What do you know about the five knowledge of prenatal eugenics? In life, many women will make corresponding preparations before pregnancy, which is also called eugenics. A gifted baby will be healthier and better. Here I have compiled five pre-pregnancy eugenics knowledge. Let's have a look.
Five knowledge of prenatal eugenics 1 1, to ensure adequate heat supply.
Newlyweds should increase their nutrition half a month before they are ready to have children.
A light manual worker should increase the intake of 400- 1000 kilocalories on the basis of supplying 2600 kilocalories for sexual consumption every day, and at the same time save some calories for pregnancy and create necessary conditions for prenatal and postnatal care.
2, add enough protein.
Protein is the basic raw material of sperm and eggs, which is very important to improve the quantity and quality of male sperm and semen, enhance the vitality of sperm and improve the pregnancy rate. Protein of sperm contains more arginine, which must be taken from food. When arginine is consumed in large quantities, it should be replenished in time.
Step 3 eat the right amount of fat
Fat is the high thermal energy of human body, and the essential fatty acids contained in fat are indispensable substances that constitute human cells and tissues. Fat can promote the growth and maturity of women and maintain menstruation and fertility. Nutritionists estimate that when fat accounts for 22% of body weight, normal menstruation can be maintained, which is beneficial to ovulation, pregnancy, childbirth and breastfeeding. Therefore, young women must not neglect the necessary fat intake in pursuit of slimness.
4, meet the needs of inorganic salts and trace elements
Inorganic salts are the main raw materials for bones and muscles, and also important substances for regulating physiological functions. Trace elements such as iron, zinc and copper are also important substances for hematopoiesis, hair care and intelligence improvement. Zinc can increase the level of blood sex hormones and sperm count, and promote gonadal secretion. If zinc is deficient, men will suffer from sexual dysfunction, impotence and premature ejaculation, the number of sperm will drop by 30% ~ 40%, and even lose their fertility. Women will catch cold and amenorrhea, which will not only affect the sexual life of husband and wife, but also lead to female infertility, abnormal fetal development, chromosome aberration, fetal malformation and abortion. Insufficient copper intake in women will affect the growth and maturity of follicles, inhibit the peristalsis of fallopian tubes, which is not conducive to the operation of eggs and leads to infertility.
5. Take enough vitamins.
B vitamins, vitamin C, vitamin E and vitamin D play an important role in the growth and development of sexual organs, spermatogenesis and ovulation, reproductive pregnancy and the metabolism of various nutrients. For example, vitamin E can enhance sperm motility and promote sexual desire of men and women. Many studies have confirmed that men with sufficient vitamin C in their bodies will have healthier sperm. The more vitamins men take, the stronger their ability to prevent DNA from being destroyed, especially for smokers. Therefore, both husband and wife should supplement foods containing the above vitamins.
Five knowledge of pre-pregnancy eugenics and two taboos of pre-pregnancy eugenics
1, don't get pregnant if you are depressed.
Once people are in a mental state of anxiety, depression and heavy mental burden, their physiological functions will inevitably change, which will not only affect the quality of sperm or eggs, but also affect the hormone secretion of the mother and the growth and development of the fetus due to emotional stimulation after conception. Therefore, when unpleasant things happen in small families, it is best to use temporary contraception.
2. Don't get pregnant if you are overtired.
For example, during the honeymoon period and the journey, both men and women are on the run, rushing about for the etiquette and entertainment before and after the wedding, welcoming and sending, physical overload, reducing the quality of sperm and eggs. Frequent sexual life during the honeymoon will also affect the environment in which sperm and eggs are implanted in the uterus, which is not conducive to eugenics. However, people's daily life in travel is irregular, and their brains are often in a state of excitement. Coupled with excessive fatigue and bumpy journey, it may affect the growth of pregnant eggs or cause uterine contraction, leading to abortion or threatened abortion. Therefore, it is best not to get pregnant when you are tired.
Don't get pregnant during illness.
Because the disease affects the constitution, the quality of fertilized eggs and the intrauterine implantation environment, the drugs taken during the disease may have adverse effects on sperm and eggs, leading to defects in newborns. Therefore, when the husband and wife are sick, they have to wait until they recover and stop taking drugs for more than half a year before they can get pregnant.
4. Don't get pregnant at an advanced age
Men over 55 years old and women over 35 years old are called late pregnancy, so it is necessary to strengthen monitoring during pregnancy, because the incidence of fetal malformation in late pregnant women is relatively high.
5. Do not contact radioactive substances and highly toxic substances before pregnancy.
Because germ cells are very sensitive to X-rays and highly toxic substances. If a woman receives X-rays before pregnancy, especially after abdominal X-rays, it is safer to wait for 4 weeks before pregnancy.
6, early winter to early spring is not suitable for pregnancy.
Because early pregnancy is most afraid of virus infection, once pregnant women are infected with the virus, the teratoma rate will increase significantly, and winter and spring are the frequent seasons for virus transmission, so early winter to early spring is not suitable for pregnancy.
7. Don't smoke and drink before pregnancy.
Nicotine in cigarettes and ethanol in wine can damage sperm cells and egg cells. Women who smoke and drink regularly had better wait for 2-3 months to quit smoking and drinking before getting pregnant. It is best for a husband to give up smoking and drinking 1 month before his wife becomes pregnant.
8. Don't keep pets such as cats and dogs before pregnancy.
Pets such as cats and dogs may infect women with various germs, such as Toxoplasma gondii infection, which can directly infect the fetus and make the fetus deformed. So don't keep cats, dogs and other pets before pregnancy.
9. Don't get pregnant immediately after stopping using birth control pills.
You can get pregnant at least 3 months after stopping the drug, and it is best to get pregnant after stopping the drug for half a year; Women who have placed intrauterine devices should wait for 2 ~ 3 normal menstrual cycles before getting pregnant, which can make the endometrium and ovulation function have a process of recovery and adaptation, which is conducive to the growth and development of fertilized eggs.
10, don't get pregnant immediately after premature delivery, abortion and hydatidiform mole curettage.
Women suffer from endometrial damage after premature delivery and abortion. If you get pregnant immediately, it is easy to have repeated abortions and form habitual abortions. Therefore, at least half a year after the first abortion or premature delivery, you need to get pregnant. After surgical treatment of hydatidiform mole, after a period of time (mostly 1 ~ 2 years), the trophoblast cells originally hidden in venous plexus can become active again and even become malignant. Therefore, for postoperative patients with hydatidiform mole, in order to prevent them from developing into malignant hydatidiform mole or choriocarcinoma, they should be followed up regularly for at least 2 years, during which they cannot get pregnant.
