title: A new method for rapid spermatozoal concentration and motility: a multiple-exposure photography system using the Polaroid camera.
abstract: A multiple exposure photography (MEP) system using the Polaroid camera PM-CP (Olympus, Tokyo, Japan) has been developed to accurately estimate the concentration and motility of spermatozoa in routine clinical work for the treatment of infertility. This Polaroid-MEP system is equipped with a xenon stroboscope MS-230 (Sugawara Laboratories Inc., Tokyo, Japan), and Makler's Counting Chamber (Sefi-Medical Instruments, Haifa, Israel). The system immediately produces printed images of spermatozoal tracks at the laboratory of the outpatient clinic, providing objective and exact information about the concentration and the motility of spermatozoa.
