Blastocyst quality scoring based on morphologic grading correlates with cell number Koji Matsuura, Ph.D., Nobuyoshi Hayashi, M.D., Ph.D., Chisato Takiue, B.S., Rei Hirata, B.S., Toshihiro Habara, M.D., Ph.D., Keiji Naruse, M.D., Ph.D. Fertility and Sterility Volume 94, Issue 3, Pages 1135-1137 (August 2010) DOI: 10.1016/j.fertnstert.2009.11.003 Copyright © 2010 American Society for Reproductive Medicine Terms and Conditions

Figure 1 (A) Gardner scoring versus a scatter plot of the actual cell numbers of embryos. Numbers in circles are expansion rate. Morphology rates (A, B, and C) are outside of the horizontal axis. (B) Correlation of log2(BQS) and log10 of the blastocyst cell number (P<.0001). BQS = blastocyst quality scoring.
