Fig. 8From: External quality assessment scheme for sperm DNA fragmentation: a pilot study in ChinaA Dot plot with low speed for flow cytometry. At low speed, a single cell passes through the sample tube, and cells appear on a diagonal. B Dot plot with high speed for flow cytometry. At high speed, multiple cells pass through the sample tube at the same time, and the cells are clustered together in an off-diagonal distribution.
