How to do the third generation IVF
In recent decades, IVF technology has undergone three generations of evolution. The third generation of IVF technology has made a significant breakthrough, which has realized the dream for many infertile couples. The following will elaborate on the practices of the third generation of IVF from four aspects: embryo selection, embryo culture, embryo transfer and innovation of assisted reproductive therapy.
Embryonic selection
Embryo selection is to select the most potential embryos for transfer through a series of means. In the third generation of IVF technology, embryo selection has been strengthened and improved. First, through gene sequencing technology, doctors can conduct genome testing on embryos to screen out embryos carrying genetic diseases or chromosomal abnormalities and avoid inheritance of genetic diseases. Secondly, the new time period culture system can monitor the development of embryos in different culture periods, and further determine the quality and development potential of embryos.
In real hospitals, such as Beijing Tongren Hospital Reproductive Medical Center, doctors will select the best embryos for transplantation according to the results of the embryo genome testing and time period culture system, so as to improve the success rate of IVF.
Embryo culture
Embryo culture refers to placing fertilized eggs in a specific culture medium to provide a suitable environment for their normal development. The third generation IVF technology has made innovations in embryo culture. Traditional embryo culture is usually carried out in the incubator, which is vulnerable to environmental factors such as temperature and humidity. In the third generation of IVF technology, the closed cell culture system is used to provide a more stable culture environment and avoid external interference.
In addition, there is an innovative way of embryo culture - continuous culture system. The system can monitor and control the nutrient concentration and PH value in the culture medium in real time to ensure that the embryo develops in the most suitable environment. Due to the application of these new technologies, the quality of embryo development has been greatly improved.
embryo transfer
Embryo transfer is the core and final step of IVF technology. In the third generation of IVF technology, embryo transfer has become more accurate and efficient. Traditional embryo transfer is usually to transfer multiple embryos at one time, but it is easy to increase the risk of multiple pregnancy and abortion. In the third generation technology, doctors will select the best one or two embryos for transfer according to the quality and development of the embryos, making the transfer process safer and more successful.
In addition, in the assisted reproductive treatment, there are also new auxiliary technologies, such as vitrification of embryo endometrium and ultrasound guided embryo transfer. The application of these technologies can help doctors accurately determine the location and location of embryos, and improve the accuracy and success rate of transplantation.
Innovation of assisted reproductive therapy
In addition to innovations in embryo selection, embryo culture and embryo transfer, the third generation IVF technology has also made innovations in other aspects of assisted reproductive therapy. For example, in the egg retrieval technology, the traditional method of egg retrieval is needle aspiration under the guidance of ultrasound, while in the third generation technology, minimally invasive surgery can be used to remove eggs to reduce the pain and trauma of patients.
In addition, new fertility promoters have emerged in the third generation technology, such as LH drugs and sperm activating fluid. The application of these new drugs can improve the probability of pregnancy and help infertile couples achieve their fertility aspirations faster.
summary
The third generation of IVF technology has significantly improved the success rate and safety of IVF technology through the innovation of embryo selection, embryo culture, embryo transfer and assisted reproductive treatment. In real hospitals, such as the Reproductive Medicine Center of Beijing Tongren Hospital, the third-generation IVF technology has been successfully applied, which has helped many infertile couples realize their dreams of childbirth.
In general, the development of the third generation of IVF technology has brought new hope and choice to infertile couples and provided them with more opportunities to achieve healthy reproduction.
