With the continuous development of IVF, the success rate of the third generation of IVF has reached 65%-75%, helping many infertile families to achieve their desire to have a baby, so why is the success rate so high? Today Hengjian Overseas will unveil this mysterious veil for everyone.
Third-generation IVF refers to the removal of one cell from a fertilized embryo and culture into multiple cells before undergoing cytogenetic or molecular genetic examination. Only if it is confirmed that the embryo does not have a genetic disease can the embryo be transferred to the mother's womb. Therefore, the conditions of the third generation of IVF are more stringent, which is mainly to be able to not only screen the patient's abnormal chromosomes, so as to avoid thalassemia, Down syndrome, cat barking syndrome and other genetic diseases affecting the fetus, to get a healthy baby, but also to be able to choose the baby's sex. This initiative has greatly improved the success rate of IVF, which can be said to be a blessing for infertility patients and second children who want boys or girls.
In addition, this technology supports the artificial selection of survival of the fittest, which is then transplanted into a woman's uterus with healthy, high-quality blastocysts. The good genes of parents are passed on to their children, and these good genes have stronger vitality than other genes, improving the survival rate of babies. Judging from the current data, the proportion of third-generation IVF families in China is increasing year by year. With the continuous development of science and technology, there will be more options.
The key to the success of the third-generation IVF is the laboratory, one of which is the embryo laboratory and the other is the PGS and PGD gene screening laboratory. Genetic screening will use the third generation of PGD technology, or third generation technology, from pre-TEST physical examination, ovulation induction, egg retrieval, embryo transfer to every step of the successful pregnancy. Embryo culture is a key part, so the embryo laboratory is mainly based on medical advanced personnel, thus ensuring the survival rate of its embryos.
