How many years old is the smartest child?
When it comes to fertility, scientists focus on genetics. French geneticist Morris's research results show that men aged 30-35 have the best offspring.
Morris said that men's sperm quality peaks at the age of 30, and then can last five years of high quality.
Physiologists, on the other hand, agree that women between 23 and 30 are the best age to have children.
During this period, the whole body of women is fully mature, the quality of eggs is high, if pregnant, the risk of childbirth is small, the fetal growth is good, the incidence of premature birth, malformation and dementia is the lowest. In this age group, the husband and wife are rich in life experience, energetic and have the ability to nurture infants. If women get pregnant and give birth too early, the fetus will compete with the developing mother for nutrition, which is not good for the mother's health and fetal development.
It is not difficult to see that the optimal age combination of male and female fertility should be that the former is about 7 years older than the latter. The father is older, the intelligence is relatively mature, and the 'code' passed on to the next generation is more; the mother is young and vigorous, which will create a better breeding environment for the fetus, which is conducive to the development and growth of the fetus. Therefore, the offspring of this' optimized combination 'are prone to' genius'.

The basic skills of birth inspection should not be ignored
Due to the development of science, medical diagnostic equipment and technological progress, the risk of pregnancy and childbirth of women is much less than in the past. However, prenatal examination can not be ignored!
The perfect prenatal examination can find out the abnormality of pregnant women and fetus as soon as possible, grasp the appropriate treatment opportunity, and do a good job of health control for fetus and expectant mother.
At the first prenatal examination, the hospital or clinic will issue a "health manual for pregnant women". The medical staff will record the examination results in the manual in detail. Generally speaking, the number of complete prenatal examination is 15.
Every 4 weeks before 28 weeks of pregnancy, every 2 weeks from 29 to 36 weeks of pregnancy, and every week after 37 weeks of pregnancy. High risk pregnancy or pregnancy complications of pregnant women, depending on the situation to increase the number of examinations.
Over 34 years old is a high risk group for Down's syndrome
It should be noted that not every pregnant woman needs to receive the above examinations; only when the probability of her fetus having congenital abnormalities is greater than the incidence of complications of amniocentesis, it is worth receiving these examinations.
If you just want to predict the sex of the fetus, it does not meet the original purpose of the examination. Before sampling, pregnant women also need to fully understand the purpose, safety, success rate and complications of each examination, so as to remove unnecessary psychological barriers.
The new development of prenatal genetic diagnosis allows pregnant women to have more and better choices, and the health of the fetus must rely on the careful care and attention of the mother, in order to lay a good start for the health of the baby. It is expected that every parent can enjoy the joy of being a parent, and every baby is the child expected by parents.
