Women’s egg cells age irreversibly with age. Studies have reported that the reserve function of the ovaries will decline rapidly after 33 years of age. At the same time, if you have experienced multiple miscarriages before the age of 35, it will increase the chance of infertility; after the age of 35, there are uterine fibroids, cervical erosion, endometriosis, breast tumors, ovarian cysts, premature ovarian failure, etc. During the high incidence of diseases, these diseases can easily cause infertility. The level of AMH (anti-Mullerian hormone) can be tested to assess ovarian reserve and prepare for pregnancy in time.

When a general woman is pregnant, there is a natural probability of 2% to 4% that fetal malformations will occur. But if the pregnant mother is older than 34 years old, the probability of fetal malformation will increase to 8% to 15%, which is 4 to 5 times that of normal pregnant mothers. Among them, the most common is that the probability of children with Down syndrome increases 7-10 times, which will cause a heavy economic and social burden on the family and even the entire society.

Due to low hormone levels, aging of body functions and decreased embryo quality, the risk of miscarriage and premature delivery for older pregnant mothers also increases.

Older pregnant mothers are more likely to suffer from gestational hypertension, preeclampsia, gestational diabetes, and preeclampsia. At the same time, due to physical aging, they are prone to chronic diseases such as hyperthyroidism, kidney and cardiovascular diseases, which will increase maternal health. Complications of the fetus.

Preeclampsia will not only cause serious adverse outcomes for pregnant mothers, such as kidney function damage, abnormal liver function, cerebral edema, blindness, heart failure and other diseases; but also cause premature birth, fetal intrauterine growth restriction, fetal distress, and other diseases. Stillbirth and so on. The detection of placental growth factor (PLGF) can be used to predict the prevention of preeclampsia.

The first child is a pregnant mother with a cesarean section, and its risk mainly comes from the scars of the uterus after the cesarean section. First of all, if the scar is not well healed, as the baby grows in the middle and late stages of pregnancy, it may "break" the uterus and endanger life. Secondly, the probability of cesarean section increases, and intraoperative bleeding is particularly threatening to pregnant mothers; and multiple operations will lead to increased complications, such as the risk of anesthesia, postoperative abdominal adhesions, and poor wound healing. Third, cesarean section is a high-risk factor for placental villi implantation. Simply put, the placenta grows into the muscle layer of the uterus. This condition can lead to massive bleeding, shock, uterine perforation, secondary infection, and even death. Finally, the risk of ectopic pregnancy, placenta previa, dangerous placenta previa, uterine rupture during pregnancy and childbirth, and other serious life-threatening complications is also significantly increased, and the uterus needs to be removed when life-threatening.

Older pregnant mothers may experience dystocia due to certain high-risk pregnancy diseases, which affects the time to labor and causes delayed labor. If the time for delivery is delayed, the physical strength of the pregnant mother will gradually decrease. In the end, the baby may experience distress, poor heart rate and other dangerous situations in the womb. Therefore, as a last resort, doctors will switch from natural birth to cesarean section.

In short, high-quality prenatal care requires early screening, early diagnosis, early intervention and early treatment, including the control of the factors that affect the morbidity of the elderly pregnant mothers, the correction of the factors that promote the morbidity of the elderly pregnant mothers, and more important pathogenic factors. Differential diagnosis and treatment of the disease.
