The success rate of transferring an 8-cell embryo, which is one of the more multicellular embryos, is relatively high, but the exact success rate is related to the woman’s health condition and the quality of the embryo. When an embryo at the cleavage stage is transferred into a woman’s uterus, the transfer success rate is higher when the number of cells transferred from the embryo is higher. 8-cell embryos are more multicellular embryos, and the transfer success rate is higher. However, the specific transfer success rate is related to many factors, such as the number of cells in the embryo, the quality of the embryo, the woman’s physical condition, and the woman’s intrauterine environment. Before the embryo transfer, a woman can improve her health condition to the best state to increase the success rate of the embryo transfer. In addition, after embryo transfer, women should pay attention to rest, avoid strenuous exercise, take more food rich in vitamins and proteins, and have regular checkups to observe the development of the fetus.
