There is no such thing as genetic incompatibility, and it can only be said that some of the genetic diseases or chromosomal abnormalities with known disease-causing genes can be successful by doing the third generation of IVF. The third generation of test tube technology is mainly for the already known disease-causing genes of genetic diseases or chromosomal structural abnormalities, such as hemophilia, serosanguineous disease, ichthyosis, etc. Through the third generation of test tube technology can be screened genetically, so as to effectively avoid the above mentioned diseases, thus enhancing the success of pregnancy. However, for genetic diseases with unknown causative genes and genetic diseases caused by multiple genes, there is no way to screen through the third generation IVF technology, although pregnancy can be successful, but it is prone to miscarriage and health problems. Third-generation IVF technology can help improve many problems, but whether it is suitable or not should follow the guidance of professional doctors.
