New breakthrough in IVF technology
In recent years, with the progress of science and technology and the deepening of medical research, IVF technology is also constantly making new breakthroughs. The development of this technology provides a feasible reproductive choice for couples who cannot conceive naturally or suffer from specific reproductive disorders. The following is a detailed description of the new breakthroughs in IVF technology from four aspects: embryo selection, embryo transfer, frozen embryos and PGD technology.
Embryonic selection
Embryo selection is a key step in IVF technology. Traditional embryo selection usually depends on the appearance and chromosome structure of the embryo. However, this method can only provide limited information, and it is difficult to accurately judge the health status of embryos. In recent years, the development of new embryo selection technology has provided a higher possibility for the success rate of IVF. For example, single cell sequencing technology based on genomics can comprehensively analyze genetic variation in embryos, detect potential genetic disease risks, and help couples select the embryos with the most healthy potential for transplantation.
In addition, in terms of embryo selection, some hospitals have begun to use non-invasive embryo evaluation techniques, such as time period analysis and resistivity measurement. These technologies can comprehensively assess the quality and health of embryos and improve the success rate of IVF by monitoring the development speed, cell division, resistivity and other indicators of embryos.
embryo transfer
Embryo transfer is a very important step in IVF technology. Traditional embryo transfer methods usually use microscope to observe embryos, and select suitable embryos for transfer according to their appearance characteristics. However, this method relies on the experience and subjective judgment of observers to judge the quality and health of embryos, which is prone to miscalculation.
In recent years, some hospitals have begun to adopt new embryo transfer technologies, such as time period analysis and dynamic embryo management. Time period analysis judges the quality and health of embryos and improves the accuracy of embryo transfer by observing the development and internal changes of embryos in culture dishes. Embryo dynamic management combines time segment analysis and real-time image processing technology, which can monitor the development process of embryos in real time, and make embryo selection and transfer decisions according to the dynamic changes of embryos, further improving the success rate of IVF.
frozen embryo
Frozen embryo technology is an important part of IVF technology, which can improve the success rate of IVF. The traditional methods of freezing embryos usually use slow freezing technology or liquid nitrogen freezing technology, but these methods have a certain impact on the survival rate and survival rate of embryos. In recent years, the emergence of new frozen embryo technology has significantly improved the success rate of IVF.
At present, some hospitals have begun to use new frozen embryo technologies, such as ultrafast freezing technology and pre freezing embryo culture technology. These technologies can reduce embryo damage during embryo freezing and improve the survival rate and survival rate of embryos. In addition, the new frozen embryo technology can better protect the genetic information and morphological structure of embryos, provide better conditions for embryo transfer and implantation, and improve the success rate of IVF.
PGD technology
PGD (Preimplantation Genetic Diagnosis) technology is one of the important means in IVF technology. It can screen embryos for genetic diseases before embryo transfer and select healthy embryos for transfer, thus reducing the risk of genetic diseases in infants.
In recent years, PGD technology has made new breakthroughs in the scope and accuracy of diagnosis. Traditional PGD technology usually can only detect a few genetic diseases, such as Down syndrome and blastocyst fibrosis. Now, some hospitals have introduced PGD technology based on whole genome sequencing, which can detect hundreds of genetic diseases and ensure more accurate and comprehensive embryo health. In addition, the new PGD technology can also carry out early screening for some common genetic diseases, help couples prevent the risk of genetic diseases, and improve the success rate of IVF.
Summary
IVF technology has made new breakthroughs in embryo selection, embryo transfer, frozen embryos and PGD technology. In terms of embryo selection, genomics based single cell sequencing technology and non-invasive embryo evaluation technology can provide more accurate and comprehensive embryo health information. In terms of embryo transfer, time period analysis and embryo dynamic management technology can improve the accuracy of embryo selection and transfer. In terms of frozen embryos, ultrafast freezing technology and pre freezing embryo culture technology can improve the survival rate and survival rate of embryos. In terms of PGD technology, PGD technology based on whole genome sequencing can detect more genetic diseases and ensure more accurate and comprehensive embryo health.
Through these new breakthroughs, the success rate of IVF has been significantly improved, providing more hope and options for couples who cannot conceive naturally or suffer from specific reproductive disorders.
