The successful implantation of a grade 3 embryo has the possibility of a successful birth, but of course, there is also the possibility of failure, whether or not it can be successfully born depends on the physical condition of the pregnant woman and the development of the embryo. 1. Can be born successfully: under normal circumstances, grade 3 embryo belongs to the relatively poor quality of the fetal sac, if the grade 3 embryo successfully implanted, the woman can carry on the pregnancy normally, when the woman does not have any abnormal stimulation or reaction after the embryo implantation, and the embryo development rate is relatively normal, it is possible that it will be born successfully. 2. Failure to give birth: However, if the woman’s body experiences serious rejection or abnormal reaction after the successful implantation of the third-degree embryo, which triggers unstable hormone levels in the body, it will also lead to developmental disorders of the embryo. Even if the third-degree embryo is successfully implanted, the pregnancy and the development of the embryo may still be affected, and in serious cases, the transfer may fail. In clinical practice, after the third-degree embryo has been successfully implanted, it is recommended that regular checkups be performed at the hospital.
