The problem that the second generation of IVF is easy to be deformed
With the development of medical technology, the second-generation IVF has become the gospel of infertile couples. However, compared with other birth methods, the second-generation IVF has certain risks and problems in some aspects. One of them is prone to malformation. This article will elaborate on the malformation problems of the second generation IVF from four aspects: genetic factors, mother's age, environmental factors and technical mistakes.
Genetic factor
The second generation of IVF is prone to some genetic abnormalities. This is because IVF transfers the fertilized eggs from one person to another through artificial assisted reproduction technology, which may lead to errors in the transmission of genetic information. For example, if the fertilized egg carries a gene mutation, the second-generation IVF may inherit this mutation, thus causing some malformation disease.
In addition, if both parents carry the gene of genetic disease, then combining the fertilized eggs of these two people and then transplanting them into the mother will increase the risk of the second-generation IVF suffering from genetic disease. Therefore, before the second generation of IVF, doctors should conduct a comprehensive examination and assessment of the genetic background of both spouses to avoid the transmission of genetic diseases.
Mother's age
The age of the mother is also an important factor in the malformation of the second-generation IVF. During the aging process of female reproductive system, the quality of eggs may decline, thus increasing the risk of embryo malformation. Especially for women over 35 years old, their egg quality will be more unstable, and the risk of malformation will increase accordingly.
In addition, older mothers are also associated with chromosomal abnormalities. Age may cause chromosomal abnormalities, such as Down syndrome. These chromosomal abnormalities often lead to congenital malformations in the second generation of IVF.
environmental factor
Environmental factors are also one of the important reasons for the second generation IVF malformation. The radiation, harmful chemicals or drugs that pregnant women are exposed to during pregnancy may have adverse effects on the normal development of the embryo. For example, maternal exposure to tobacco smoke or harmful chemicals may cause the second-generation IVF to suffer from respiratory or neurological abnormalities.
In addition, the diet, living habits and living environment of pregnant women during pregnancy will also affect the development of embryos. Poor eating habits, lack of exercise or overwork may increase the risk of embryo malformation.
Technical mistakes
There are certain risks in the operation of IVF technology. For example, in the process of taking the fertilized egg, if the operation is improper, the fertilized egg may be damaged or infected, which will affect the normal development of the embryo and increase the possibility of malformation.
In addition, the process of IVF transplantation into the uterus also requires a high degree of technical operation. Some technical errors, such as inaccurate transfer position and unreasonable operation time, may affect the implantation and development of embryos and increase the risk of malformation.
summary
In conclusion, the second generation IVF is prone to malformation, which is related to genetic factors, mother's age, environmental factors, technical errors and other factors. Therefore, before the second generation of IVF, doctors and couples should fully understand and assess the risks, and take appropriate measures to reduce the risk of malformation.
