There is no authoritative clinical data to show what the success rate of third generation IVF blastocyst transfer is, but most people have a higher success rate. Third-generation IVF blastocyst transfer is also known as pre-implantation genetic diagnosis/screening, which is mainly used for single-gene related genetic diseases, chromosomal disorders, and high-risk groups who may give birth to children with abnormalities. There is no authoritative data on the success rate of the procedure for the time being, but the general population has a high success rate of the procedure in order to reduce or avoid the harm to the mother that prenatal diagnosis during pregnancy may lead to induced labor. At the same time, preimplantation genetic diagnosis/screening also helps to improve clinical pregnancy rates and reduce multiple pregnancies. Since preimplantation genetic diagnosis/screening is not a substitute for prenatal screening, those who are found to have fetal abnormalities during routine prenatal checkups need to undergo other tests for clarification. It is recommended that those in need should visit regular hospitals for a comprehensive examination and undergo the surgery after evaluation by the doctor. After the surgery, both husband and wife should pay attention to keep their body and mind happy, get enough sleep, etc. Avoid strenuous exercise and intake of spicy and stimulating food in order to prevent lowering the success rate of the surgery.
