Can IVF be inherited after success
As an advanced assisted reproductive technology, IVF has been widely used and achieved great success all over the world. However, many people have doubts about whether IVF will inherit some undesirable genes or diseases after success. This article will elaborate on this issue from the perspective of genetics, as well as the evidence of practical medical practice and other aspects.
Genetic perspective
First, from the perspective of genetics, there is no difference between the genetic characteristics of IVF and those of naturally conceived infants. The fertilization process of IVF is to combine eggs and sperm in vitro, then cultivate them into embryos, and then implant them into the mother. This means that the genes carried by IVF are all from parents, and no additional genetic material is involved. Therefore, the genetic composition of IVF is basically the same as that of its parents, and there is no essential difference between IVF and naturally conceived infants.
Secondly, IVF technology does not increase or reduce the risk of a person suffering from a genetic disease. The occurrence of genetic diseases mainly depends on the probability that parents carry related gene mutations. Whether it is a natural pregnancy or a test tube baby, the risk of children suffering from genetic diseases depends on their parents' genetic conditions. Therefore, the success of IVF will not affect the risk of genetic diseases.
In addition, IVF technology also provides parents with the opportunity to screen for gene mutations. Through PGD (Preimplantation Genetic Diagnosis) technology, doctors can conduct gene testing on IVF embryos, screen out embryos carrying gene mutations of certain genetic diseases, and select healthy embryos for implantation. This screening technology can effectively reduce the risk of genetic diseases and improve the health of infants.
Evidence of medical practice
A large number of medical practices have proved that there is no significant difference between the genetic characteristics of IVF and those of naturally conceived infants. Take Luo Zhili, a senior Chinese reproductive expert, as an example. He has successfully performed many IVF operations in the clinical practice of Beijing Boda Reproductive Hospital, and has achieved excellent results. He said that many of his patients were unable to conceive or prone to miscarriage due to genetic reasons. Through IVF technology, these couples successfully welcomed healthy babies.
In addition, there are many famous successful cases of IVF in the world. For example, the Lloyd family in Britain, the first test tube baby family in the world, has been developing for 35 years. Their children have no significant differences in growth, development and intelligence from those naturally conceived, which proves that IVF is not different from those naturally conceived at the genetic level.
More similar medical practice evidence shows that with the help of modern medicine, the genetic characteristics of IVF are not significantly different from those of naturally conceived infants. The success of IVF mainly depends on the genetic composition of parents and the technical level of doctors, without introducing additional genetic risks.
Significance of IVF
Test tube baby technology is not only important to solve the problem of infertility, but also plays an active role in the prevention and treatment of genetic diseases. The application of PGD technology can screen some genetic diseases before embryo implantation and select healthy embryos for implantation, thus effectively reducing the risk of genetic diseases. The success of IVF will not increase or reduce the probability of genetic diseases, but it can effectively reduce the transmission of genetic diseases to the next generation through technical means.
Summary
In conclusion, IVF will not inherit additional genes or diseases after success. From the perspective of genetics, the genetic composition of IVF is basically the same as that of its parents, without any difference. From the evidence of medical practice, there is no significant difference between IVF and naturally conceived children in terms of growth, development and intelligence. IVF technology can reduce the risk of genetic diseases through PGD and other screening methods, which is of positive significance for the prevention and treatment of genetic diseases. Therefore, IVF is a safe and reliable fertility assistance technology, which can help infertile couples achieve their fertility aspirations and reduce the impact of genetic diseases on the next generation.
