Concept of three generations of IVF
The third generation IVF is an assisted reproductive technology, which helps couples solve their fertility problems by using nuclear transfer of fertilized eggs. This technology can help couples who are unable to conceive through conventional methods realize their desire to have children. The third-generation IVF technology provides greater flexibility and can better eliminate some genetic defects that lead to infertility.
Three generation IVF technology is developed on the basis of conventional IVF technology. The conventional IVF technology is to transfer the fertilized egg into the abdominal cavity or uterus, while the third generation IVF technology is to transfer the nucleus of the fertilized egg into the recipient egg cell, and then transfer the synthetic fertilized egg back to the mother. This technology was first successfully born in a private clinic in London, England, and has now been gradually promoted worldwide.
Gender Selection of Three Generation IVF
In conventional IVF technology, sex selection is mainly carried out by screening chromosomes. However, the third generation IVF technology can further select the sex of embryos.
Thanks to the progress of technology, the third generation IVF technology can select embryos with specific genetic defects and select healthy sex embryos for transplantation. For example, chromosome related diseases, such as hemophilia and muscular dystrophy, can be prevented from being passed on to the next generation by screening embryos for sex selection.
However, in some countries, there are legal restrictions on gender selection for non-medical needs. In some places, this technology is only allowed to be used when it is medically necessary.
Risks of the third generation IVF technology
Although the third-generation IVF technology can help couples achieve their reproductive aspirations, there are also some risks.
First of all, the operation itself has certain risks. The transplantation process may lead to bleeding, infection and other complications.
Secondly, three generation IVF technology may lead to the transmission of genetic diseases. Although technology can help to screen out some known genetic defects, it may still miss some potential genetic problems. In addition, the process of nuclear transplantation itself may also trigger new gene mutations.
In addition, the quality of recipient oocytes is also one of the key factors in the success rate. Poor quality of recipient oocytes may lead to poor embryos and affect the outcome of pregnancy.
conclusion
Three generation IVF technology provides more choices in assisted reproductive technology, including embryo sex selection and genetic defect screening. Although the use of the third-generation IVF technology in some countries is restricted by law, it is still a promising choice in the case of meeting medical needs. However, we also need to clarify the risks of the three generation IVF technology, including the risk of surgery, the risk of transmission of genetic diseases and the impact of embryo quality. When choosing this technology, couples need to fully communicate with doctors, weigh the advantages and disadvantages, and make wise decisions.
