In study 2, the effect of extended IVC on the motility of testicular sperm was tested at three different incubation temperatures (21, 30, and 37 °C). The four types of motility (graded: I–IV) are graphically shown in stacked columns measuring the total motility at each of four intervals. Differences (p < 0.05) within each column between treatments are reflected by subscript differences adjoining the total motility value. Significant changes in motility patterns between intervals within incubation treatments are indicated by the inclusion of a directional arrow
