The Latest Development of IVF Technology in the United States
In Vitro Fertilization (IVF) is an assisted reproductive technology, which helps couples who cannot conceive naturally realize their fertility aspirations by fertilizing eggs and sperm in vitro, and then implanting the fertilized eggs into the mother's uterus. In the United States, since the first successful application of IVF technology in 1978, it has developed into a mature medical technology and continues to make new progress. The following will introduce the latest progress of IVF technology in the United States from four aspects.
1. Progress in embryo screening technology
Embryo screening technology is an important part of IVF technology, which can help couples choose the most fertile embryos. The latest progress lies in the use of gene detection technology to detect whether embryos carry certain genetic diseases or chromosomal abnormalities. For example, some hospitals have introduced the second generation sequencing technology, which has the advantages of wide detection range, high accuracy and fast analysis speed. It can help couples screen healthy embryos and reduce the risk of birth defects.
In addition, embryo screening technology can also predict the sex of embryos. For some couples who prefer to have children, this technology can meet their needs to have boys and girls. However, the ethical issues and moral disputes related to embryo screening technology have gradually surfaced and need further discussion and regulation.
2. Improvement of frozen embryo technology
Frozen embryo technology is an important step in IVF technology. For those couples who need to try many times, frozen embryos can provide more pregnancy opportunities. The latest progress lies in the preservation of frozen embryos and the improvement of thawing technology. Using new freezing methods and equipment, the preservation effect of embryos has been significantly improved, and the damage of embryos during freezing and thawing has been reduced.
In addition, the preservation time of frozen embryos has also been extended. Some hospitals have successfully preserved embryos for more than 10 years, and successfully pregnant and delivered them. This provides more flexibility and choice space for those couples who need to postpone the birth plan or try for a longer time.
3. Improvement of sperm quality assessment technology
The quality of sperm plays an important role in the success of IVF technology. The latest progress lies in the improvement of sperm quality assessment technology. Some hospitals have introduced high-resolution microscopes and microsurgery systems, which can accurately evaluate and screen the morphology, vitality and concentration of sperm.
In addition, some researches are also devoted to developing new sperm treatment methods to improve fertilization rate and embryo development quality. For example, the application of centrifugation and activator can minimize the DNA damage of sperm and improve the success rate of embryo transfer of fertilized eggs.
4. Application of pulsed electromagnetic radiation technology
Some studies have shown that pulsed electromagnetic radiation can promote pregnancy and embryonic development. The latest progress lies in the application of pulsed electromagnetic radiation technology in IVF technology. Some hospitals have adopted this technology to improve the success rate of IVF and the quality of embryo development by adjusting the frequency and intensity of radiation.
In a word, IVF technology in the United States has made new progress in embryo screening, frozen embryos, sperm quality assessment and pulsed electromagnetic radiation. The continuous improvement and innovation of these technologies provide more hope and options for couples who cannot conceive naturally. However, with the emergence of new technologies, ethical issues and moral disputes cannot be ignored, and extensive discussion and supervision are needed to ensure the rational application of IVF technology.
