KINETIC ACTIVITY OF SPERMATOZOA FROM FERTILE SUBJECTS AND ASTHENOZOOSPERMIC INFERTILE PATIENTS

The motility characteristics of spermatozoa from asthenozoospermic sem en were investigated and compared to the same parameters in fertile se men. The motility characteristics assessed by the CellSoft semen analy ser (CRYO Resources Ltd, NY) were the following: curvilinear velocity (VCL), straight line velocity (VSL), amplitude of lateral head displac ement (ALH), linearity (%LIN), and beat cross frequency (BCF). Analysi s of the data indicated a decreased kinetic activity in the spermatozo a from the asthenozoospermic group which is expressed as a highly sign ificant decrease (P<0.002) in the VCL and VSL compared to velocities f rom normospermic samples. Moreover, percentage linearity and ALH were also statistically lower (P<0.05) in this group. However, no differenc e was evidenced for the BCF.
