New technologies in the field of IVF in China
In recent years, with the development of science and technology and the progress of medicine, many new technologies have emerged in the field of IVF in China. These technologies not only improved the success rate of IVF, but also solved some problems that could not be solved before. The following will elaborate on the new technologies in the field of domestic IVF from four aspects: embryo screening, embryo culture, embryo implantation and frozen embryo protection.
Embryo screening technology
Embryo screening technology is to select the most viable and high-quality embryos for implantation through evaluation and screening of IVF embryos. Traditional embryo screening mainly depends on embryo shape, cell number and other indicators, but this method can not accurately determine the genetic status of embryos. In some advanced hospitals in China, such as Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine, gene detection technology has been introduced, that is, through gene sequencing of embryos, embryos free of genetic diseases and chromosomal abnormalities have been screened, which has improved the success rate of IVF.
In addition, some hospitals are researching and developing new embryo screening technologies, such as using artificial intelligence algorithms to evaluate embryos, judge the development of embryos more accurately, and provide more options for successful implantation.
Embryo culture technology
Embryo culture technology is to improve the survival rate and development ability of embryos by optimizing the embryo culture environment. The traditional embryo culture is usually carried out in a culture dish, but this method can not simulate the stability of the intrauterine environment, which is easy to cause embryo development obstruction.
To solve this problem, some hospitals have introduced dynamic training systems, also known as continuous training systems. This system can simulate the changes of temperature, pH value and oxygen concentration in the uterine environment, provide a more stable growth environment for embryos, and improve the survival rate and development quality of embryos.
In addition, some hospitals are also researching and exploring new embryo culture technologies, such as using stem cells to culture embryos, and promoting the development and maturation of embryos through the regulation of stem cells.
Embryo implantation technology
Embryo implantation technology refers to the implantation of high-quality embryos into the mother's uterus to realize the pregnancy and delivery of test tube babies. Traditional embryo implantation usually adopts blind implantation, which can not accurately determine the location and success rate of embryo implantation.
In order to improve the accuracy and success rate of embryo implantation, some hospitals have introduced 3D ultrasound guided embryo implantation technology. By using 3D ultrasound equipment to accurately locate and observe the position of embryos in the uterus, problems that may affect embryo implantation can be found in advance to avoid implantation failure.
In addition, some hospitals are still researching and trying new embryo implantation technologies, such as embryo implantation under microscope, to improve the accuracy and success rate of operation.
Frozen embryo protection technology
Frozen embryo protection technology refers to the technology of cryopreservation of embryos to prolong the survival and use time of embryos. The traditional frozen embryo protection mainly adopts liquid nitrogen freezing method, which has the problems of low freezing recovery rate and low survival rate of frozen thawed embryos.
To solve these problems, some hospitals have introduced new frozen embryo protection technologies, such as electronic freezing and nitrogen freezing. Electron freezing is to use electron beam irradiation instead of liquid nitrogen to freeze embryos, which can improve the freezing recovery rate and the survival rate of frozen thawed embryos. Nitrogen freezing is to use nitrogen to replace liquid nitrogen for embryo freezing, so as to reduce the oxidative damage of embryos during freezing.
To sum up, new technologies in the field of IVF in China mainly focus on embryo screening, embryo culture, embryo implantation and frozen embryo protection. The introduction and application of these new technologies not only improve the success rate of IVF, but also bring more hope and possibility to infertile patients.
