Although reproductive function seems to be a very normal thing, it gives many people the illusion that natural reproduction is a natural thing. But in reality, this is not the case at all. Once you get older, the difficulty of having a natural birth is very high. In addition, there have been rumors that giving birth at an advanced age can have an impact on the intelligence of children born, and even lead to deformities. So are these rumors true?

1、 How dangerous is giving birth to elderly pregnant women?

Due to various reasons such as work, many women miss the optimal age for childbirth and have to become elderly women. Elderly women generally refer to pregnant women over the age of 35 who become pregnant for the first time. They are at a disadvantage in age and are more prone to accidents during pregnancy, causing greater harm to elderly women. Therefore, we need to pay more attention to physical examinations before and during pregnancy, and keep an eye on the baby's development at all times. The hazards of elderly women include repeated abortion, hypertensive disorder during pregnancy, dystocia, cesarean section, diabetes during pregnancy, fetal development abnormalities, etc.

2、 Do older children have an impact on their IQ?

After the birth of a baby, many parents find it difficult to detect intellectual disability at the beginning, as most intellectual disabilities only manifest as cognitive impairments without obvious functional impairments. People aged 35 and above are referred to as "elderly women". When women reach middle age, their ischium, pubis, ilium, and cuboid bones are basically ossified, forming a fixed pelvic cavity, which is prone to fetal distress due to fetal retention in the uterus, which is extremely detrimental to the fetus. Generally, elderly women have no impact on their children's intelligence, but for them, the likelihood of danger is higher. After pregnancy, it is important to rest and not overwork. Regularly go to the hospital for relevant prenatal examinations and observe the development of the fetus. It is recommended that we develop good habits in daily life. It is best to go to bed and wake up early to ensure sufficient sleep, which is very beneficial for the development of the fetus. At the same time, it is also important to pay attention to diet, improve nutrition appropriately, and eat more foods with high protein or vitamins to supplement the body. Usually, the children of elderly women, like ordinary children, have no scientific basis to have intelligent babies. Generally speaking, if a baby is over 35 years old, the likelihood of chromosomal aberration increases. Meanwhile, if the mother is too old, more complications may occur. So it is not recommended to conceive at an advanced age, as it can easily lead to accidents.

3、 Is there a high probability of fetal malformation in elderly mothers?

Clinically, women over 35 years old are classified as elderly mothers and are high-risk factors for abnormal fetal chromosome data. The probability of fetal structural abnormalities in the general population is less than 5%, but as the mother's age increases, the probability of fetal abnormalities increases. Data shows that the incidence of fetal chromosomes in the general population is about 1:800, and the incidence of fetal chromosomes in pregnant women over 35 years old is 0.4%. If a pregnant woman is over 40 years old, the risk increases to 1.4%. Abnormal fetal morphology and structure are mainly congenital malformations, such as anencephaly, spina bifida, abnormal cleft lip and limbs, etc. As the mother's age increases, the probability of the fetus developing Down syndrome also increases. At the age of 35, the probability of a baby developing Down syndrome is 1 in 350; When the mother is over 40 years old, the probability of the fetus developing Down syndrome increases to 1 in 100. In addition to increasing the probability of congenital malformations during pregnancy, elderly women also have many other risks, such as miscarriage, premature birth, stillbirth, etc. Female fertility reaches its peak at the age of 20-24, significantly decreases after the age of 30, less than 5% after the age of 40, and less than 1% after the age of 45. The abortion rate for women is low before the age of 30, increases by 20% after the age of 35, and sharply increases after the age of 40, so the probability of women having a baby smoothly at the age of 46 is relatively low.

Overall, the probability of fetal malformation caused by elderly mothers is a bit high. If they are not careful or have not undergone a complete prenatal examination, the occurrence of fetal malformation is almost a high probability event. So the best solution to fetal malformations is to screen embryonic genes through third-generation in vitro fertilization technology. This method can completely eliminate the probability of fetal malformation, and is the best preventive method!
