There is no exact survival rate for grade 3 fresh embryos, and the survival rate is low compared to grade 1 and 2. Embryo transfer is categorized into four grades according to the quality of the embryo. Grade 1 and 2 fresh embryos have a regular appearance, the right number of cells, uniform size, less fragmentation, and high growth potential, while grade 3 fresh embryos have a relatively low growth potential, but are not incapable of development. The survival rate of grade 3 fresh embryo transfer is not exact. If the embryo can normally implant in the uterus and grow normally after the transfer, the transfer can be successful, but the chance of success is a little lower compared to grade 1 and 2 embryos. Embryo transfer try to visit a slightly larger hospital, choose a higher grade embryo transfer, and make sure the recipient is in good health, such as stable blood pressure and blood sugar, in order to achieve the expected results as much as possible.
