Sperm motility is an important indicator of male reproductive function. An automated computerized system was used to measure the movement characteristics of cynomolgus monkey sperm. Swimming velocities were in good agreement with data derived from tracking sperm heads manually with a digitizer, but sperm counting by the system was erroneous. In some ejaculates, there were two subpopulations of sperm with different curvilinear velocities, linearities of swim‐paths, and lateral movements of the heads.
