A simple stain for differentiating semen constituents

Extensive use of Sedi-stain in an outpatient infertility office has demonstrated that this commercially available urinary sediment preparation is a valuable and practical stain in semen analysis. The stain is inexpensive, has a long shelf life, is easy to apply, and produces immediate and reproducible results. The accuracy of Sedi-stain has compared favorably to other staining compounds used. It should prove to be an asset to the office investigation of male infertility.
