  1. *Spermatozoa incubated without BRET-QD (1 nM). N = number of independent replicates; 1Total motility of spermatozoa; 2Proportion of sperm moving at a speed ≥ 30 μm/sec. Velocity data correspond to the average path (VAP), curvilinear (VCL), and straight-line (VSL). Data are mean ± s.e.m. and superscripts (a,b) indicate significant differences within the same column.
