What are the new technological advances of the third generation IVF?
Since the birth of the first test tube baby, the technology of test tube baby has undergone many years of development and progress. The third generation of IVF refers to the babies who develop in vitro fertilized eggs through artificial assisted reproduction technology, and then implant the embryos with good growth potential into the mother's body. In the third generation of IVF technology, there have been many new technological advances, making IVF technology more accurate and effective.
Embryo screening technology
Embryo screening technology is an important progress in the third generation of IVF. The traditional IVF technology can only implant the fertilized egg into the mother, and cannot predict the development of the embryo after implantation. The modern embryo screening technology can select the embryo with the best growth potential for implantation through the gene detection of the fertilized egg and the evaluation of the embryo development. This technology not only improves the success rate of IVF, but also reduces the risk of multiple pregnancy, providing patients with better reproductive options.
There are two main methods for embryo screening: gene screening and morphological evaluation. Gene screening technology can detect genetic diseases and chromosomal abnormalities of embryos, such as Down syndrome, blastocyst disease, etc. Morphological assessment assesses the development potential and quality of the embryo by observing the external morphology and cell development of the embryo.
At present, many professional reproductive centers and hospitals have begun to apply embryo screening technology to provide comprehensive and accurate embryo selection services for IVF patients.
Single nucleotide polyploid detection technology
Single nucleotide polyploid detection technology is an innovative progress in the third generation of IVF technology. In the past, embryo screening can only determine whether an embryo has abnormalities by observing the number of chromosomes in the embryo. However, many chromosomal abnormalities cannot be observed by numerical changes. Single nucleotide polyploid detection technology can accurately detect chromosomal abnormalities of embryos, including chromosome deletion, duplication and inversion, by sequencing the cell genome.
The application of single nucleotide polyploid detection technology makes IVF embryo screening more accurate and reliable, and greatly improves the success rate of IVF. This technology is being applied in some advanced reproductive centers and has achieved remarkable results.
Frozen egg technology
The traditional IVF technology requires fresh eggs to be taken out in each cycle for insemination and culture. The emergence of frozen egg technology enables eggs to be frozen at the best time for future use.
The advantage of frozen egg technology is that it can reduce the cost and risk of IVF treatment. The patient can freeze the egg at the right time, and then implant the embryo at the right time. This can avoid the pain and risk of taking eggs every cycle, and also provide greater flexibility and selectivity.
Embryo culture technology
Embryo culture technology is also one of the important advances in the third generation of IVF technology. In traditional IVF technology, fertilized eggs can only be cultured in petri dishes. However, the embryo develops in the natural environment, which is quite different from the maternal environment.
Modern embryo culture technology can simulate the environment inside the mother, providing a more realistic culture environment for embryos. For example, the in vitro incubator can control parameters such as temperature, humidity and oxygen concentration to make the development of embryos more stable and healthy.
In addition, the application of some new embryo culture media can provide a more suitable nutritional environment for embryo development and further improve the success rate of IVF.
Summary
The third generation IVF technology has made significant progress in embryo screening, single nucleotide polyploid detection, frozen eggs and embryo culture. These new technologies make IVF treatment more accurate, safe and effective. With the continuous development of medicine and technology, it is believed that the third generation IVF technology will continue to make new breakthroughs and progress, bringing good news to more infertile patients.
