Why is IVF aging?
IVF technology is an advanced assisted reproductive technology. Through in vitro fertilization and embryo transfer, many couples who cannot conceive naturally can have their own children. However, recent studies have found that IVF may be aging both physically and psychologically. In order to better understand the causes of IVF aging, we can analyze it from the following aspects:
1. Risk of ectopic pregnancy
IVF transfers the fertilized eggs directly into the uterus, rather than through the natural cervical passage. This may increase the risk of ectopic pregnancy. Ectopic pregnancy refers to the implantation of fertilized eggs outside the uterus, most commonly in the fallopian tube. Ectopic pregnancy has serious complications, such as organ rupture and massive bleeding, which pose a threat to the health of mothers and fetuses.
The study found that the incidence of ectopic pregnancy was higher in IVF pregnancies than in natural pregnancies. This may be due to the changes in hormone levels and endometrial status brought about by the IVF technology itself. Ectopic pregnancy will not only damage the mother's reproductive system, but also may affect the embryonic development and normal growth of IVF, thus leading to aging.
2. Influence of genetic factors
IVF is obtained through in vitro fertilization. There may be a risk of gene mutation or chromosome abnormality during the process of embryo formation. These mutations and abnormalities may cause IVF babies to be born with certain genetic defects, thus increasing the risk of aging.
Studies have shown that compared with naturally conceived infants, IVF may have a higher rate of chromosomal abnormalities and genetic mutations. These genetic abnormalities may cause children to face more health problems in the process of growth and development, accelerating the process of aging.
3. Influence of social psychological factors
IVF is a fertility assistant technology with high physical and mental pressure. After a long and uncertain wait, the joy of successfully obtaining IVF is often accompanied by anxiety and tension. These negative emotions may have a negative impact on the physical health of IVF.
The study found that the psychological state of pregnant women can affect the development of the fetus through the changes in hormone levels. Anxiety, depression and long-term stress may lead to an increase in the level of cortisol in pregnant women, which may adversely affect the growth and development of IVF. These psychological factors may, to some extent, cause the aging phenomenon of IVF.
4. Physiological status of elderly puerpera
With the progress of society and the enhancement of women's independent consciousness, more and more women choose to postpone childbearing. However, age has an important impact on fertility and embryo quality. IVF technology can not change women's physiological status, therefore, elderly mothers often face more physiological restrictions.
The study found that the quality and quantity of eggs of the elderly mothers will gradually decline, leading to the reduction of the success rate of IVF and the decline of embryo quality. These factors may increase the risk of IVF aging.
summary
Although IVF technology has brought hope to many couples, compared with natural pregnancy, IVF may face more health risks, including aging. These risks can be attributed to the risk of ectopic pregnancy, the influence of genetic factors, social and psychological factors, and the physiological status of elderly mothers. In order to improve the success rate of IVF and reduce the occurrence of aging, it is necessary to strengthen the research on IVF technology, improve relevant medical services, and provide comprehensive physical and psychological support for couples.
