Giving birth to children and reproducing is the eternal theme of human beings for thousands of years, especially after coming to modern society, everyone has a deeper understanding of "eugenics and eugenics".
Many people have more or less understanding of women's reproductive age, knowing that women are too old, fertility and various functions of the body will decline, and due to the joint action of physical fitness, environment, society, psychology and other factors, the difficulty of pregnancy and fetal quality will be affected, and most of them have heard of the "elderly mother" saying.
But when it comes to men's "best age for childbearing", many people do not know anything, after all, some men are forty or fifty years old, and even sixty or seventy years old are still "old and have children", it seems that the age limit of childbearing only exists in women.
Nowadays, with the liberalization of the two-child and three-child policies, some men will be proud of their "sowing ability" without age restrictions, and they plan to "fight a fight" again, and want a second and third child.
As everyone knows, from the perspective of "eugenics and eugenics", men also have the best reproductive age, once it is exceeded, Bao Dad will try not to have a second child.
Why do men also have the "best age to have children"?
In feudal society, whether it is the sex of the fetus or the probability of pregnancy, everyone is accustomed to putting all the blame on women, which is very ignorant and unfair.
In fact, the task of giving birth to a life, the male task is not just a "seeding machine", in the whole stage of life conception, it is closely related to the quality of male fertility.
Stages of conception
Although according to medical statistics, the natural reproductive age of modern men can reach 90 years old, the quality of men's semen will gradually decline with age, and the quality of small tadpoles determines the difficulty of women's conception.
According to research data, men over the age of 40 are more than 30% less likely to conceive in 12 months than men under 30 years of age, while men aged 45 and over take five times as long as men under 25 years of age.
Therefore, if the man is too old, even if he has fertility, the probability of his wife's conception will be greatly reduced, and it will be easier to fail to prepare for pregnancy.
Stages of embryonic development
Since Bao Mom has successfully conceived the baby, is it possible that Bao Dad can do everything well and retire?
The answer, of course, is no, and modern medicine proves that the quality of embryonic development is closely related to the quality of small tadpoles in men.
With the increase of male age, the DNA integrity, point mutation, telomere length, chromosomal structure and other characteristics of the small tadpole will change, and these changes will increase the dominant mutations of autosomals, making the fetus prone to cartilage hypoplasia, Marfan syndrome and other diseases.
And with the increase in male age, the rate of DNA fragmentation of small tadpoles increases, the embryo stops developing, and the incidence of miscarriage will also increase greatly, it can be said that whether the baby can safely spend 10 months in the belly of the mother, the father will play a crucial role.
After the fetus is born
Studies in the British Medical Journal have shown that the older the father, the higher the risk of premature birth of the newborn, the lower the birth weight, and the lower the Apgar score.
In addition, there are a number of studies that show that the higher the age of male childbearing, the greater the probability of children developing schizophrenic diseases, and the earlier the symptoms appear, the data show that children born to men over 40 years old have a 4.75-fold increased risk of autism spectrum disorder.
Beyond this age, men have to work harder to give birth.
Although the medical community does not agree with the optimal reproductive age for men, from a comprehensive point of view, the reproductive quality of men within 25-35 years old is relatively high, and it should not exceed 40 years old at the latest.
Of course, this does not mean that men over 40 years old should never "fight for the second child", but it is recommended to make more efforts when preparing for pregnancy.
For example, accompany the wife to do some necessary physical examinations, especially the quality of the small tadpole, to determine whether it can meet the standard of life conception, and if the mother has a history of miscarriage in the past, or there is a repeated fetal stop, then the husband and wife also have to check the chromosomes to confirm whether there is a problem.
In addition, for the "elderly father", it is also important to maintain good living habits, many men have the habit of staying up late, smoking, drinking, these bad habits have a negative impact on semen quality.
At least the first 3 months before the preparation for pregnancy, men should pay attention to maintaining a regular work and rest time, exercise more, if necessary, you can also carry out some nutritional supplements in a purposeful manner under the guidance of a doctor.
Old Miao Conclusion:
The conception of life has never been just the responsibility of women themselves, and men also play a vital role.
If the majority of bao dads still have the intention of "fighting another child", then they should pay more attention, try to complete the task before the age of 40, and once they exceed the age of 40, they must be doubly careful in all aspects.
