New breakthrough in IVF II technology
The second generation of IVF technology has become an effective way for many infertile couples to achieve their reproductive aspirations. With the continuous development of science and technology, IVF II technology is also making new breakthroughs. This article will elaborate on the new breakthrough of IVF second-generation technology from four aspects: gene screening, embryo implantation, embryo culture and embryo freezing.
Gene screening
Gene screening is an important part of IVF second generation technology. The transmission of some hereditary diseases can be avoided by genetic screening of embryos. With the development of gene sequencing technology, the accuracy and feasibility of gene screening are constantly improved. For example, the California Reproductive Science Center in the United States has adopted large-scale parallel sequencing technology, which can quickly and accurately screen more than 100 genetic diseases. In addition, the team has also developed non-invasive gene screening technology, which can avoid damage to embryos by extracting fetal free DNA from maternal blood for analysis.
The breakthrough in gene screening not only makes the IVF technology more safe and reliable, but also provides couples with the opportunity to choose healthy embryos, increasing the possibility of having children.
Embryo implantation
Embryo implantation is one of the key steps of IVF second generation technology. With the progress of technology, the success rate of embryo implantation is gradually improving. For example, the Robert Wyndham Center for Reproductive and Embryology in the UK carried out a study, and the success rate of using new implantation technology exceeded 75%. They adopted an embryo monitoring system called Time Lapse, which can observe the development of embryos in real time, select the best time for implantation, and greatly improve the success rate of implantation.
In addition, some innovative embryo implantation technologies have emerged, such as photon pestle technology and monoclonal antibody technology. The photon pestle technology can accurately locate the embryo by using a photon probe, which reduces the damage during implantation and improves the success rate of implantation. Monoclonal antibody technology can avoid the risk of implantation of low-quality embryos by accurately identifying and selecting the most promising embryos.
Embryo culture
Embryo culture is another key link in the second generation technology of IVF. The longer the embryo is cultured in vitro, the greater the possibility of survival and development. In order to improve the success rate of embryo culture, scientists have carried out a series of research and innovation.
For example, the medical center of the Hebrew University in Jerusalem, Israel, carried out a study and successfully developed the "dynamic embryo culture" system. The system can simulate the physiological environment in the mother, provide more stable and suitable culture conditions for embryos, and improve the chances of embryo survival and development. In addition, the application of some new media, such as deadhesive media and mitotic arrest factor media, has also achieved good results.
embryo freeze
Embryo freezing is an important step in the second generation technology of IVF, so that healthy embryos can be reserved for future use. In recent years, embryo freezing technology has also made new breakthroughs.
For example, Peking Union Medical College Hospital in China carried out a research and successfully developed a new type of rapid freezing technology. This technology can freeze embryos to extremely low temperature in a short time, reducing the damage of embryos and even cells. At the same time, the new saturated gas phase freezing method can also reduce the direct contact of liquid nitrogen to embryos, and maintain the integrity and vitality of embryos.
In short, IVF II technology has made new breakthroughs in gene screening, embryo implantation, embryo culture and embryo freezing. These breakthroughs not only improve the feasibility and success rate of technology, but also provide more choices and hopes for infertile couples and new possibilities for them to realize their reproductive aspirations.
