The general success rate of third-generation blastocyst implantation is 40% to 45%, but it depends on your own situation. According to the data of global research, the success rate of three-generation IVF is about 40% to 45%, and the live birth rate is 35%. If pre-implantation screening or diagnosis is done, there are relatively few cases of chromosomal abnormalities or other genetic abnormalities in embryos that lead to non-attachment or cessation of embryo development, so the success rate of three-generation IVF is higher than that of ordinary IVF. Higher-aged women have a higher chance of embryo abnormalities, so they may choose to undergo three-generation IVF for screening and related tests before implantation.
