First, the incidence of spontaneous abortion has increased.
Older women are usually more prone to chromosome abnormalities, so the incidence of spontaneous abortion in early pregnancy is greatly increased. Studies have shown that the abortion rate of older women in early pregnancy is as high as 20%, which is 2 to 4 times that of school-age pregnant women.
Second, the incidence of premature delivery has increased.
Compared with school-age women, the intrauterine environment of elderly pregnant mothers is relatively poor, which is not conducive to the growth and development of the baby. Therefore, in the third trimester of pregnancy, abnormalities are prone to occur, forcing the baby to be born early. According to some data, the premature delivery rate of elderly women is four times that of women of childbearing age.
Third, the incidence of infertility has increased.
A report shows that a woman's ability to conceive will decrease obviously with her age. The pregnancy rate is about 74% before 3 1 year old, 60% after 3 1-35 years old, and only about 53% after 35 years old. It can be seen that the incidence of infertility increased significantly after the age of 35.
Fourth, the incidence of dystocia has increased.
When women are too old, the joints of cervix, perineum and pelvis will become hard, which also leads to difficulties in expansion during delivery, and the contractility of uterus and the tension of vagina are also poor, which leads to slow delivery and prolonged delivery time.
Generally speaking, after the age of 35, the function of the whole body organs and tissues began to decline. After giving birth to a child, it is not only prone to various postpartum diseases, but also the recovery ability of reproductive organs will be weakened. Studies have shown that the older you are at delivery, the slower your body will recover after delivery. Therefore, as a woman, we should get married and have children as soon as possible, preferably between the ages of 23 and 30.
