Patient's question:
My husband and I are using IVF. The doctor told us that the blastocyst quality is 5bc. Could you please tell me what the blastocyst quality 5bc means?Doctor's answer:
5bc is still decent, considered upper-mid level. The number represents the blastocyst grade, with 6 being the highest. Entering the 4th grade means there is a 40 to 60% pregnancy rate, while the 5th grade has a 50 to 60% pregnancy rate. The second letter represents the inner cell mass grade, with A indicating a higher number of cells, tightly arranged, and B indicating fewer cells, loosely arranged. The third letter represents the trophoblast grade of the placenta, with A indicating a dense upper cell layer composed of more cells, and B indicating a sparse epithelial cell layer composed of fewer cells.
