title: Use of a microcomputer in combination with the multiple exposure photography technique for human sperm motility determination.
abstract: An inexpensive microcomputer system that serves as an accessory part of the multiple exposure photography technique for determination of sperm motility is described. With this system the percentage of motile spermatozoa, the average velocity, the frequency distribution of the velocities and the sperm concentration can be computed easily from 200 to 400 images of photographed spermatozoa and within 5 to 8 minutes. In this way the multiple exposure photography technique can be used widely in those centers that are interested in an objective and accurate method for determination of sperm motility in routine semen analysis and for research purposes.
