Development trend of IVF technology
IVF technology is a method to help couples who cannot conceive in a natural way to achieve fertility through in vitro fertilization, embryo transfer and other technical means. With the continuous development of technology, IVF technology is also constantly innovating and improving, showing the following development trends:
1. Improve the accuracy and success rate of technical operation
With the continuous progress of science and technology, the manual operation in IVF technology has gradually achieved a high degree of accuracy. First of all, the development of in vitro fertilization technology makes the combination of sperm and egg more accurate, greatly improving the success rate of pregnancy. Secondly, the improvement of embryo culture technology enables scientists to better simulate the natural embryo development environment and improve the survival rate and quality of embryos. Finally, the accuracy of embryo transfer technology continues to improve, which greatly increases the success rate of transfer. These technological breakthroughs have made the success rate of IVF technology increase year by year.
For example, the Assisted Reproduction Center of Peking Union Medical College Hospital of the Chinese Academy of Medical Sciences has successfully helped a large number of couples achieve their reproductive aspirations by using accurate operation and optimized embryo culture technology.
2. Risk reduction of multiple pregnancy
In the past, in order to improve the success rate of IVF, doctors often transplanted multiple embryos together, leading to a significantly increased risk of multiple pregnancies. However, multiple pregnancy often causes a series of complications, which seriously affect the health of embryos and mothers. With the development of technology, IVF technology can reduce the risk of multiple pregnancy through screening and optimization.
For example, Prada Reproductive Center in the United States has adopted a technology called PGS (Preimplantation Genetic Screening), which can detect chromosomal abnormalities of embryos before transplantation and screen healthy embryos for transplantation, thus reducing the risk of multiple pregnancy.
3. Single nucleotide polymorphism (SNP) analysis
Single nucleotide polymorphism analysis is a gene detection technology, which can evaluate the genetic health of embryos by analyzing the SNPs of gene fragments. This technology can screen out the risks of some genetic diseases before embryo implantation, and help couples choose healthy embryos for transplantation.
For example, the London Baby Clinic in the UK launched SNP Array technology, which can help couples prevent the occurrence of certain genetic diseases.
4. Wide application of frozen embryo technology
Frozen embryo technology is a commonly used method of embryo preservation in IVF technology. Unused healthy embryos are usually frozen for future use. In recent years, frozen embryo technology has been widely used and made significant progress.
For example, the Melbourne Test Tube Baby Center in Australia has been able to freeze embryos for more than 20 years, take them out and successfully implant them. This provides more options for couples who need multiple transplants to improve their success rate.
Summary
With the continuous progress of science and technology, IVF technology has made major breakthroughs in accuracy and success rate, multiple pregnancy risk, gene detection and embryo preservation. The current development trend is to further improve the accuracy of technical operation, reduce the risk of multiple pregnancy, apply gene detection technology and widely promote frozen embryo technology. These advances will further improve the success rate and safety of IVF technology and help more couples achieve their reproductive aspirations.
