Development of IVF technology
In vitro fertilization embryo transfer (IVF-ET) has reached a very high level. Through the continuous innovation and improvement of assisted reproductive technology, IVF technology has made great achievements in solving the problem of infertility. The following will elaborate on the development of IVF technology from different aspects.
Patient screening and optimization
With the progress of gene detection technology, IVF technology can screen and optimize patients more accurately. Through gene sequencing technology, some genetic disease risks can be detected, so as to select embryos without pathological genes for transplantation. In addition, IVF technology can also help couples with genetic disease genes to reduce the risk of having children with genetic diseases by selecting healthy embryos for transplantation. For example, a hospital in New York successfully selected a healthy test tube baby for a couple with genetic disease genes.
In addition, IVF technology can also treat infertility caused by irreversible factors such as chromosome abnormalities. Through in vitro fertilization embryo transfer technology, these couples can choose healthy embryos and improve the success rate of pregnancy.
Improvement of migration program
With the development of technology, the procedure of IVF transplantation has also been improved. First, through minimally invasive surgery technology, the process of egg retrieval and embryo transfer becomes safer and faster, and reduces the pain of patients. Secondly, with the help of microinjection technology, sperm can be more accurately injected into the egg to improve the fertilization rate. Then, combined with the improvement of gamete screening technology and embryo culture technology, more healthy and high-quality embryos can be screened to reduce the rate of transplant failure. These improvements make the success rate of IVF technology continuously improve.
Preembryonic genetic diagnosis technology
Preembryonic genetic diagnosis technology is one of the important development directions of IVF technology. Through gene testing of embryos, embryos without certain genetic disease risks can be screened before transplantation. At present, the pre embryonic genetic diagnosis technology has been developed, including extensive detection of genome, single gene disease analysis, etc. The application of these technologies can not only reduce the risk of children suffering from genetic diseases, but also improve the success rate of IVF technology.
Alternative selection
Although IVF technology has developed to a very high level, there are still some problems. First, IVF technology has a low success rate for older women. Secondly, complications and risks related to IVF technology cannot be ignored, such as multiple pregnancy and reproductive tract infection. Therefore, for some special circumstances, such as older age or other unsuitable factors, other options, such as adoption, can be considered.
To sum up, with the progress of science and technology, IVF technology has made important progress in patient screening and optimization, improvement of transfer procedures, and preembryonic genetic diagnosis. However, its limitations and risks still need to be taken into account, and other options should be provided for the appropriate patients. Therefore, before the application of IVF technology, it is still necessary to comprehensively consider a variety of factors and choose an appropriate scheme.
