The embryos are still at the same size as an unfertilized 2020-04-07 · Embryo culture using sequential media In order to allow embryos make it to blastocyst stage, they are cultured in two media of different chemical composition to adapt to the nutritional requirements of embryos at each phase of their development. Embryos are cultured in the first medium from the zygote (day 1) stage until day 3. Because embryos are developmentally different on these days, we have different grading systems for day 3 (cleavage stage) embryos and day 5 (blastocyst stage) embryos. Each will be discussed in turn. Day 3 Embryo Grading: Quality of Division. Day 3 embryos are referred to as “cleavage stage” embryos.
