The effects of pH on European burbot spermatozoa motility at particular times after activation.

<p>(A) percentage of motile spermatozoa (MOT). (B) duration of motility. (C) curvilinear velocity (VCL). (D) linearity (LIN). (E) amplitude of lateral head displacement (ALH). (F) beat cross frequency (BFC). Values marked with the same letter are not significantly different from one another (P>0.05). Two-way or one-way ANOVAs and then Tukey tests were used for the post-hoc comparison. Mean value ± SEM.
