In the process of pregnancy, childbirth, childbirth and child-rearing, for a woman, 25 to 30 years old is the most ideal time to give birth, and if it is the first child, it should not be over 30 years old at the latest.
Premature childbirth for women is not only detrimental to their physical and mental health, affecting their study, work and physical health, but it may also lead to more dangerous things happening. Early pregnancy increases maternal mortality. The maternal mortality rate for those under 20 years old is as high as 8.6‰. Infant mortality rates are also higher among women who are pregnant early.
The incidence rate of cervical cancer among those who marry early is 3 to 7 times higher than that among those who marry later. Especially for those who give birth before the age of 18, it can be 20 times higher. For those who give birth to their first child under the age of 20, the incidence rate of cervical cancer is 3 to 7 times higher than that of those who marry later. The incidence rate is seven times higher than that of those over 25 years old who have their first child.
We must realize that the older women of childbearing age are, the easier it is for the eggs in the ovaries to age. The longer the eggs are stored in the ovaries, the greater the chance of receiving harmful factors such as infection and radioactivity, which will increase the number of chromosomes. The chance of mutations leading to fetal malformations.
Pregnant women over 35 years old are medically defined as elderly pregnant women.
Now, with the advancement of social civilization, increasingly fierce social competition, accelerated pace of life, and updates of people’s ideas, there are more and more elderly pregnant women. \”Life Times\” recently reported that it has become more difficult to get pregnant at the age of 35. At the Fourth Annual Academic Conference on Reproductive Medicine of the Chinese Medical Association held in Nanning, Guangxi recently, relevant experts introduced that the results of some small-scale fertility studies in the past 30 years showed that in my country, The fertility of couples of childbearing age has declined significantly, but there is no relevant data nationwide.
Experts say that starting from the age of 35, the quality of female egg chromosomes declines significantly. By the age of about 40, the ratio of normal chromosomes in eggs is less than 50%, which can cause infertility and miscarriage, and can also cause infant deformity. The risk of miscarriage over the age of 45 has exceeded 50%, and the probability of genetic mutations in eggs reaches 23%. Therefore, it is best for women to complete childbirth before the age of 35, not too late.
The husband’s age will affect fertility
As age continues to increase, men’s fertility gradually declines. Studies have shown that when a woman becomes pregnant when she is over 35 years old or when a man is over 40 years old, the chance of the fetus having chromosomal abnormalities increases significantly. If the husband is over 55 years old, the probability of his wife developing Down syndrome is twice as high as that of younger men..
