Wei Zi's reproductive age

The best childbearing age is between 25 and 30 years old.

China women's body organs and systems will not mature until they are 24-25 years old. If they give birth prematurely, for example, before the age of 20, the incidence of dystocia and complications during pregnancy and delivery will increase accordingly, and the incidence of miscarriage, premature delivery and fetal malformation will also be high. However, it is not good to be born too late. If the first child is born at the age of 35, it is an elderly primipara, and the dystocia rate is obviously improved, which is not good for both mother and baby, and it is easy to affect the quality of newborns.

If the childbearing age is too late, the rate of fetal malformation will increase after conception, and the incidence of dementia will increase with the increase of maternal childbearing age. This is because the eggs of elderly women are gradually aging under the influence of various environmental factors. In the process of egg meiosis, chromosome separation is easy to occur, which leads to abnormal chromosome number of eggs.
