What is the 'perfect' blastocyst grading score? A morphologically “perfect” day 5 embryo transfer would be a 4AA; good expansion and excellent inner cell mass ... Feb 2, 2022 ... A blastocyst is an embryo that is four to nine days after fertilization and consists of 100-200 cells in total and is about 1/10 of a millimetre ... Blastocyst transfers correlate with higher implantation rates. Blastocyst transfers are included in our IVF and ICSI Complete packages if medically appropriate.
