in the past 50 years, the male sperm is almost cut in half, and also at a 2.1% rate reduction annually, mankind is facing extinction threat–
SOS, sperm in SOS
with the worsening of global environmental pollution, human sperm counts were quietly dropped. Pollution of the world, will result in genital anomalies, will bring to the species produce serious disasters. Experts predict that, if human beings continue to damage the environment, then we reproduce in the future may have to be on cell cloning.
sperm faced ruin
growth requires excellent seed crops grow, healthy growth of children cannot be separated from the healthy sperm. However, nearly half a century, people relied upon to deliver sperm extreme landslide occurred, to the human out of the red light. The landslide, was caused by ourselves, that is equal to extinct races of suicide.
in the past 50 years, the male sperm is almost cut in half, and at a 2.1% rate reduction every year. According to statistics, 40, averaging 130 million per millilitre of semen containing sperm in men, later reduced to 66 million. In 1960, less than 20 million per ml of sperm in semen of male 5%. 70-80 generation, increasing sperm count of less than 20 million men. In the 90 ‘s, the world’s increasingly serious environmental pollution, the rate of the 60 5% jumped to cent. To make smooth fertilization of eggs, 20 million spermatozoa is not enough.
at the same time, human sperm quality in recession. Deformities, poor sperm in increasing its viability, penetrating, pregnancy rates were falling, so that the proportion of male infertility is also increasing. Some statistics, 1960 due to consult male infertility only 8%, but now has been as high as 40%. 70 per cent of male and female infertility in patients with 3:7, 90 the proportion had risen to 1:1.
and fewer sperm why
declining sperm count of a direct threat to human reproduction quality. This has attracted experts from different countries of the world’s worries and anxiety. What causes such adverse trends? after many years of clinical study, scientists found that chemical pollution, radiation, electromagnetic waves, noise and other environmental degradation on human sperm is like feral killer, a variety of physical, chemical, and biological harmful factors of pathogenic cause cancer, more quietly against the race continued.
in crowd suffering from infertility, have relatively significant occupational characteristics. According to the Shanghai international peace hospital Urology specialist Professor Cheng Huaijin introduction, engaged in radiation work, high temperature, and exposure to pesticides, paint, paint and other toxic substances, such as lead, mercury, phosphorus, and long exposure times and no protective measures are, the hazardous substances directly affect the reproductive system. Drivers, such as carpentry, electrical, plumbing, construction worker, all populations with a high incidence of infertility. People in these occupations at high temperatures and their susceptibility to infertility in work environment, lack of necessary labour protection has a great relationship. For example, the driver drove regularly go out in the morning and return in the evening, rest and diet there is no law, high tension, will affect the survival rate of sperm quantity, quality and and electrician mild electric shock, water heating, electric welders often touch electric welding, sperm is a role in killing both. In addition, modern society, work and life pace, some working pressure, stress, your body always in a State of fatigue, irregular others work, life, social gatherings, often drunk will affect male hormone secretion, leading to decreased sperm quality, reduce the number.
sperm especially sensitive to high temperatures. According to Shanghai reproductive medical research center Wu Mingzhang Professor describes, in normal physiological conditions and general environment Xia, Yin SAC temperature below temperature 3 ℃ above, is located in Yin SAC in the of testicular and epididymis of temperature also obvious below temperature, this is guarantee sperm occurred and mature of important conditions one, and all improve Yin SAC, and testicular and epididymis temperature of factors, are will may on sperm of occurred and mature manufacturing obstacles. Study finds that bubbles hot bath 3~4 times a week, temperatures above 40 ℃, abnormal sperm head and immature sperm has increased significantly. If long-term work in high temperature environments, regular sauna bath, wear denim leggings, will cause the scrotum and testis and epididymis temperatures affect the formation and maturation of sperm.
in addition, the proliferation of taking them on abuse, malnutrition, sexually transmitted diseases, such as smoking, drug addiction, are considered hidden killer of sperm.
initiatives to prevent sperm killers
modern people living in the dirty air, the body’s immune system is vulnerable to damage. Environmental hormone once it enters the body, will play the role of estradiol, interfering with hormone, reproductive system malformation, male sperm quantity and quality, as well as lead to disorders of immune system function. Faced with the worsening environmental pollution, self-protection . ability should be enhanced and eat carrots, garlic, kelp, mushroom, mung beans and other anti-pollution foods to remove pollutants. Eat more fresh vegetables, is one of the best strategy of self-protection. At the same time, disable the toxic plastics such as polycarbonate, PVC, prevent HIV from into.
prevention of thermal radiation and electromagnetic wave attacks the body, which is that everyone can do. For example, do not have hot water bathing, sauna bath not to wash or less, do not wear tight pants, the attention of heat control. Appliances in today’s society, is not possible to completely cut off from electricity, but is scheduled or in small home appliances can be accomplished. In daily living, to quit smoking and drinking treatment. Be careful of phytotoxicity. Prostitution is strictly prohibited to stamp out rampant sexually transmitted diseases.
at the same time, scientists are working on assisted reproduction techniques in countering the decline of human sperm. According to the Professor of Gynecology and obstetrics hospital, Shanghai Medical University Yan Jingming introduced, such as assisted reproduction, including artificial insemination and in vitro fertilization, and intracytoplasmic sperm injection is noticeable in the egg mixture, where male patients with oligospermia or weak, directly under the microscope will be completed within a single sperm into the egg mixture during fertilization. In this way, male infertility may also has his own children.
