    Abstract:
    The motility characteristics of spermatozoa from asthenozoospermic semen were investigated and compared to the same parameters in fertile semen. The motility characteristics assessed by the CellSoft semen analyser (CRYO Resources Ltd, NY) were the following: curvilinear velocity (VCL), straight line velocity (VSL), amplitude of lateral head displacement (ALH), linearity (%LIN), and beat cross frequency (BCF). Analysis of the data indicated a decreased kinetic activity in the spermatozoa from the asthenozoospermic group which is expressed as a highly significant decrease (P < 0.002) in the VCL and VSL compared to velocities from normospermic samples. Moreover, percentage linearity and ALH were also statistically lower (P < 0.05) in this group. However, no difference was evidenced for the BCF.
