How does IVF Work?

The cleavage-stage is after 3-4 days from fertilization, and the blastocyst stage is done after a week of fertilization when the embryo has reached the optimal growth level. The implantation of the embryo in the uterine walls is done within the next six to twelve days leading to a successful pregnancy conception.
