Before pregnancy, please be prepared to lay a good foundation for the future baby's health and find out the health status. In the first few weeks of pregnancy, you may not even know you are pregnant. However, during this period, the development of the fetus is the most fragile. Therefore, if you are pregnant, you should pay attention to early maintenance in your daily life.

Experts attending the meeting pointed out that in pre-pregnancy preparation, it is first necessary to maintain a normal weight commensurate with height within six months before conception. If I am seriously overweight or underweight, I should see a doctor and get advice on how to reach a normal weight. If you have a chronic disease, you must tell your doctor before you plan to get pregnant and follow the doctor's advice. Those who usually take birth control pills must stop taking them completely 3 months before they are ready to conceive, so that the body can return to normal menstrual cycle. It's best to wait until you have three menstrual cycles before getting pregnant. In the meantime, other contraceptive methods can be used.

Pay attention to nutritional supplement

As the most populous country in the world, China has a high incidence of birth defects. Test data show that about 200,000-300,000 children with congenital malformation are born every year in China. In addition, defects only appear in a few months and years after birth, and the total number of children with congenital disabilities is as high as 800,000 to 654.38+200,000, accounting for 4%-6% of the total number of births every year.

At the seminar, Professor Ceser, a famous Hungarian geneticist, announced his first scientific experiment to prevent human deformity in the world. He used the formula of pregnant women's multivitamin, Ailurovir, and conducted an eight-year clinical study on more than 5,000 women of childbearing age. The results show that taking multivitamin supplements from the early pregnancy can obviously reduce the neural tube malformation of newborns by more than 92%, and reduce the incidence of pregnancy reactions such as nausea, vomiting and dizziness by about 54%.

Therefore, in addition to the regular diet before pregnancy and timely nutrition supplement, it is also important to take multivitamins to prevent deformity.

Don't overdo it.

From the beginning of preparing for pregnancy, we will blindly eat fruits and various supplements to achieve the goal of maternal and child health and safety. Now that living conditions are good, Shanghai expectant mothers can try their best to make up for it. According to Professor Wang Defen of Shanghai No.1 Maternal and Infant Health Hospital, many pregnant women blindly over-supplement nutrition, and more rest and less exercise on weekdays, more than half of them are overweight in clinic, especially pregnancy-induced hypertension and diabetes.

It is very correct to supplement nutrition before and during pregnancy, but it is not good to blindly eat a lot and aim at the mother and fetus. Professor Wang introduced that it is normal for pregnant women to weigh less than 12.5 kg before delivery, and above this figure is overweight, which is likely to give birth to overweight babies. Therefore, the daily diet and tonic should be carried out regularly under the guidance of a doctor.

Traditional ideas make most of us women become passive pregnant after marriage, so we can't discuss pregnancy planning, let alone pre-pregnancy physical exercise. After pregnancy, many women find that their bodies are not suitable for childbirth, or may affect the development of the fetus. As a result, they can only reluctantly give up what they love and terminate their pregnancy. There are countless such examples in real life, which are not only family regrets, but also bring great harm to women's health. Here, we especially remind every couple who are planning to get pregnant to pay attention to the following matters as much as possible before getting pregnant:

Lose weight:

For women who are overweight, we must make a careful weight loss plan before planning pregnancy and strictly implement it. Because obese women are prone to gestational diabetes after pregnancy, it will not only do harm to the health of pregnant women, but also cause fetal development or maternal metabolism disorder, resulting in fetal hyperinsulinemia and macrosomia.

Therefore, every woman who plans to get pregnant and weighs more than the normal standard should pay attention to reducing the intake of fat, starch and sugar food three months before she plans to get pregnant, and strengthen physical exercise or exercise so that her weight can return to the normal standard before she can get pregnant. The husband should help his wife arrange her diet reasonably, and exercise or exercise with her before pregnancy to meet the requirements of physical fitness. We believe that the babies of these couples must be smart and lovely normal babies.

Exercise:

Traditional ideas tell us that most women will try to reduce physical activity or exercise when they are pregnant. With the progress of science and medicine, more and more evidence shows that if both husband and wife can do proper and regular physical exercise and exercise for a period of time before planning pregnancy, it can not only promote the rational distribution of hormones in women, ensure the balance of hormones in women during pregnancy and the smooth implantation of sperm, and avoid early pregnancy abortion, but also promote the development of the fetus in pregnant women and the flexibility of the baby's body in the future, and reduce the difficulties and pains of pregnant women during childbirth.

At the same time, proper physical exercise can also help husbands improve their physical fitness and ensure sperm quality. Therefore, for any couple who plan to get pregnant, they should have regular exercise for a certain period of time before getting pregnant. For example, in the first three months of pregnancy, both husband and wife plan to do appropriate and reasonable exercise or related physical exercise, such as jogging, aerobics, swimming, Tai Ji Chuan and so on. In order to improve their physical fitness and lay a solid foundation for pregnancy.

Pregnancy and childbirth are the most important things in a woman's life. Most people often say this when evaluating women: "A woman can only be regarded as a complete and mature woman if she has gone through the process of love, marriage, pregnancy, childbirth and motherhood."

A large number of studies show that women's psychological state and emotional changes during pregnancy directly affect the development of the fetus in the body and the development of the personality and psychological quality of the child after adulthood. From this perspective, women's good psychological state during pregnancy not only affects pregnant women, but more importantly has a direct impact on children.

If both husband and wife want to have children as soon as possible after marriage, both sides should make psychological and spiritual preparations, including:

1. Accept the special changes during pregnancy: the wife's physical changes, diet changes, emotional changes, lifestyle changes and increased dependence on her husband.

2. Accept the changes in the future living space: the birth of a small life will make both husband and wife feel that their living space and freedom are smaller than before, and it will often be difficult to adapt for a while.

3. Accept future emotional changes: After the child is born, either husband or wife will consciously or unconsciously transfer their emotions to the child, thus making the other party feel that their emotions are missing or not taken seriously.

4. Accept the increase of family responsibilities and due obligations: A pregnant wife needs her husband's understanding and consideration, especially the physical labor that the wife can usually do will be transferred to her husband during pregnancy; After the child is born, the obligations of both husband and wife to the child and the family increase with the passage of time.

Whether you are looking forward to pregnancy, or have carefree thoughts about it, or you are confused, worried, afraid of what may happen, or even pregnant before you have made any basic preparations, even so, once pregnancy becomes a reality, you should accept it happily. You know, pregnancy and childbirth are not diseases, but a normal physiological process, which almost all women in the world have experienced or are experiencing or will experience. Meet the arrival of pregnancy and childbirth with a peaceful and natural attitude, treat the changes during pregnancy with a happy and positive attitude, and firmly believe that we can give birth to a little life representing the future and complete the mission of bringing him safely to this world. This is what we need to do psychologically. This kind of psychological preparation is for both husband and wife. A husband's full psychological preparation can help his wife get through every stage of pregnancy smoothly and lay a solid foundation for the child's future growth and development.

From woman to wife, from marriage to pregnancy, from childbirth to motherhood, all changes are natural processes and stages of life experience. Therefore, whether we are newly married couples or married couples for several years, whether we are wives or husbands, as long as we accept these natural facts and processes with a natural and peaceful mind, think with a smart brain, communicate with our life partners in a timely manner in a way that we can communicate, and be alert to possible problems or contradictions in each process or stage and deal with them in time. I believe that every couple will face what is happening in front of them with a very healthy attitude; Every couple will support each other, and it is not always smooth and safe to spend every natural stage; Every couple can keep their best when they get married.

Early pregnancy refers to the first three months after conception (that is, 12 weeks), also known as early pregnancy, which is embryonic period, so it can also be called embryonic period. Any injury during this period may affect the normal development of embryos, and even cause early abortion or congenital malformation, so it is very important to ensure the health of early pregnant women.

First of all, we should pay attention to the nature and conditions of early pregnancy women's work. Anyone who comes into contact with harmful substances, such as mercury, benzene, radiation, noise and other working environments, should apply for temporary transfer from these jobs to avoid these harmful factors at least affecting embryo development and causing teratogenesis.

Secondly, we should be happy and relaxed. People who have pregnancy reaction in early pregnancy (that is, "morning sickness") will gradually return to normal after 3 months as long as they are treated properly. In order to avoid or reduce gastrointestinal discomfort such as nausea and vomiting, we can take the method of eating less and eating more meals, pay attention to light diet, and do not eat greasy and spicy food, but we must insist on eating, otherwise it will affect the health of pregnant women and is not conducive to embryo development. Pregnant women can eat some sour food, such as bayberry, citrus, vinegar and so on. Increase appetite and help digestion. Sometimes you can take some vitamin B complex and vitamin C or calcium to supplement your nutrition. Vitamin B6 can reduce pregnancy reaction. Don't eat "antiemetic drugs", "secret recipes" and "folk remedies" indiscriminately to prevent adverse consequences.

Pay attention to avoid early pregnancy infection, especially viral infection. If pregnant women in early pregnancy suffer from rubella, it will lead to congenital heart disease, microcephaly, nervous deafness, mental retardation and so on. If pregnant women have a serious cold in the early pregnancy, it will cause fetal cleft lip, cytomegalovirus, hepatitis B virus and so on. , can lead to fetal abortion and deformity. Therefore, pregnant women in early pregnancy should pay attention to hygiene, avoid going to the streets or making house calls, avoid contact with patients, and prevent the spread of various diseases. Once you get sick, you need to see a doctor for treatment, which means you are pregnant and can't take medicine by yourself. You must follow the doctor's advice.

In addition, family members should care about early pregnant women, especially husbands should be considerate of their wives, and it is not advisable to have sex in the early stage of pregnancy, so as to avoid miscarriage and help pregnant women get rid of pregnancy reaction and get through the early pregnancy stage smoothly.

In order to give birth to a healthy and intelligent child and protect the mother's health, pregnant women should pay attention to the following "ten taboos" when eating.

First, avoid partial eclipse: pregnant women are picky eaters, and long-term partial eclipse will cause malnutrition and affect fetal growth. Therefore, pregnant women should be rich in protein, vitamins, calcium, iron and other nutrients and digestible foods, such as eggs, thin, bean products, fresh fish, peanuts, fresh vegetables and fruits.

Second, avoid drinking cola: pregnant women who drink cola drinks too much will damage their embryos, because cola drinks are mainly made of cola nuts, and cola contains 2.6% caffeine and alkaloids such as clonine. It can enter the fetus through the placenta, endangering the normal development of fetal brain, heart, liver and gastrointestinal organs.

Third, avoid overnutrition: pregnant women eat too much meat, fish, eggs and sweets, which can increase the level of catecholamine in the body and cause fetal cleft lip and palate; Pregnant women eat too much exercise liver, and vitamin A in the body increases obviously, which can affect the development of fetal brain and heart, as well as genital malformation. Therefore, pregnant women should not eat too much, but should be full of nutritious food.

Fourth, avoid drinking coffee often: Caffeine in coffee can act on embryos and combine with deoxynucleic acid in cells to cause mutation. Pregnant women often drink coffee, which is at risk of miscarriage and teratogenesis.

Avoid smoking: There are hundreds of harmful substances in cigarette smoke. Smoking or passive smoking by pregnant women will seriously affect the unconscious development of the fetus. According to statistics, more than 8,000 fetuses worldwide die from smoking or passive smoking every year. This is because carbon monoxide and nicotine in the smoke affect the fetus through the placenta, leading to hypoxia in the uterus, rapid heartbeat and even death.

6. Avoid eating vegetables and fruits contaminated by pesticides: After pregnant women eat vegetables and fruits contaminated by pesticides, the normal gene control process turns or the fetal growth and development is delayed, resulting in congenital malformation; Serious can make the fetus stop developing and die, leading to abortion and premature delivery.

Seven taboos often drink strong tea: pregnant women often drink strong tea, which will have a negative impact on fetal bone development, and in severe cases, it will lead to fetal malformation.

Eight, avoid pickles: pregnant women often eat salty food, which will lead to sodium retention in the body, cause edema, and affect the normal development of the fetus.

Nine, avoid drinking alcohol: drinking alcohol in pregnant women will lead to intrauterine growth retardation, increase the rate of premature delivery and perinatal mortality.

Ten, avoid eating canned food: the chemical additives in canned food have little effect on healthy people, but sometimes have a great impact on pregnant women, which can affect the cell division of the fetus and cause developmental disorders.

................................................

Be prepared before pregnancy. Scientific pre-pregnancy preparation is the premise of eugenics, and the baby will be healthier and smarter.

In order to prevent neural tube malformation, folic acid should be supplemented in the first three months of pregnancy.

Prepregnancy nutritional supplement

Three months before pregnancy (from Chongqing Maternal and Child Health Network)

If you decide to get pregnant, you should be prepared three months before pregnancy.

◎ Choose the best season to conceive. February, March, July and August of the lunar calendar are the best seasons for conception.

Stop taking oral or implanted contraceptives. No x-rays, no drugs to treat viral infections or chronic diseases.

◎ Remove toxic substances, such as pesticides, lead, mercury, cadmium, anesthetics, etc.

Neither husband nor wife can smoke.

◎ Adjust your emotions. It is not suitable to get pregnant for a period of time after mental trauma or emotional fluctuation, such as wedding, loss of loved ones, accidents, etc.

Consult the obstetrics and gynecology department of a nearby hospital and take folic acid under the guidance of a doctor.

◎ Be prepared economically.

◎ Check whether the quality of your drinking water is qualified. Water pollution will affect the normal development of the fetus, so we must choose a suitable purification device.

◎ Remove smoke and toxic substances from husband and wife, and eat blood of livestock and poultry, spring leeks, sea fish and bean sprouts.

Two months before pregnancy (from Chongqing Maternal and Child Health Network)

◎ You can tidy up your living environment this month to facilitate your actions after pregnancy.

◎ Relocate things that may trip, leaving the largest space.

◎ Common articles should be placed where they can be easily taken when standing. Clean things under the bed and in the wardrobe, and adjust the position of kitchen utensils.

◎ Lower your clothes rack or clothesline appropriately and lengthen the light rope.

◎ Add anti-slip mats in places that are easy to slip, such as toilets.

Install handrails near the toilet to make it more convenient for you in the third trimester.

In addition, try to keep the working environment well ventilated.

◎ If your room is poorly ventilated, try to install a ventilator or make other improvements.

Get into the habit of putting things where they should be.

◎ Appropriate supplement of high-quality protein.

◎ Keep away from your dogs, cats, birds and other pets.

One month before pregnancy (from Chongqing Maternal and Child Health Network)

◎ You should adjust your dressing table this month, put the beauty products and cosmetics aside for the time being, and leave the skin care products. Because pregnant women only care for skin in principle, not beauty.

◎ Skin care products should choose well-known brands to prevent skin allergies from harming the fetus.

◎ TV, stereo, computer, microwave oven and mobile phone will all cause electromagnetic pollution, which is extremely unfavorable to fetal development. The "tire protector" protective cover that has been put on the market can effectively prevent magnetism. I suggest you buy a set in advance.

◎ Prepare at least one maternity dress and two pairs of flat-bottomed soft shoes.

◎ Don't choose the time of pregnancy when you are on a long business trip, tired and come back less than two weeks.

◎ Avoid getting pregnant on a full moon night to avoid giving birth to mentally retarded or deformed children.

Are you ready to be a mother?

With the development of society, the pace of life is getting faster and faster, and the pressure of social life is increasing. Many women value their careers more than motherhood. Pregnancy is not a happy thing for them, but more like an accident.

Scientific researchers have found that mothers who strongly want their children before pregnancy have a feeling of love for their children during childbirth. With the growth of children, in the constant communication and psychological communication with children, the love for children is also deepening. And those mothers who regard pregnancy as an accident and have a negative attitude towards pregnancy still don't feel the cuteness of their children three months after their birth. Later, with the passage of time and the increase of contact with children, maternal love gradually emerged and strengthened. But compared with those mothers who have strong feelings from the birth of their children, there is still a big gap in the intensity of their maternal love. The reason for this difference is that mothers have different attitudes towards the fetus before pregnancy. These two different attitudes not only lead to different degrees of care for the baby, but also have an impact on the fetus.

Mothers who want to have children before pregnancy will be very happy when they are pregnant and actively look forward to the birth of their children. Emotional stability during pregnancy, serious attitude towards pregnancy, can actively cooperate with health care during pregnancy and delivery. Under such circumstances, the fetus can develop healthily and give birth naturally. And psychologically unprepared mothers are negative and unstable during pregnancy. This kind of negative emotion will cause abnormal activity of autonomic nervous system and endocrine changes at the same time. Bioactive substances produced by endocrine changes enter the fetus through the placenta and umbilical cord, which has a negative impact on the fetus. In addition, due to poor health care during childbirth and relative lack of sufficient cooperation during childbirth, this often creates obstacles to childbirth.

It can be seen that before pregnancy, it is necessary to cultivate love for children, take a positive attitude towards delivery, and make psychological preparations, so that pregnant women can maintain a good psychological state during pregnancy, overcome the physical discomfort caused by pregnancy, and ensure the health of the fetus. We can establish the affection between mother and child as soon as possible, take care of the baby to the maximum extent, so that breastfeeding can be strongly guaranteed and the baby can grow up healthily.

How does the husband create conditions for eugenics?

It is the hope and responsibility of every family to have a good child, and the responsibility of a good child falls on young couples. For husbands, the quantity and quality of sperm are the key elements of eugenics, so sperm is called the basis of eugenics. Therefore, the husband should try to eliminate all factors that affect sperm quality; Husbands should actively create any conditions conducive to eugenics.

(1) Timely treatment of reproductive system diseases: In male reproductive organs, testis is the factory for producing sperm, epididymis is the warehouse for storing sperm, vas deferens is the transportation hub, spermatic artery and vein are the transportation lines for logistics supply, and prostatic fluid is the necessary lubricant for transporting sperm. When these key parts fail, eugenics will inevitably be affected. For example, people with bilateral cryptorchidism and congenital testicular hypoplasia cannot produce normal sperm. If inflammation, tuberculosis and tumor occur in testis, epididymis and seminal vesicle, leading to testicular atrophy and tissue destruction, most sperm are waste. Varicocele, prostatitis, partial defect of vas deferens, hypospadias, impotence, premature ejaculation and other diseases will make the wife infertile. There are also sexually transmitted diseases such as syphilis and gonorrhea, which will directly or indirectly affect the production, development and mobility of sperm and cause certain harm to fertility. Therefore, the husband must first treat reproductive organ diseases in time.

(2) Get rid of bad habits: Smoking, drinking and taking drugs not only affect your health, but also are the enemies of eugenics. People who smoke more than 10 cigarettes a day, the sperm activity decreases obviously, and with the increase of smoking, the sperm abnormality rate also increases obviously. Excessive drinking causes alcoholism, changes the morphology and activity of sperm, and even kills sperm, which will affect pregnancy and embryo development. To this end, foreign countries will be pregnant with deformed children because of husband and wife drinking in the same room on weekends, which is called "Sunday baby". According to some data, 60% of fetuses conceived after drinking alcohol are born with mental retardation. Under normal circumstances, it takes about 80 days for male spermatogonia to develop into mature sperm. Couples who are about to give birth to offspring must give up smoking and drinking during this time.

In recent years, the number of male smokers in China has increased year by year, resulting in perinatal deaths. It often leads to intrauterine growth retardation, premature delivery and fetal distress, and the incidence of mentally retarded children increases, which is harmful to family and society.

(3) Restrain sexual life: Frequent sexual life will inevitably make semen scarce, and the quantity and quality of sperm will also decrease accordingly. In order to ensure the normal birth of a new life, it is necessary for both husband and wife to abstain from sex, especially for the man, and more importantly, to conserve energy. This point, especially for newly married couples with strong sexual desire, should be paid more attention to.

(4) Avoid contact with harmful substances: Scientific research shows that many physical, chemical and biological factors act on the human body, which will damage the reproductive function, make chromosomes abnormal and sperm abnormal, and affect the normal pregnancy of the fetus. Contact with lead, benzene, xylene, gasoline, vinyl chloride and other substances, radioactive substances such as X-rays, pesticides, herbicides, anesthetics, etc. It will lead to fetal chromosome abnormality and increase the abortion rate.

(5) Use drugs with caution: The bitter taste of good medicine is beneficial to diseases, and some drugs can also damage reproductive function while treating diseases, resulting in fetal congenital malformation, such as morphine, metronidazole, streptomycin, erythromycin, mitomycin and cyclophosphamide, which have adverse effects on sperm. When taking drugs that damage sperm for treatment, we must avoid the birth of new life so as not to cause lifelong regret.

Which women are temporarily unsuitable for pregnancy?

In order to ensure children's health and achieve prenatal and postnatal care, the woman suffers from heart disease, hepatitis, nephritis, tuberculosis, diabetes, hyperthyroidism, asthma, epilepsy and other diseases. If it is acute, it must be actively treated, and it is not suitable for pregnancy for the time being. After the disease is controlled, she will get pregnant when her physical condition is competent for the burden of pregnancy or is not contagious, which not only protects her mother's health, but also avoids the abnormal development of the fetus caused by the disease or drugs. In addition, women with vaginitis should not get pregnant before they are cured.

Women with some benign tumors, such as abdominal cavity, pelvic cavity, breast, thyroid and other parts, should be operated or treated with drugs before pregnancy, so as to avoid the aggravation of diseases during pregnancy and difficult to deal with. Other abdominal diseases, such as subacute or chronic appendicitis, should also be treated before pregnancy to avoid anesthesia and medication difficulties during pregnancy, and to avoid affecting fetal development or causing abortion.

For women with the above diseases, if their condition improves or recovers after treatment, they should seek medical advice in time and choose the right time to conceive.

In addition, people who have a history of contact with acute infectious diseases, especially those who can infect the fetus through the placenta, such as children with rubella virus or patients with acute infectious hepatitis B, mumps and measles. Should be checked before pregnancy.

Pregnancy should not only consider health status, but also consider environmental factors. Some people have long-term exposure to substances harmful to the fetus, and some people have long-term use of certain drugs or long-term exposure to certain chemicals for professional reasons, which will affect the development of eggs, so pregnancy should be suspended.

At what age are children born to parents the smartest?

On the issue of marriage, people are most concerned about emotion; On the issue of fertility, the focus of scientists is heredity.

The research results of French geneticist Maurice 1989 show that the offspring of men aged 30-35 are the best. Morris said that male sperm quality peaked at the age of 30, and then it can last for five years. On the other hand, physiologists recognize that women between the ages of 23 and 30 are the best age to give birth. During this period, the overall development of women is fully mature and the quality of eggs is high. If pregnant, women have fewer complications, less risk of delivery, better fetal growth and development, and the lowest incidence of premature delivery, deformed children and dementia. At this time, both husband and wife are rich in life experience, energetic and capable of raising infants. If pregnant and premature, the fetus will compete with the developing mother for nutrition, which is unfavorable to the health of the mother and the development of the fetus. Therefore, it is not difficult to see that the best age combination for male and female children should be that the former is about 7 years older than the latter.

In recent years, relevant scholars have found that some "prodigies" may be related to the "big age difference" between their parents. For example, the father of Tchaikovsky, a great Russian composer, is 18 years older than his mother, and the parents of Madame Curie, a scientist, are 14 years older. The researchers' explanation for this phenomenon is that the father is older, his intelligence is relatively mature, and more "passwords" are passed on to the next generation, while the mother is younger and energetic, which will create a better reproductive environment for the fetus and is conducive to the development and growth of the fetus, so the offspring born in this "optimized combination" are prone to "genius".

Is eugenics related to the timing of conception?

The cultivation of talents does not start from school, nor from birth, but from the fetal period and even from fertilization.

A good mental state will have a beneficial effect on the reproductive cells of men and women. Therefore, when planning pregnancy, we should not only pay attention to the health of both men and women, but also choose the time with the best physical condition, the most energetic and the best mood, because the fertilized eggs obtained at this time are also of the best quality.

Active eugenics, also known as evolutionary eugenics, aims to promote the reproduction of excellent individuals intellectually and physically. Eugenics begins with the combination of eggs and sperm, which is related to how to choose the best time to conceive. The ancients said, "A good night's sleep will make the husband and wife feel peaceful and comfortable, and future generations will not only live long, but also have wisdom." Therefore, there is a saying that "the depth of love is the beauty of a baby". It is believed that when sleeping together, the environment is quiet and comfortable, the mood is comfortable, the feelings of both sides are deep and the relationship is harmonious, then the qi and blood are smooth and the essence and blood are abundant. When you are pregnant at this time, you can give birth to an individual with extraordinary wisdom and long life. "When men and women are in love, they communicate with each other, then do it, and then the yin and yang are reconciled and the essence and blood are condensed." It is emphasized that there should be "pre-bed play" before sexual intercourse to arouse sexual excitement, such as language exchange, skin contact, kissing, hugging and touching, which makes the sexual curves of men and women tend to overlap, greatly arousing strong desires, making both men and women synchronous and high-profile and reaching a wonderful realm. This is the so-called "spiritual communication". Only in this way can excellent offspring be born. On the other hand, it will be harmful if the husband and wife have sexual intercourse without induction.

Chinese medicine believes that people correspond to heaven and earth, and pay great attention to the environment of sexual intercourse, such as the cold and hot climate, the moments of lightning and thunder, noisy and lively voices and depressed mood, which should be avoided. The study of modern endocrinology has found scientific arguments for the timing of conception and eugenics. Recently, the National Institute of Mental Health published its research results. It is believed that the germination of love between men and women is related to vasopressin and oxytocin secreted by the posterior pituitary gland. In the process of intimate bedtime play, both men and women secrete a large amount of vasopressin and oxytocin, which together with sex hormones known in the past constitute an internal environment conducive to reproduction, making ovulation, ejaculation, fertilization, implantation and other links conform to physiological characteristics. The coordination of endocrine hormones and the stability of internal environment will undoubtedly make the fetus develop well and become an individual with good intelligence and physical strength. If the sexual environment is not good, you are in a bad mood, or you suddenly have sex without sex before going to bed, the secretion of sex hormones, vasopressin and oxytocin will inevitably be low, which will not only cause mental pain, but also make you pregnant at this time. All kinds of conditions are not available, and the internal environment is bad, which will inevitably affect the development of the fetus.

It can be seen that the timing of conception is closely related to eugenics, and all links are indispensable in order to cultivate an excellent talent.

Is biological rhythm helpful to eugenics?

Biological rhythm (also known as biological clock) refers to the law that organisms make periodic changes with time. From birth to the end of life, there is a high and low period of biological rhythm every month. When a person is at the climax of the biological clock, he is energetic, open-minded and cheerful, showing great creativity and rich artistic appeal. He also has a flexible mind, quick thinking, strong memory and stronger logic than usual. At the low tide of biological rhythm, the human body is prone to physical fatigue, sloppy, irritable, capricious, slow thinking, inattention, forgetfulness and poor judgment. The critical period is between the high tide period and the low tide period, which is an extremely unstable period. Poor coordination in all aspects of the body is prone to diseases, mistakes and accidents.

The biological clock cycle that restricts people's emotions is 28 days, that restricts people's physical strength is 23 days and that restricts people's intelligence is 33 days. These three biological clocks of human beings are closely related. When people's three biological clocks are above the periodic line, they will be full of energy and high intelligence, which is the most ideal state.

Healthy men and women can give birth to a child with excellent health and intelligence if they conceive at the climax of biological rhythm. If one party is at the climax and the other is at the low tide, then the child's innate quality and intelligence are average. If both parties have sex and get pregnant at low tide, the child may be physically and mentally poor. We often see in life that although parents are smart, their crystallization is stupid and dull. On the contrary, the "Chinese-funded" couple gave birth to an excellent child.

What career positions do women need to change before pregnancy?

With the continuous development of society, more and more women have joined all walks of life and become professional women. Some women's working environment contains high concentrations of chemicals, which affects women's reproductive function and the healthy development of the fetus. Therefore, in order to improve the quality of the population and achieve prenatal and postnatal care, women in some professional positions should temporarily change jobs when considering pregnancy. Some toxic substances can remain in the body for more than a year. Even if you leave this kind of post, you should not get pregnant immediately, otherwise it will easily cause teratogenesis, and appropriate measures should be taken to avoid it. It is found that fertilized eggs, implanted blastocysts and early embryos may have been invaded after pregnancy, and it is too late to take protective measures. Women engaged in the following occupations should be transferred from their posts:

Some special jobs: Frequent exposure to lead, cadmium, mercury and other metals will increase the possibility of miscarriage and stillbirth of pregnant women, among which methyl mercury can cause teratogenesis and lead can lead to mental retardation of infants; Organic substances such as carbon disulfide, xylene, benzene and gasoline can cause abortion.
