1.Improve the working environment
The work and living environment is closely related to the human reproductive fertility process, therefore, improving the work and living environment is beneficial to male eugenics. Men who are engaged in long-term high-temperature work or underwater work, or long-term exposure to radiation work, because high temperature or low temperature can affect the generation of sperm, radiation can kill sperm, thus reducing the number of sperm, quality decline.
Long-term exposure to certain chemical substances or toxic substances can also affect the growth and quality of sperm, so men engaged in certain special occupations (high temperature, low temperature, toxic, radiation) should try to improve the working environment, do a good job of protection, to minimize or eliminate the damage to the body due to the working environment.
The electrical radiation of household appliances, the chemical substances released by the decorations (especially stone materials) and furniture, the pesticide pollution of food, the “three waste” pollution of the atmosphere, etc., these pollutions more or less cause damage to the machine. Environmental pollution will also affect the production and quality of sperm.
2, strengthen nutrition
If you choose to eat, partiality, or long illness digestive absorption dysfunction, can make the human body nutritional deficiencies, resulting in some of the nutrients and sperm development is very close to the lack of vitamin A, E and trace elements such as zinc, thus affecting the quality of sperm. Therefore, food selection and partiality should be avoided, and digestive tract diseases should be actively treated.
Protein is the main raw material for the production of spermatozoa. Arginine is the main component of sperm production. Huai yam, eel, cuttlefish, walnuts, peanuts and nori contain more arginine.
Vitamins have an important role in providing raw materials for sperm and semen, promoting the synthesis and chemistry of sperm, enhancing the anti-infection ability of the paragon gonads, and maintaining the metabolic process of sperm, especially vitamin E can regulate testicular function and enhance sperm vitality, which is more conducive to male eugenics. Animal liver, vegetable oil, carrots, tomatoes, pumpkin, lentils, dates, etc. are rich in vitamins.
Trace elements such as zinc and magnesium are closely related to male reproductive function and can affect the production and vitality of sperm When the body is lacking in trace elements or insufficient content, it will affect the production and vitality of sperm, such as long-term zinc deficiency, can cause testicular atrophy, reducing sperm quality. Eat more fish, shrimp, oysters, clams, mussels, kelp, eggs and fungus, walnuts, honey, soybeans, brown sugar, etc. all contain more trace elements.
Animal genitalia, human placenta and eggs are rich in sex hormones and cholesterol and lecithin, which can promote the division and maturation of spermatogenic cells and improve sperm quality, so they can also be eaten properly.
3. Quit smoking and drinking
Smoking can reduce the level of testosterone in the blood and make the penile artery atheromatous changes that cause male sexual dysfunction. Cigarettes also contain many harmful substances that can damage sperm, so smoking can affect the health and development of the offspring, the fertilization of damaged sperm will cause fetal abnormalities. In long-term heavy smokers, the sperm surface membrane will become eroded, reducing sperm motility and survival rate.
The production of alcohol has brought joy to mankind and health to the human body, but the opposite is true, a lot of alcohol or regular alcohol consumption has added a lot of trouble, disease and pain to life, such as male sexual function and eugenics has brought extremely adverse effects.
Occasionally a small amount of alcohol can reduce the sexual inhibition of the cerebral cortex, part of the people can enhance sexual desire, sexual pleasure, but long-term excessive drinking and chronic alcoholism in 50% of male patients with sexual dysfunction, accompanied by chronic liver damage, sexual dysfunction up to 75% of patients, mainly manifested as impotence and non-ejaculation.
Alcohol has a direct effect on the gonads, reducing the rate of testosterone production and increasing the activity of hepatic 5-a-ketoreductase (which degrades testosterone), resulting in the degradation of large amounts of testosterone, leading to a decrease in blood testosterone levels. In non-alcoholic men, a decrease in blood testosterone levels can be measured when the daily alcohol consumption reaches 200 ml, which will show alcoholic gonadal hypofunction over time. Male alcoholism, heavy drinking and excessive drinking will not only lead to sexual dysfunction, but also affect sperm production and lead to infertility because alcohol can cause testicular atrophy and lower testosterone levels in the body.
At the same time, alcohol has a toxic effect on the normal development of reproductive cells, drinking large amounts of alcohol can directly damage sperm, and if the poisoned sperm is combined with the egg, it can cause the fertilized egg to develop unhealthily or produce abnormal fetuses. Modern research has shown that 70% of the sperm in the semen of men who drink a lot of alcohol are not well developed or not very active.
The fact that alcoholism is an enemy of eugenics has been confirmed by historical examples and modern research. In Chinese history, Tao Yuanming, Li Bai, Du Fu, etc. were all intelligent people, but they all spent their lives with alcohol, and their offspring had extremely low intelligence, so it can be said that alcohol is wrong for future generations. In Germany, a survey of 255 children with various diseases found that 928 of them (36.4%) had parents with alcoholic habits.
The emergence of the “Saturday fetus” further illustrates the harmful effects of alcohol consumption on future generations. The term “Saturday fetus” refers to a weekend night in the West. The fetus is often born with congenital defects, lower physical strength and intelligence, high rate of fetal malformations, short body size, ugly appearance, and small head, small eye cleft, small lower collar, heart malformation, abnormal skin pattern, abnormal joint development, growth retardation. Small body size, low intelligence, or even dementia, etc.
It can be seen that alcohol addiction can lead to reduced gonad function, damage germ cells, inhibit sperm production, and directly damage sperm and affect the normal development of fertilized eggs.
From the above analysis, it can be seen that tobacco and alcohol are very harmful to the reproductive fertility process, directly affecting the quality of offspring from the eugenic point of view, it is necessary to quit smoking and alcohol before preparing for childbirth according to the time of the spermatogenic cycle should be at least six months before preparing for childbirth to quit smoking; before marriage and childbirth should not be alcoholic, especially not in the newlywed feast, separated couples reunion, festivals, holidays, etc., after drinking a lot of alcohol to have intercourse and pregnancy. Otherwise. Not only bring pain to the family, but also more importantly, to affect the improvement of human quality.
4, correct bad habits
There is a relationship between temperature and sperm production. The normal temperature of the scrotum should be 32C-33C lower than the body temperature and abdominal cavity temperature, which means that sperm to be generated normally, must maintain a relatively balanced temperature in the scrotum, the temperature of the scrotum for some reason change especially to make the temperature rise can make the sperm occurrence of obstacles.
Experiments have shown that local heating of the testes for 30 minutes a day can have an adverse effect on the spermatogenesis process within 15 – 20 days, while short-term heating of the spermatozoa is reversible, prolonged warming will lead to irreversible spermatogenesis. It has been clinically observed that men who often wear tight pants have a greater proportion of infertility than men who wear non-tight pants in long term hot baths and steam baths, and the same situation exists. The morphological, biochemical, histochemical, and immunological aspects of testicular tissue can be damaged when the local temperature of the testicles is elevated, damaging spermatogenic cells, inhibiting sperm production, preventing normal sperm development, and thus reducing sperm quality.
From the eugenics point of view, bad habits that can increase the temperature in the scrotum in daily life such as wearing tight pants for a long time, taking a hot tub or steam bath for a long time, and riding a hard seat bicycle for a long time should be avoided.
5. Do not abuse drugs
Many commonly used chemotherapeutic drugs can affect the spermatogenesis of the testes, or inhibit sperm maturation and thus reduce sperm quality, such as lisinopril, guanethidine and other central antihypertensive drugs and steroids can affect the function of the hypothalamus and pituitary gland and inhibit the occurrence of sperm; cancer, Maryland, methotrexate, colchicine, cyclophosphamide, vincristine and other antitumor drugs, can inhibit the division of spermatogenic cells, so that spermatogenesis The sperm production can be reduced; Furatantin, aspirin, etc. can inhibit prostate secretion and affect sperm activity.
There are also certain sex hormones that can inhibit spermatogenesis, certain antibiotics that can affect the glucose metabolism process of spermatogenic cells, and certain anesthetics that have a negative impact on spermatogenesis. It can be seen that, from eugenics considerations, men who have not had children should be careful with drugs that have an impact on reproduction and fertility.
