title: Light scattering determination of various characteristic paramenters of spermatozoa motility in a serie of human sperm.
abstract: In this paper are presented the results obtained by the light scattering method of systematic study of different parameters characterizing spermatozoa motility in a series of human sperms, one hour and five hours after ejaculation. These results are relative to the concentration of spermatozoa, the percentage and the number of motile spermatozoa, the characteristic velocity and the velocity distributions. All these parameters are discussed one by one, the advantages (objectivity, small quantity of not diluted sperm, short time needed for measurements) and the limits of the light scattering method being pointed out. A comparison is made with results obtained by conventional methods. The fineness of this study shows that this method can be used with success in fundamental research as well as in a routine functional sperm study, allowing an objective and precise analysis of motility in a given population as a complex factor.
