A fertilized egg develops into a blastocyst, then an embryo, then a fetus. How The Evewell grades embryos · Why do we grade embryos? · Features of an Embryo · Grading Day 3 Embryos · Grading Day 5 Embryos (Blastocysts) · Blastocyst Grading ... The blastocyst is a hollow cellular mass generated during early development and composed of cells forming the trophectoderm, the inner cell mass, and the fluid- ... Because embryos are developmentally different on these days, we have different grading systems for day 3 (cleavage stage) embryos and day 5 (blastocyst stage) ... The blastocyst consists of a layer of outer cells that eventually become the placenta, and a small number of inner cells, which will form the fetus. At this ... The aim of this study was to 1.
