a, b Sperm trajectories before (a) and after (b) treatment with 25 μM Bay117082, as recorded by CASA. cj Changes in sperm motility parameters after treatment with 25 μM Bay117082 for 10 min. VCL, VAP, VSL, LIN, STR and WOB are presented in radar charts. ALH is shown in bar graphs. cf Bay117082-induced changes in parameters related to the motility of normozoospermic (c, d) and asthenozoospermic (e, f) sperm, with basal VCL ≤ 100 μm/s. gj Bay117082-induced changes in parameters related to the motility of normozoospermic (g, h) and asthenozoospermic (i, j) sperm with basal VCL > 100 μm/s. *p < 0.05; **p < 0.01; ***p < 0.001, as compared with the control (0 μM).
