What is the third generation of IVF
IVF is a kind of assisted reproductive technology, which aims to help couples who experience infertility to achieve their reproductive aspirations. The third generation of IVF refers to the IVF technology further developed on the basis of the previous two generations. Compared with the previous two generations, the third generation IVF technology is more advanced and accurate, which can provide more genetic information and further increase the fertility success rate.
In order to realize the third generation of IVF, in vitro fertilization (IVF) is the first step. This includes combining an egg taken from a female ovary with a male sperm to make it become an embryo in the laboratory. Then, embryos with good genetic status are screened out for transplantation through embryo genetic testing and other technologies.
The third generation of IVF has made breakthroughs in embryonic genetic testing, which are specifically reflected in the following aspects.
Gene screening
The third generation of IVF can conduct gene screening to detect the risk of genetic diseases carried by embryos. Through embryonic genetic testing, we can find whether there are chromosomal abnormalities in embryos, such as Down's syndrome, Edwards syndrome, etc., so as to help couples choose healthy embryo transfer and avoid genetic diseases.
The development of gene screening technology makes the third generation of IVF more accurate and safe. For example, using the new generation sequencing technology, thousands of genes can be detected at the same time to accurately determine whether the embryo carries a specific genetic disease gene. This greatly improves the success rate and reduces the risk of genetic diseases.
Genetic diagnosis
The third generation of IVF can also carry out genetic diagnosis to solve couples' specific fertility problems. For example, for some couples who are unable to conceive naturally, genetic diagnosis technology can help them find appropriate fertility methods, such as choosing tubal pregnancy or further increasing fertility opportunities.
The application of genetic diagnosis technology makes the third generation of IVF more comprehensive and personalized in solving the problem of infertility. Hospitals such as Peking Union Medical College Hospital have begun to use this technology to provide professional genetic counseling and diagnostic services for couples.
Embryonic gene editing
The third generation of IVF also involves the application of embryonic gene editing technology. With CRISPR-Cas9 and other gene editing tools, embryos can be precisely genetically modified. This technology can be used to remove embryos with genetic disease gene mutations, thereby reducing the risk of genetic diseases and achieving the birth of healthy offspring.
Embryonic gene editing technology is still in the experimental stage. Although it has potential application prospects, there are still some ethical and moral issues to be considered. Therefore, it has not been widely used in clinical practice.
The third generation price of IVF
The third generation of IVF is a high-tech medical service, so the price is relatively high. The specific price varies according to different regions and hospitals.
Taking Peking Union Medical College Hospital as an example, the price of the third generation of IVF is about 300000 to 500000 yuan. This price includes all medical expenses, including in vitro fertilization, embryonic genetic testing, transplantation and other costs.
It should be noted that the high price of the third generation of IVF is mainly due to the complexity of technology and the investment of medical resources, as well as the high laboratory costs of embryonic genetic testing and gene editing.
