Abstract Background Several studies have been published where sperm plasma membrane integrity correlated to fertility. In this study we describe a simple fluorometer-based assay where we monitored the fluorescence intensity of artificially membrane-ruptured spermatozoa with a fixed time staining with fluorescent DNA dyes. Methods Membrane-impermeant fluorescent dyes Hoechst 33258 H258 and propidium iodide PI were used to measure the fluorescence of the nucleus in artificially membrane ruptured spermatozoa and membrane-permeant dye Hoechst 33342 H342 was used to measure fluorescence of intact spermatozoa. The concentration of spermatozoa in insemination doses varied from 3l.2 X l06 ml to 50 X l06 ml and the average value was 35 X l06 ml. Each boar .
