Progress of the third generation of IVF
The development of IVF technology has provided new hope for those couples who cannot achieve their reproductive aspirations through natural pregnancy. With the continuous progress of science and technology, the emergence of the third generation of IVF technology makes infertility patients more likely to achieve healthy and successful pregnancy. This article will elaborate on the progress of the third generation IVF from four aspects: embryo screening, embryo implantation, PGS technology and pregnancy success rate.
Improvement of embryo screening technology
Embryo screening technology is a key link in the process of IVF, which can predict the potential risk of embryo disease before embryo implantation. With the continuous progress of genetics and biotechnology, the screening process of new life embryos has become more accurate and reliable. At present, some well-known hospitals have used the latest technology to carry out gene editing, which can treat some genetic diseases by changing embryonic DNA, and greatly improve the effect of embryo screening.
However, the improvement of embryo screening technology has also brought ethical and moral concerns. When using gene editing and other technologies, medical personnel need to operate carefully to ensure compliance with relevant ethical standards, so as to avoid unpredictable effects on human genes.
Improvement of embryo implantation technology
Embryo implantation is one of the key steps for the successful implementation of IVF. In recent years, the improvement of embryo implantation technology has significantly improved the success rate. Hospitals such as Peking Union Medical College Hospital and Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine have introduced the whole process electronic embryo monitoring system, which can observe the development and quality of embryos in real time, thus improving the success rate of embryo implantation.
In addition, some research institutions are also exploring more advanced embryo implantation technologies, such as targeted gene editing in IVF and gene repair before embryo implantation. The introduction of these technologies will further improve the success rate of IVF and enable more couples to realize their reproductive dreams.
Application of PGS technology
PGS (Preimplantation Genetic Screening) technology is an important progress in the third generation of IVF. The technology detects the number and structure of chromosomes of preimplantation embryos, screens out embryos with abnormal chromosomes, and selects healthy embryos for implantation. The application of PGS technology has greatly improved the success rate of IVF and reduced the risk of abortion and fetal malformation caused by chromosomal abnormalities during pregnancy.
Some well-known hospitals, such as Guangzhou Women and Children's Medical Center, Fudan University Affiliated Obstetrics and Gynecology Hospital, have successfully applied PGS technology and achieved remarkable results in clinical practice. These successful cases prove the importance of PGS technology in improving the success rate of IVF pregnancy.
Improvement of pregnancy success rate
With the continuous development of the third generation IVF technology, the pregnancy success rate has also been greatly improved. Famous hospitals such as the Affiliated Obstetrics and Gynecology Hospital of Zhejiang University School of Medicine and West China Hospital of Sichuan University have introduced new technologies and continuously optimized the operation process of IVF, which has significantly improved the pregnancy rate and live birth rate.
However, although the third-generation IVF technology has made remarkable progress, it still needs to strictly follow medical ethics and laws and regulations to ensure the rational application of technology. At the same time, scientists and doctors should also continue to devote themselves to research, further improve technology, improve the success rate of IVF fertility, and let more couples who cannot conceive naturally realize their dreams of fertility.
Summary
The progress of the third generation of IVF has made remarkable achievements in embryo screening, embryo implantation, PGS technology and pregnancy success rate. The improvement of embryo screening technology and embryo implantation technology has greatly improved the success rate of IVF. The application of PGS technology reduces the risk caused by chromosome abnormalities. The increase in the success rate of pregnancy has made more infertile couples realize their desire to have children. However, the rational application of technology and strict compliance with ethical standards are still important topics for the development of the third generation IVF technology.
