The increase in infertility, the age of the age of appropriate age should not be on the child.What is the occurrence of this series of issues?A large part of the reason is related to the reduction of men's sperm. The number and quality of sperm are quietly affecting the birth rate and quality of birth of the population.So, what is sperm "natural enemy" in the process of making people.
In the past 50 years, the average number of men's sperm has been reduced by an average number of sperm.After the 1990s, this proportion increased to 15%, and it was worse. The sperm quality decline. The proportion of malformations and inferior sperm increased, and the vitality, penetrating power, and the pregnancy rate were declining.In the 1970s, the proportion of men and women in men and women was 3: 7, and men were less than half of women; and the proportion of 10 years ago rose to 1: 1, and the situation of male infertility and female infertility was also serious.
Sperm is the ultimate product of the development of male genital cell lines. In the process of sperm, formation, and degeneration, due to the loss of deoxyrum ribosacuucleic acid (DNA), the function of deoxyrum ribosacuucleic acid damage and repair system can no longer be like body cells.Like egg cells, more than 90%of the loss of genetic material can be repaired.Among all the cells of the human body, sperm has such "weakness", so it looks very fragile.
Compared with various other cells, there are many sperm "natural enemies", and the sperm itself is weak, and it is sensitive to a variety of toxic substances.From the middle and late stages of the embryo, the sophisticated cells are always in a rapid division.In the process of rapid sperm, the harmful effects of various harmful factors have increased significantly due to accumulation and accumulation.Research data has confirmed that, compared to X chromosomes, genes carried by Y chromosomes are more likely to change.
The rise and fall of the animal world has provided us with a mirror: the degeneration of high animals and endangered animals, first of all, starting from the decline in sperm quality.For young men, it is necessary to understand these "weaknesses" of sperm.
Due to the application of pesticides and pesticides due to the general application of such harmful substances in the planting industry, it not only endangers farmers, but also affects urban young people. They will directly contact or eat vegetables, fruits and other foods that spray pesticides and pesticides.Victory.The harm of pesticides and pesticides is to reduce the vitality of enzymes in the testicular, reduce the energy supply in the process of sperm production, and change the fine sperm tubes and sperm cells that produce sperm.
The number of motor vehicles such as exhaust gas and motorcycles has increased and entered the family. During the driving process, the vehicles emit a large amount of toxic substance exhaust gas, which can reduce male sexual function and sperm distortion.As for the large amount of industrial exhaust gas emissions, the concentration of pollutants in the atmosphere has increased, causing men's sexual organs.
Electrical appliances, computers, microwave ovens, etc. can cause contact with electromagnetic waves and fluorescent screen rays, interfere with the split of cells, cause seizure of fine seizure of epithelium atrophy, sperm cell distortion, cause sperm -free or abnormal sperm, leading to infertility, leading to infertilityOr terators.
Professor Wang Junnan and his colleagues of Smoke Singapore's National University Environment and Occupation Health Center found that most men suffering from infertility are more than 15%less than that of sperm.It is much higher than normal men.Nicotine and chromium in cigarettes are taken in the body during smoking. After oxidation, they generate highly active free radicals, destroying the genetic material deoxyuraotosacid acid of male sophisticated cells, causing genetic information errors, and thereby giving birth to malformed fetuses.
Like nicotine, alcohol alcohol is also a murderer who damages sperm, which deforms sperm head and tails and reduces vitality.
The temperature suitable for sperm development is about 34 ° C, and high temperature has adverse effects on sperm development.According to Japanese expert reports, since the car is installed on the air conditioner, the sperm quality of the driver has significantly improved is an example.Therefore, high temperature operations, hot water baths, etc. should be treated carefully.
The lack of nutrient sperm is inseparable from nutrients, such as the ingredients of sperm supply sperm, vitamin B12 and vitamin C to promote sperm production, and protect sperm resistance to harmful factors.The types of food should be expanded to avoid single food and unbalanced nutrition.
Many drugs can damage sperm, anti -suppression drugs, diuretic drugs, antibacterial drugs, and drugs that treat heart disease and gastric ulcers have such disadvantages.
Bacteria such as spiral, mycoplasma, and chlamydia invaded the reproductive organs such as men's testicles, seminal vesicles, prostates, etc., causing inflammation, losing sperm loss of normal form, reducing activity, and reducing survival rate.
Drug use of drug use can reduce the level of testosterone in the blood, weaken reproductive ability, and irreplaceable ejaculation, thus infertility.For example, the sexual desire of heroin is 100%inhibitory, and the sexual desire for sexual liga is 96.5%.
