Possible aspects of the third generation IVF sequelae
As a kind of assisted reproductive technology, IVF technology has brought hope and joy to many infertile couples. However, with the further development of technology, the third generation of IVF has also attracted people's attention to its possible sequelae. Here, we will elaborate on the possible sequelae of the third generation IVF from four aspects: genetic risk, multiple pregnancy, preterm delivery and psychological impact.
Genetic risk
In IVF, embryos can be screened for certain genetic diseases. However, this does not mean that there is no genetic risk at all. Because embryos with abnormal genes may be misjudged as normal, and new gene mutations may also occur with embryo transfer and development. Therefore, IVF is still at risk for genetic diseases.
In addition, due to the technical characteristics of IVF, the risk of genetic diseases between siblings may increase. For example, if the parents have some genetic disease, the children born through IVF technology may also carry the risk of this disease.
Therefore, genetic counseling and genetic screening are very important for parents who have given birth through IVF technology in order to reduce the risk of genetic diseases.
Multiple pregnancy
In IVF technology, in order to increase the success rate, multiple embryos are often implanted in the uterus. However, multiple pregnancy also brings a series of problems and risks.
First, multiple pregnancies increase the risk of premature delivery. Compared with single pregnancy, multiple pregnancy is more likely to lead to premature delivery, which increases the possibility of neonatal complications, such as respiratory distress syndrome, low birth weight, etc.
Secondly, multiple pregnancy also increases the risk of complications during pregnancy, such as hypertension and diabetes. At the same time, multiple pregnancy will also cause a greater burden on the body of pregnant women, increasing the discomfort and risk of pregnancy.
Therefore, in order to avoid the risk of multiple pregnancy, doctors will generally select the appropriate number of embryos for transplantation according to the situation, so as to minimize the probability of multiple pregnancy.
premature delivery
Preterm birth is another important problem that IVF may face. Because of the increased risk of multiple pregnancies, IVF babies are more prone to premature delivery.
The risks of premature delivery include immature respiratory system, incomplete digestive system, weak immune system, etc. Preterm infants usually need to be cared for in the intensive care unit, and there may be some delay in growth and development.
In order to reduce the risk of premature delivery, doctors usually take measures to extend the pregnancy period, such as early course management, rest and diet adjustment.
Psychological influence
The psychological impact of IVF cannot be ignored. After trying to conceive naturally without success, couples often have great expectations and anxiety. The success of IVF has an important impact on their psychological state.
On the one hand, the failure of IVF will give couples a heavy blow and sense of loss, which may lead to depression, anxiety and other psychological problems. On the other hand, if the pregnancy is successful, couples may be too nervous and worried, which will affect their mentality and physical and mental health during pregnancy.
Therefore, it is very important to provide mental health support during IVF. You can help couples deal with their emotions through professional psychological counseling or participating in related psychological counseling activities.
Summary
The possible sequelae of the third generation IVF mainly include genetic risk, multiple pregnancy, premature delivery and psychological impact. Genetic risk is related to the accuracy of embryo gene screening, gene mutation and genetic risk between siblings. Multiple pregnancy will increase the risk of premature delivery and complications of pregnant women, and doctors need to reasonably control the number of embryo transfers. Premature birth may lead to a variety of complications and delayed growth and development of newborns. The psychological impact of IVF has an important impact on the psychological status of couples, which needs psychological health support.
Therefore, for couples preparing for IVF, it is very important to understand the possible sequelae, and do a good job in genetic counseling, embryo number control, prevention of preterm birth, and mental health support.
