An improved method for objective evaluation of results in the complement dependent sperm immobilization test, with the aid of the multiple exposure photography (MEP) method is described. With this method it is possible to determine the percentage of residual motility of spermatozoa quantitatively after incubation with sera suspected of having immobilizing activity in the presence of complement. Long term storage of information, reexamination of data and comparison of results after various treatment are routinely possible with this method.
