What factors will increase the risk of elder childbearing?
With the development of society and the progress of medical technology, more and more women choose to postpone childbearing, thus increasing the risk of elderly childbearing. So, what factors will increase the risk of elderly childbearing? From many aspects:
Aging of reproductive system
With the increase of age, a series of aging changes will occur in the female reproductive system, such as the decline of ovarian function and egg quality. These factors will directly affect the pregnancy ability and embryo quality, and increase the risk of elderly childbearing.
First of all, with the growth of age, women's ovarian function will gradually decline, and the number of eggs will also decrease. This will lead to a decrease in the frequency of ovulation, thereby reducing the chance of pregnancy. At the same time, due to the decline in egg quality, it is easy to lead to abnormal embryonic development after fertilization or an increased risk of early abortion.
In addition, the aging of the female reproductive system can also lead to problems such as endometrial thinning, reduced blood supply, reduced conditions for implantation and embryonic development, and further increased the risk of elderly childbearing.
Increased risk of illness
The risk of illness of elderly pregnant women will also increase accordingly. The growth of age leads to the decline of functions of various systems of the body, weakened immunity, and correspondingly weakened resistance to various diseases. At the same time, the risk of suffering from some chronic or serious diseases will also increase with age.
For example, the probability of older pregnant women suffering from pregnancy complications such as gestational diabetes mellitus and maternal hypertension will increase significantly. These complications will not only increase the risk of pregnant women, but also affect the development of the fetus.
In addition, older pregnant women are more likely to be infected with various viruses and bacteria, such as influenza and pneumonia, due to their reduced physical resistance. If these diseases are infected during pregnancy, it will have adverse effects on the health of the fetus.
Increased risk of chromosomal abnormalities
With the increase of age, the probability of chromosomal abnormalities in female eggs will also increase accordingly. This is because the egg is formed during the development of the female embryo, and the development of the egg begins before the formation of the female embryo.
Specifically, a woman's egg has been formed when she is pregnant. With the increase of age, the probability of abnormal chromosomes in the egg gradually increases. These chromosomal abnormalities, including Down syndrome, will increase the risk of fetal disease.
Increased risk of pregnancy complications
Older pregnant women are also more likely to suffer from some pregnancy complications due to aging and other factors, increasing the risk of pregnancy.
For example, older pregnant women may face a higher risk of miscarriage. Due to the decline of egg quality, the probability of abnormal embryonic development will also increase, which leads to a significant increase in the probability of miscarriage of elderly pregnant women.
In addition, older pregnant women may also face higher risk of perinatal complications, such as premature delivery, placental insufficiency, etc. These complications not only affect the health of pregnant women, but also adversely affect the development and health of the fetus.
summary
In conclusion, aging of the reproductive system, increased risk of disease, increased risk of chromosomal abnormalities and increased risk of pregnancy complications are important factors leading to the increased risk of fertility in the elderly. Therefore, for women whose family planning is delayed, it is necessary to fully understand these risk factors and make relevant preparations and health care under the guidance of doctors to reduce the risk of elderly childbearing.
