New technology of the third generation of IVF
In recent years, with the continuous progress of science and technology, IVF technology is also constantly innovating and developing. The third generation of IVF technology covers many new technologies and methods, providing more possibilities for those infertile couples to realize their reproductive dreams. This article will elaborate on the new technologies of the third generation of IVF in terms of genetic screening, hormone therapy, embryo culture and assisted incubation.
genetic screening
In the third generation technology of IVF, genetic screening plays a crucial role. The traditional genetic screening mainly uses amniocentesis or villus biopsy to obtain the genetic information of embryos, but these methods are highly invasive and risky. Now, with the help of gene chip technology, we can screen genetic diseases of embryos through non-invasive blood or amniotic fluid testing. The rapid development of this technology enables infertile couples to more accurately select healthy embryos for IVF.
In addition, the application of new generation gene sequencing technology also provides more options for genetic screening in IVF. By sequencing the whole genome of the embryo, we can find some gene mutations that are difficult to detect by conventional genetic screening methods, thus improving the accuracy and breadth of embryo screening.
At present, many internationally renowned reproductive hospitals are using these new genetic screening technologies, such as the Reproductive Medicine Center affiliated to Harvard University School of Medicine in the United States and the London IVF Center in the United Kingdom.
hormone therapy
Hormone therapy has always played an important role in IVF technology. The third generation of IVF technology has significantly improved the success rate of patients through the application of new hormone therapy.
First, through the use of improved ovulation promoting drugs, we can accurately control the time and number of patients' eggs, and improve the quality of eggs in the transplantation cycle. Secondly, the use of new progesterone preparations can better maintain the stability of endometrium and improve the implantation rate of embryos. In addition, the new hormone treatment scheme can also reduce the side effects of patients and improve the effect of individualized treatment.
These new hormone therapy technologies have been widely used in reproductive hospitals in many countries around the world, such as the California Reproductive Medical Center in the United States and the Tsinghua Bauhinia Test Tube Baby Hospital in China.
Embryo culture
Embryo culture is a very important part of IVF technology. In the third generation of IVF technology, new technologies on embryo culture are emerging in endlessly.
First of all, the new generation of embryo culture incubators can simulate the environment in the mother's womb and provide more suitable conditions for the growth of embryos. Accurate control of environmental factors can improve embryo quality and implantation rate. Secondly, some reproductive hospitals have begun to use continuous culture technology, that is, put the fertilized eggs into a special incubator for continuous culture, which avoids the interference of frequent inspection on embryonic development and improves the survival rate of embryos. In addition, the use of liquid culture media also provides a better environment for embryo culture.
It is worth mentioning that the Melbourne IVF Institute, a famous Australian reproductive hospital, has always been in a leading position in the field of embryo culture.
Assisted Hatching
Assisted incubation technology has also been widely used in the third generation of IVF technology. Conventional IVF technology requires embryos to develop in the chamber or incubator during the process of embryo culture. The assisted incubation technology is to transfer embryos to the patient's body for development, simulating a more natural incubation environment.
This technology can improve the survival rate of embryos, promote the interaction between embryos and endometrium, and facilitate embryo implantation. In addition, the patient's internal environment can also provide better conditions for embryo growth and improve the implantation rate. The emergence of assisted incubation technology has brought new breakthroughs to the success rate of IVF technology.
In general, the third generation technology of IVF has made important progress in genetic screening, hormone therapy, embryo culture and assisted incubation. The application of these new technologies has led to a higher success rate of IVF technology and a wider range of choices, bringing more hope to infertile couples.
