Five factors that hinder eugenics

The five factors that hinder prenatal and postnatal care, excellent pregnancy, are to conceive and have children at the right age and the best opportunity, and to avoid the unfavorable factors of fetal dysplasia as much as possible. Here are five factors that hinder eugenics!

The five factors that hinder eugenics are 1 1, when receiving a lot of radiation.

Low dose radiation (200-300 roentgen) can cause a large number of sperm abnormalities or azoospermia, and high dose radiation (600-800 roentgen) can cause infertility;

For women, the dose of 200 roentgen can cause temporary menopause, and 500-800 roentgen can produce permanent ovariectomy (the radiation dose of a chest X-ray is about 0.3 roentgen); Therefore, sexual life or contraception should be avoided during the period of receiving a lot of radiation due to occupational or therapeutic needs.

2. Smoking.

Male smoking will reduce the number and activity of sperm; Female smoking or passive smoking can affect the quality of eggs, tar has anti-estrogen effect, may affect pregnancy, and may lead to ectopic pregnancy due to tubal peristalsis. Pregnant women smoke passively 1 hour, which is equivalent to smoking 4 cigarettes by themselves.

Cyanide in smoke reacts with sulfur-containing amino acids in the body, which can consume vitamin B 12, leading to fetal cleft lip, cleft palate, neural tube malformation, mental retardation and so on.

3. Take diet pills.

Some chemical poisons, drugs or harmful substances may cause sperm and eggs to mutate, thus causing fetal malformation. Therefore, in order to give birth to a healthy baby, both husband and wife who plan to get pregnant should not lose weight even 1 year before they start planning to get pregnant.

4. drink.

Long-term alcoholism in men will affect sperm development. Pregnant women who do not contain alcohol should pay attention to the use of various alcoholic beverages to avoid unintentional intake.

Drinking two glasses of wine a day may give birth to a low birth weight baby, and four glasses may cause mild deformity. Alcoholic women 1/3- 1/2 will have serious problems: less brain cells, poor hand-eye coordination, poor fine movements, mental retardation, easy crying in infancy, hyperactivity in childhood, mild to moderate microcephaly, small eye fissure and short nose;

Abnormal skeletal joints may include microcephaly, cleft lip and palate, short neck and webbed neck.

5. Drink coffee.

Coffee does not increase the risk of congenital malformation, but the more you drink, the lower the birth weight of newborns.

Five factors hinder eugenics, and two or four factors will affect eugenics.

1, environmental pollution affects prenatal and postnatal care.

The air, water quality, soil and food are polluted by toxic substances, which destroy the balance of human body, affect the genetic structure of parents' somatic cells and germ cells, have an impact on fetal health, and even cause abortion, fetal malformation and hereditary diseases.

2. The malpractice in the workplace affects eugenics.

Experts say that bad working environment and sedentary working style do great harm to women, and lack of exercise is also one of the factors affecting prenatal and postnatal care.

Women sit and work for a long time and have little activity, which affects blood circulation. The oppression of pelvis forces poor blood circulation in uterus, which hurts the mother and affects the baby's health. For pregnant women, it is particularly important to make the body move during work.

3. Drug abuse affects prenatal and postpartum care.

Among the birth defects of newborns, 2 ~ 3% may be caused by drugs. Most drugs that are harmful to the fetus are taken without knowing the pregnancy, especially the pregnancy reaction in the first trimester is regarded as a disease, and many drugs are taken unintentionally.

Generally speaking, taking medicine occurs within 3 weeks of pregnancy, which is called safety period. If there is no sign of miscarriage, it means that the drug has no effect on the embryo and the pregnancy can continue.

4. Alcohol and tobacco affect eugenics.

Smoking will have a negative impact on the development of fetal intelligence and cardiovascular system. Couples who are going to get pregnant, it is best to quit smoking 6 months before pregnancy. Alcohol can cause fetal alcoholism syndrome, which is characterized by small head, mental retardation and developmental retardation. It is suggested that both husband and wife should be prepared to give up drinking three months or six months before pregnancy.

How to determine the best pregnancy time for prenatal and postnatal care

1. Both husband and wife are in a good psychological state, especially mentally comfortable, without any worries. When both sides have no diseases, women who take oral contraceptives for a long time should stop taking them for two months before getting pregnant. Three months before conception, it is best for both men and women not to drink and smoke, and to have a good nutritional status.

2. Choose the pregnancy season, get pregnant in July and August, and give birth in April and May. Within one month before conception, the number of sexual intercourse should not be too frequent. According to the woman's ovulation period, it is best to succeed once. When both parties have strong sexual needs.

3, the same room time should be chosen before getting up in the morning, not before going to bed at night, because it is tired at night, and after resting in the morning, it is full of energy. Moreover, it is easy for women to measure ovulation period in the morning, and the level of androgen is high.

4. Catch up with sunny days. Don't watch horror movies during pregnancy, and walk in beautiful natural environment.

Five skills of creating eugenics.

1, neither too fat nor too thin.

Obesity may not only endanger health, but also cause excessive hormone secretion, thus hindering the whole ovulation process. This may make your ovulation cycle disorder and reduce the chances of pregnancy.

On the other hand, if the body is too thin, it will reduce the secretion of hormones and hinder the ovulation process. If you are pregnant, insufficient hormone secretion will easily lead to abortion.

Physical exercise is good for keeping healthy. But gynecologists pointed out that don't exercise too much. High-intensity physical exercise (such as long-distance running or fierce competition) will stop ovulation or shorten ovulation cycle. Excessive exercise can also increase the risk of miscarriage.

2. improve your diet

Ensuring good nutrition can increase the chances of pregnancy. You should supplement enough protein, iron, zinc and vitamin C. When the human body lacks these nutrients, it will prolong the menstrual cycle, make pregnancy more difficult and increase the chances of early abortion.

Taking nutritional medicine supplemented with multivitamins is the easiest way to obtain vitamins and trace elements such as zinc.

Your diet should also include foods rich in protein, such as meat, fish, low-fat dairy products, eggs and beans. Vegetarians can eat a variety of foods containing protein together, such as rice and beans, or fried tofu, which can fully supplement amino acids.

3. Quit smoking first, then get pregnant.

You can think of pregnancy as another reason to quit smoking: gynecologists point out that the toxins in cigarettes not only harm eggs, but also lead to ovarian aging.

The results show that the ovarian function of 35-year-old female smokers is almost the same as that of 42-year-old female nonsmokers, and smoking leads to the decline of female fertility. However, if you can quit smoking, some ovarian functions can still be restored.

This is a thin and soft bloody secretion with mucus in the cervix, which is pink or dark red. If the blood volume is low, you don't need to be admitted to the hospital, just continue to observe. According to statistics, labor pains will begin within one week after the red autumn.

4. Know your menstrual cycle.

Usually, women's menstrual cycle is 25-35 days. If your menstrual cycle is significantly longer than others, such as 42 days, then your ovulation times are less than others, and the chances of pregnancy are correspondingly reduced. At this time, you should see a doctor.

When preparing for pregnancy, it is necessary to find out your susceptible pregnancy, which generally refers to the ovulation period and 4-5 days before, during which you can have regular sexual life.

But don't take it for granted that you will ovulate every menstrual day 14. The ovulation period of different women varies greatly. For those who ovulate earlier, ovulation may start from the sixth day of menstrual period, while for those who ovulate later, it may wait until the second day1day.

5. release the pressure.

Stress and depression can affect your fertility. Women with high psychological pressure are less likely to get pregnant than others. Experts suspect that stress, like high-intensity physical exercise, will reduce the secretion of hormones in the body, thus causing menstrual cycle disorder.
