For the success rate of the third generation IVF, the key is the laboratory, one of which is the embryo laboratory, and the other is the PGS and PGD gene screening laboratory. Gene screening will use the third generation PGD technology, that is, the third generation technology, from pre-test tube physical examination, detection of ovum ovulation promotion period, egg retrieval, embryo transfer to successful pregnancy. Experts in this field are all engaged in embryo culture, and the embryo laboratory is mainly composed of medical students and advanced medical students, which ensures the survival rate of embryos from operators.
The third generation of IVF refers to taking out a cell from an embryo that has been fertilized and cultured to 8 cells for cytogenetic or molecular genetic examination. Only when it is confirmed that the embryo has no hereditary diseases can it be transplanted into the mother's uterus. Therefore, the conditions of the third generation of IVF are more stringent. Not only are there more and more screening procedures, but the screening targets are also upgraded to whether the couple has abnormal chromosome numbers and structural diseases. Therefore, we can know whether all the 24 chromosomes of the embryo are normal, and then use PGD technology to detect the genes of the embryo, diagnose whether the embryo is abnormal, and determine whether the embryo carries gene mutations that may cause specific diseases, so as to avoid the influence of genetic diseases such as thalassemia, Down syndrome and meow syndrome on the fetus. This greatly improved the success rate of IVF. It can be said that it is the gospel of infertile patients.
In addition, this technology supports artificial selection of survival of the fittest, and then healthy and high-quality blastocysts are transplanted into women's uterus, and the excellent genes of parents are passed on to their children. These excellent genes have stronger vitality than other genes, which improves the survival rate of babies. Judging from the current data, the proportion of families doing the third generation of IVF in China is increasing year by year. With the continuous updating and development of technology, there will be more choices. The medical expenses of the third generation IVF are generally around100000, and the success rate is around 75%. Technology is also in the forefront, and the relevant procedures are not complicated, the process is fast, and the success rate is high.
