown of creation.
    
In 1991, jointly held by WHO and other agencies "environmental impact of an international seminar on reproductive health," the scientists warned: The quality of human sperm declining! Professor at the University of Copenhagen Skak report: 52 years, the decline in human sperm density 41.5%, 19.1% decreased volume of ejaculate.

10 years ago, some American researchers have to persuade people to do not have to worry about sperm quantity. But today, although whether the decline in sperm count for men, the controversy has not completely over, but the scientific community has put it as a big issue to look at.

In March 2002, the British Medical Research Council in a research report said the British men's sperm count in the past 50 years, a decrease of more than half, the same phenomenon also occurred in other developed countries. Reported that the Scottish born after 1970, men, fertility over the last century, a man born in 50 years reduced by 25%, the number of sperm at an annual rate of 2% decline. The Japanese scientists found that 30 to 50 year-old Japanese man, per milliliter of semen contains 84 million sperm, while the 20-year-old man, from top to bottom is only 46 million, nearly half, making a significant increase in male infertility.


According to statistics, male infertility patients in China has reached 8% of the population, fertility, about 35 million people. In December 2003, "Chinese men of science" magazine published a report entitled "549 college students in Chengdu sperm quality survey" report, the report said unmarried male college students in Chengdu in the future the incidence of infertility may be higher than the current reported in the literature 12% ~ 16%, or even more than 1 / 3.
  
According to Guangzhou Second People's Hospital Center for Reproductive Assisted Reproductive statistics, Guangzhou male sperm count per milliliter of semen contains from 50 years ago, 100000000-200000000, reduced to the current 60 million to 100 million.

In the same time, the sharp reduction in sperm count, sperm quality is also quietly decline. Shanghai Human Sperm Bank detected in the samples provided by donors, rapid movement in sperm count, sperm liquefaction features radiate downward trend; on the contrary, which contains the number of micro-organisms and pathogens is increasing. Deformed, increasing the proportion of poor-quality sperm, vitality, penetrating power, pregnancy rates are decreasing, which makes the proportion of male infertility increased year by year. 70s of last century the ratio of male and female infertility patients 3:7,90 years the proportion had risen to 1:1.

Status of male semen has been a gradual lowering of the basic medical profession recognized by the world's National People's Congress representatives, academicians, said Zhong Nanshan, not without worries, if you do not take the appropriate solution, the next 50 years, China will have more of life can not be孩子. But scientists believe that the current evidence that these are recognized by chance or not conclusive, it does not reflect the overall male semen. The various studies testing methods, testing methods are not uniform and standards, testing process and personnel have not been unified, this conclusion is not sufficiently scientific, authoritative, accurate. To get scientific, comprehensive and objective conclusions through rigorous studies to sound a clear male reproductive health related issues.
     
Male sperm are the fastest growing cells in the human body, but also the most vulnerable to various internal and external environment changes, the changes in sperm quality is a barometer of male reproductive health, reflecting the quality of life of modern man. Then, the male "sperm shortage crisis" is concerned, who is the "culprit" mean? Up to now, affecting male reproductive health is not the real reason is very clear, although it is known endocrine diseases, genetic diseases, immunization, infection, trauma, nervous system disease, cryptorchidism, varicocele, liver and kidney and other chronic diseases, drugs and radiation therapy, environmental pollution, environmental hormones, malnutrition and over-nutrition, psychological factors can affect male fertility, but the To date there are still 46% of the causes of infertility could not be identified. Permeate all kinds of clothing, food, shelter, the negative factors have been clearly exposed to the negative impact on male reproductive health. There is a considerable portion of food can affect fertility, such as food additives, coloring agents, preservatives, and some agricultural products may be of synthetic pesticide residues chemical contaminants.
      
In addition, people in daily contact with the material are also a lot of damage to reproductive function, mainly caused by the chemical industry from the air, water and other environmental pollution, as well as a variety of radiation everywhere. High concentrations of estrogen contamination have men rise to various adverse effects, the River Thames in London because of the people contained in oral contraceptives estrogen through the life of water into the river, resulting in high levels of estrogen in the river, polluting the downstream water resources, resulting in downstream areas male high rate of disease incidence. Recently, the Finnish researchers found that regular shampoo and other cleaning products commonly used in alkylbenzene Ethoxy can play a similar role of estrogen may cause male infertility and sperm count reduction. The study also found that British physicians, carbonate substances have estrogen-like chemical structure. The men's "life signs" --- smoking and drinking on male reproductive health constitute the most common threats. In addition, drug abuse and sexual health products should not be overlooked.
     
Men than women generally lower quality of life, this is also a cause. In contrast, the mean sleep less, do not pay attention to diet, participation in sports has little time to accept the low frequency of such physical examination. High levels of education of male sperm count is lower than the relatively low literacy populations; urban household men, use of electrical appliances more than a few men, nervous men, their sperm count and sperm normal morphology percentage will be lower scoring than these factors, less men. And the high level of education, urban living, more appliances and other factors are associated with the overall progress of society emerged, and this supposed to mean that the progress of society must be based on the degradation of male reproductive health as a cost?
     
Significantly decreased the level of male fertility is a harbinger of many diseases, or warning, male reproductive health situation of grave concern to everybody has become a social problem. At present people are concerned about the level of male reproductive health are far less female attention and concern only the society as a whole male reproductive health, be possible to achieve physical and mental health throughout the population, enhance the people's health and fitness.
