giving birth to a child by an old woman is a struggle on the line of life and death, which is of great danger. Medically, a pregnancy over the age of 35 can be called an 'advanced pregnancy'. Studies have shown that the incidence of various diseases in older pregnancies has increased by two to four times compared with women in age appropriate pregnancies.
From the point of view of women's physiological law, the most powerful fertility is at the age of 25. After the age of 30, it begins to decline slowly. After the age of 35, it declines rapidly. After the age of 44, 87% of women have lost the ability to conceive and the risk factors associated with pregnancy are also increasing.
1. Increased rate of spontaneous abortion
The chromosomal abnormalities of elderly women are easy to occur, so the incidence of spontaneous abortion in early pregnancy is greatly increased. The data shows that the abortion rate in the first trimester of the elderly pregnancy can be as high as 20% in the early stage of pregnancy, which is 2-4 times of that of the pregnant women of the right age.

2. The rate of premature birth increases
The uterine environment of the elderly pregnant women is relatively poor, which is not conducive to the growth and development of the fetus. It is easy to occur abnormalities in the late pregnancy, so that the fetus is born early. The data shows that the premature delivery rate of the elderly pregnancy is 4 times higher than that of the age-appropriate childbearing women.
3. Increased dystocia rate
When women are too old, the joints of cervix, perineum and pelvis become hard, and it is not easy to expand during delivery. The contractile force of uterus and the stretching tension of vagina are also poor, which results in slow delivery speed, prolonged delivery time, and dystocia.
4. Breast cancer rate increases
According to the research data, the incidence of breast cancer in women who have given birth for the first time above 35 years old is much higher than that before 30 years old, and the older the women are, the higher the incidence is.
5. Increased incidence of infertility
The incidence of infertility will increase significantly later than the age of 35. This is mainly the result of physiological and endocrine changes in the body.

6. Increased incidence of congenital dementia
After the age of 35, the maturation of eggs is prolonged, and chromosomes are prone to aging, degeneration or distortion, which leads to the increase of incidence of congenital dementia. The data shows that the incidence of congenital dementia is only 1:1350 in 25-34-year-old pregnant women, and 1:260 in 35-39-year-old pregnant women.
7. High blood pressure and diabetes during pregnancy
With the increase of age, the risk of hypertension, diabetes and other diseases increases. As a result, the incidence of these diseases during pregnancy will increase as the metabolism of the body changes after pregnancy. The data shows that the incidence of pregnancy hypertension in the elderly pregnant women is 2-4 times higher than that of the age-appropriate pregnant women, and the incidence of diabetes mellitus and pregnancy diabetes is more than 3 times higher than that of the 25-29-year-old pregnant women.
8. Slow recovery after childbirth
After the age of 35, the function of organs and tissues began to decline. After childbirth, it is not only easy to have various postpartum diseases, but also the adjustment of endocrine to the body and the recovery ability of reproductive organs will be weakened. The data shows that the older the delivery, the slower the recovery rate.
9. The baby is weak
After the age of 35, women's body function began to decline. The pregnant ability of the uterus and the ability to provide nutrition for the fetus were worse than those of pregnant women. The data shows that the immunity of the children born to the elderly pregnant women, especially the first child, is relatively weak, and the incidence of various diseases increases, such as leukemia.
10. Poor mental state
The psychological burden of pregnant women over 35 years old is higher than that of pregnant women at the right age. In addition, social and family pressures tend to make the spirit in a state of tension, which is not conducive to their own health and the growth and development of the fetus.
