  • Motility is an essential characteristic of all fl agellated spermatozoa and assessment of this parameter is one criterion for most semen or sperm evaluations. (uwc.ac.za)
  • We used the Sperm Class Analyzer ® (SCA) CASA system to assess the total percentage of motile spermatozoa in a sperm preparation as well as the percentages of rapid, medium and slow swimming spermatozoa for six mammalian species. (uwc.ac.za)
  • The effects of medical treatments on sperm motility become apparent in changes in the distribution of spermatozoa among the three swimming speed classes. (uwc.ac.za)
  • The objective of the present studywas to evaluate the effects of pre-freezing sperm concentration (200,400 or 800x106 spermatozoa/ml) using two commercial extenders (Bioexcell® and Andromed®) on post-thaw survival and acrosomal status of ram spermatozoa. (ebscohost.com)
