To optimize the Hamilton-Thorn Motility Analyzer (HTM; Hamilton-Thorn Research, Beverly, MA) for use in reproductive toxicology studies with rat spermatozoa, the accuracy and precision of the instrument were assessed under a variety of instrument settings. Videotapes of both fast- and slow-swimming sperm were analyzed repeatedly to obtain data across a range of sperm velocities as might be encountered as a consequence of exposure to reproductive toxicants. Acquisition rates were varied across the HTM menu choices as were the number of frames analyzed at each framing rate. For fast-swimming samples (mean straight-line velocity (VSL) approximately 130 micrometers/sec) generally good agreement between computer-assisted sperm analysis (CASA) and manually obtained data was found for percentage of motile sperm and straight-line velocity; i.e., CASA values were within 10% of manual values for most frame/rate combinations.
