Technical characteristics and advantages of the third generation of test tube babies in China
With the continuous development of science and technology, domestic IVF technology is also constantly innovating. The third generation IVF technology is the latest IVF technology. Compared with the previous two generations, the third generation IVF technology has many unique characteristics and advantages. This article will elaborate on genetic screening, embryo culture, embryo screening and implantation regulation.
genetic screening
The third generation IVF technology has made a major breakthrough in genetic screening. Through high-throughput sequencing and gene identification technology, we can quickly and accurately analyze the embryos of patients with gene diseases, and select normal embryos for implantation. Compared with the traditional first and second generation technologies, the third generation IVF technology has achieved a qualitative leap in the accuracy and efficiency of genetic screening.
The IVF Center of the Capital Institute of Pediatrics is one of the first hospitals in China to introduce the third-generation IVF technology. Using gene amplification technology and Next Generation Sequencing (NGS) platform, they can simultaneously detect hundreds of loci, realize comprehensive genetic screening of embryos, and greatly improve the accuracy and reliability of screening.
Embryo culture
High quality embryo culture is one of the keys to the success of IVF technology. The third generation IVF technology has unique technical advantages in embryo culture.
Shanghai Ren'ai Hospital has made important innovations in embryo culture. They used the time resolved mother culture system (Time Lapse) technology, which can monitor the embryo division speed and quality development in a timely manner by continuously photographing the whole process of embryo culture, improving the stability of the embryo culture environment and the survival rate of embryos.
In addition, the Pediatric Hospital affiliated to Shanghai Jiaotong University also introduced tandem mass spectrometry, which can monitor the changes of new and old metabolites of embryos in the culture medium in real time, predict the quality of embryonic development in advance, and make more accurate judgments for implantation.
Embryo screening
Embryo screening is a key factor in the success rate of IVF. The third generation IVF technology uses advanced gene detection technology in embryo screening, which has obvious advantages.
The Children's Hospital affiliated to Zhejiang University School of Medicine has introduced the latest thousand gene screening technology, which can simultaneously detect hundreds of gene loci related to genetic diseases, and more comprehensively screen the genetic disease risk of embryos. This gene screening technology can also be used to screen for potential chromosomal abnormalities and genetic mutations, helping doctors select the healthiest embryos for implantation.
The IVF Center of Beijing Children's Hospital has introduced PGT-A (Preimplantation Genetic Testing for Aneuploid) technology, which can detect whether the embryo has abnormal chromosome number. This technology greatly improves the implantation rate and pregnancy success rate of implanted embryos by screening the chromosome structure of embryos.
Implantation regulation
The third generation IVF technology has also carried out innovative regulation in the process of embryo implantation.
The IVF Center of Peking Union Medical College Hospital has introduced PRP (Platelet rich Plasma) technology, which uses platelet suspension rich in growth factors to improve blood circulation and metabolism of the endometrium and create the most suitable environment for embryo implantation. This technique can significantly improve the success rate of embryo implantation and the sustainability of pregnancy.
The IVF Center of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology adopted minimally invasive implantation technology, which improved the success rate and survival rate of embryo implantation by precisely controlling the implantation site and angle. This technique can reduce the risk of endometrial damage and embryo transfer, and improve the success rate of IVF.
In conclusion, the third generation technology of IVF in China has significant technical characteristics and advantages in genetic screening, embryo culture, embryo screening and implantation regulation. The introduction of these innovative technologies provides more choices and hopes for infertile couples, and also improves the success rate and birth health rate of IVF.
Summary
