Different superscripts within the same column indicate differences among groups (P < 0.05).
TM total motility, PM progressive motility, VSL straight–line velocity, VAP average path velocity, VCL curvilinear velocity, LIN linearity, STR straightness, ALH mean amplitude of the lateral head displacement, BCF mean of the beat cross frequency.
