a,b. Means within a row with different letters are significantly different. 1 VOL, sperm volume; CONC, sperm concentration; TSO (VOL*CONC), total sperm output; SMI, sperm membrane integrity; TMS, total motile sperm; PMS, progressive motile sperm; VCL, curvilinear velocity; VSL, straight-line velocity; VAP, average path velocity; LIN (VSL/VCL × 100), linearity; STR (VSL/VAP × 100), straightness; WOB (VAP/VCL × 100), wobble; ALH, amplitude of lateral head displacement; BCF, beat cross frequency. ns = not significant.
