title: Cytometry of deoxyribonucleic acid content and morphology of mammalian sperm.
abstract: Because spermatogenesis is exquisitely sensitive to external influences, sperm can serve as a biological dosimeter. Advances in interpreting induced sperm abnormalities require a better understanding of sperm characteristics. This report reviews the application of several methods for automated, quantitative detection of shape changes, methods that are faster and more sensitive than conventional subjective techniques. Variability of sperm deoxyribonucleic acid content as a bioassay of genetic damage is explored, and limitations of the bioassay are discussed. New flow cytometric techniques that could lead to sexing mammalian sperm are examined.
