Figure 1: Motility (a) and curvilinear velocity or VCL (b) of B. splendens sperm exposed to negative control conditions or one of three doses of gadolinium (25, 50, or 100 μM). Sperm motility data were arcsin transformed prior to analysis. and . VSL and VAP (not shown here; see text for descriptions) were similar in statistical significance to VCL ( for both).
