title: Cytochemical detection of hyaluronidase activity in single human and mouse sperm by an improved substrate-film technique.
abstract: A substrate-film method is described that allows the detection of hyaluronidase activity in nearly 100% of single human and mouse sperm. The level of hyaluronidase activity as determined by halo diameters was greater in mouse than in human sperm. This simple method may have use as a screening method for identifying compounds that cause developmental or genetic defects in male germ cells, or for the diagnosis of infertility due to decreased hyaluronidase activity.
