The success rate of 8-cell fresh embryo transfer for women is around 80%. Fresh embryo is the embryo in the cleavage stage that is transferred into the woman’s uterus after the woman’s egg is successfully paired with the male sperm and cultured in the laboratory for about a week to improve the embryo transfer success rate by increasing the number of embryos transferred. Eight cells are always among the more numerous cells and the success rate of fresh embryo transfer is lower once the cell count is less than three. The success rate is related to the number of cells and the quality of the embryos, or the environment and physical condition of the woman’s uterus. Before the transfer, women need to adjust their body condition to the best condition, and also strengthen the care after the embryo transfer to reduce the failure rate, pay attention to rest, avoid strenuous exercise, try to lie down and eat more protein-rich food, and do the corresponding examination to observe the fetal development.
