Figure 3: Scatterplot of logarithmic transformed ROS levels, showing each relationship between the ROS levels and sperm motion parameters measured by two CASA systems in ROS-positive group. (a) Sperm concentration; (b) motility; (c) VSL; (d) VCL; (e) LIN; (f) mALH; (g) BCF; (h) progressive motility. Circle plots expressed SMAS data and approximate lines were continuous. Triangle plots expressed CellSoft data and approximate lines were broken. Sperm concentration (P0 < 0.01; P < 0.01), motility (P < 0.05; P < 0.01), mALH (P < 0.05; P < 0.01), and progressive motility (P < 0.05; P < 0.01) showed inverse correlations with ROS level.
