Will IVF technology increase the risk of infant disease?



introduction

IVF technology is a technology of in vitro fertilization, which is widely used to solve the problem of infertility. However, some people have raised concerns that IVF technology may increase the risk of infants suffering from diseases. This article will elaborate and discuss this problem from four aspects: genetic mutation, abnormal early embryonic development, multiple pregnancy and mental health.

Genetic mutation

In IVF technology, the genome of the embryo may be damaged, leading to an increased risk of certain diseases. A study conducted by scientists from Harvard Medical School and Massachusetts Institute of Technology found that there were more structural variations and single nucleotide variations in the genome of IVF embryos than those of naturally conceived embryos. These mutations may increase the risk of genetic diseases in infants. In addition, the genome of embryos in IVF technology is also more vulnerable to the impact of the external environment, such as the quality of the culture medium and the instability of the culture conditions, which may also lead to an increased risk of disease for infants. In addition, in IVF technology, it is often necessary to carry out gene testing on embryos to screen for embryo transfer without genetic diseases. However, gene detection is not 100% accurate, and there may be errors, which may lead to some embryos carrying genetic diseases being misjudged as risk-free. This increases the risk of infants suffering from genetic diseases.

Abnormal early embryonic development

In IVF technology, there are differences between the development environment of embryos in culture dishes and the intrauterine environment of natural pregnancy. This difference may have a negative impact on the development of embryos and increase the risk of some diseases. For example, a study found that test tube babies are more likely to suffer from cardiovascular diseases and metabolic diseases than naturally conceived babies. This may be because IVF embryos lack subtle signals in the womb environment in the culture dish, which leads to abnormal development of fetal organs. In addition, in IVF technology, excessive embryo transfer is often required to increase the probability of successful pregnancy. However, multiple pregnancies increase the risk of premature delivery and low birth weight infants, who are more likely to suffer from some health problems, such as pulmonary insufficiency and neurodevelopmental disorders. Therefore, abnormal early embryonic development will also increase the risk of infant disease.

Multiple pregnancy

In IVF technology, multiple embryo transfer is often used to increase the success rate of pregnancy. However, multiple pregnancies increase the risk of illness for infants. A study found that the death rate and birth defect rate of multiple pregnancy infants were significantly higher than those of single pregnancy infants. This may be due to the influence of multiple pregnancy on the mother and abnormal embryonic development. Therefore, multiple pregnancies increase the risk of illness for infants.

mental health

IVF technology may also have some impact on family mental health. A study found that the parents of test tube babies have higher levels of stress and are more likely to suffer from psychological diseases such as anxiety and depression. This psychological pressure may have a negative impact on children's health. The study also found that IVF may also face psychological problems during its growth, such as low self-esteem and identity problems. These psychological problems may lead to an increased risk of illness for infants.

summary

Although IVF technology is an effective means to solve the problem of infertility, it may increase the risk of disease for infants. Genetic mutation, abnormal early embryonic development, multiple pregnancy and mental health are the main reasons for this risk. Therefore, careful consideration should be given to IVF technology, and risk notification and psychological support for patients should be strengthened.
