Flow cytometry is a powerful technique for measurements of many structural and functional cell parameters. In sperm analyses it offers several advantages over the formerly used methods: high accuracy, possibility of measuring two or even three parameters simultaneously and analysis of a high number of cells per second. Moreover, at present it is the only technique which allows sperm sorting of X- and Y-fractions with high purity. The paper is a review of the flow cytometry applications in sperm sexing and measurements of quality parameters: membrane integrity, acrosome status, mitochondrial and esterase activity and sperm chromatin structure.
