Why should we encourage late marriage and late childbearing?

China's marriage law stipulates that men can only get married when they are 22 years old and women can only get married when they are 20 years old, but this is the legal minimum age for marriage, not the advocated age for marriage.

With the progress of the times, the renewal of people's concepts and the improvement of living standards, there is a trend that the marriage age of men and women is gradually delayed in all countries of the world. People's sexual behavior is gradually developing in a scientific direction, which is consistent with people's physiological functions.

At the end of adolescence, men reach 20 years old and women reach 18 years old, and their sexual development is close to maturity. From this perspective, they have the conditions to get married and have children. But a person's sexual maturity does not mean that all organs in the body are mature. Physiologically, gonads, genitals, heart, kidneys and other important organs generally do not fully mature until the age of 23-25. If you get married too early, it will have a negative impact on women's health and fetal development. Because bones can't be completely calcified until after the age of 23, young women need enough nutrition to continue to promote bone development. If pregnant, the fetus needs a lot of nutrition from the mother. This will not only affect the mother's own development, but also have a direct impact on the development and health of the fetus.

According to statistics, most scientists and writers are around the age of 30, even reaching their peak. Famous scientists and writers all over the world cherish their golden age. In order to make full use of this wonderful time and engage in scientific activities and literary creation, they all consciously married late. For example, Carl von Linnaeus, a Swedish plant taxonomist and "plant king", got married at the age of 32. Curie, physicist and "father of radium", got married at the age of 38. Italian atomic physicist, Nobel Prize winner Frye and Danish atomic physicist niels bohr both got married at the age of 27. Rutherford, a famous nuclear physicist in New Zealand and a Nobel Prize winner, got married at the age of 30. Therefore, young people should cherish their "golden age", consciously marry late, and let the most precious years of life spend in the flash.

From the aspects of pathology, obstetrics and gynecology, the incidence of dystocia, pregnancy-induced hypertension syndrome and premature delivery in early married women is relatively high. Data show that the incidence of cervical cancer in women who marry early is several times higher than that in women who marry late. This is obviously not conducive to women's physical and mental health.

As far as society is concerned, early marriage and childbearing will also bring population problems. It can be calculated that if you get married and have children at the age of 20, 100 has five generations; If you get married and have children at the age of 25, 100 will have only four generations, a whole generation less population. Therefore, advocating late marriage can control population growth.

Of course, advocating late marriage and late childbearing does not mean that the later you get married and have children, the better. Generally speaking, women's reproductive age should not exceed 30, especially 35. If you get older, the chances of dystocia and congenital stupidity will increase greatly. Therefore, from the perspective of prenatal and postnatal care, best age for marriage for men is 25-27 years old and best age for marriage for women is 23-25 years old.
