How early can a blastocyst implant?
Implantation. Once the embryo reaches the blastocyst stage, approximately five to six days after fertilization, it hatches out of its zona pellucida and begins the process of implantation in the uterus.
At what stage is an embryo implanted in IVF?
IVF embryos are usually transferred on the second or third day after egg retrieval, at the four to eight-cell stage. The IVF embryos must continue to grow for two or three more days to reach the blastocyst transfer stage (100-150 cells) before they are ready for implantation into the uterine wall (endometrium).
