Forward progression of spermatozoa. Standardization of results.
The principal aim of this study was to determine whether subjective estimations of sperm velocity in our laboratory could readily be translated into objective figures. The technique for measuring the progression of human spermatozoa in seminal plasma in objective fashion was the one used by Janick and MacLeod in 1970. We therefore compared our objective figures with those of these authors and found a remarkable correlation between their values and ours. However, we went a step further and standardized the different objective values found in the study. Three simple equations were determined, by means of which each laboratory will be able to standardize their subject scale for forward progression of the spermatozoa.
