In the last decade, clinics have learned how to grow embryos to a more advanced stage, known as “ Blastocyst ” — a stage when the embryo has developed at least 60 to 100 cells, and has differentiated parts that can be identified as an inner cell mass (the future fetus) and an outer layer (known as the trophectoderm) which is the future placenta.
