Relevant technologies of IVF in China
IVF technology is a kind of assisted reproduction technology. It is a method to achieve fertility by cultivating fertilized eggs in vitro and then implanting healthy embryos into the mother. The technology of IVF is developing rapidly in China. The following will introduce the related technologies of IVF in detail from four aspects: embryo culture technology, embryo selection technology, assisted incubation technology and ion flow technology.
Embryo culture technology
Embryo culture technology is one of the core links of IVF, which plays a vital role in the development and selection of embryos. At present, the domestic embryo culture technology mainly includes two types: multicystic culture and continuous culture.
Polycystic culture is one of the most commonly used methods of embryo culture. It provides suitable temperature, nutrients and gas conditions for embryos by simulating the maternal internal environment, and promotes the normal development of embryos. At present, medical institutions such as Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University have adopted the technology of polycystic culture for IVF treatment.
Continuous culture technology is a new embryo culture method launched in China in recent years. It can realize the continuous monitoring and evaluation of embryos and improve the development rate of embryos. A reproductive hospital in Shenzhen has introduced the first continuous culture system in China, which improves the success rate of IVF through real-time monitoring of the morphology and metabolic status during embryonic development.
Embryo selection technology
Embryo selection technology is one of the key links of IVF technology. It can screen healthy embryos and improve the success rate of IVF. The commonly used embryo selection techniques in China mainly include embryo morphological evaluation and gene detection.
The evaluation of embryo morphology is one of the most commonly used embryo selection techniques at present. It judges the embryo with the most development potential by observing the development of the embryo in the culture process, the number of embryonic cells, cytoplasmic deviation and other indicators. Many medical institutions, such as Guangzhou Union Medical College Hospital and the First Affiliated Hospital of Chongqing Medical University, have adopted the embryo morphology evaluation technology for embryo selection.
Gene detection is a more accurate and advanced embryo selection technology, which can perform gene detection on embryos and screen out embryos carrying genetic diseases or gender selection. Beijing Obstetrics and Gynecology Hospital is one of the earliest hospitals to introduce gene detection technology in China, and has achieved good results in IVF treatment.
assisted hatching
Assisted incubation technology is an important means of IVF technology, which can provide a more ideal incubation environment and increase the pregnancy rate of IVF. At present, the commonly used assisted incubation technologies in China mainly include embryo adherent culture, embryo cell nutrient solution and active nutrient supplement.
Peking University People's Hospital and other medical institutions use the embryo attachment culture technology to attach embryos to the wall of culture dishes, providing a larger surface area and a more suitable nutritional environment, and promoting the development of embryos.
Ion flow technology
Ion flow technology is a new technology in IVF technology. It provides a more stable environment for embryos by adjusting the ion concentration and flow rate in the culture medium. A large domestic reproductive hospital introduced ion flow technology, which improved the quality of embryo development and pregnancy rate by increasing the ion concentration and flow rate in the culture medium.
Summary
After years of development, IVF technology in China has made many breakthroughs. Embryo culture technology includes multicystic culture and continuous culture, embryo selection technology includes morphological evaluation and gene detection, assisted incubation technology includes embryo adherent culture and nutrient supplement, and ion flow technology is an emerging technology. The continuous innovation and promotion of these technologies have brought hope and gospel to infertile patients.
