Three generations of IVF can conceive a dragon and phoenix child, but you can’t go through three generations of IVF to choose a dragon and phoenix child, from the legal level, the domestic ban on non-medical purposes of screening the gender of the embryo. Technically through the third generation of IVF can be more accurate in determining the gender of the embryo before transferring the embryo, and the success rate of twins is also higher, but it does not completely guarantee that all of the transferred twins survive, and it is not possible to determine whether or not the embryo undergoes mitosis at a later stage to form a triple or even a quadruple pregnancy. Third-generation IVF is technically capable of achieving dragon and phoenix twins, but they cannot be selected in China. China’s law stipulates that IVF prohibits gender selection, except in the special case that the probability of certain genetic diseases is obviously related to gender, and embryos of a certain gender are selected for transfer with the help of third-generation IVF technology. Third-generation IVF is suitable for patients with chromosomal abnormalities and genetic diseases with related genes, and through third-generation IVF, the genes that are inherited are screened out, so that the patient can give birth to a healthy child. It is recommended to go to regular hospitals for third generation IVF transplantation to increase the success rate of transplantation.
