Abstract
Giemsa and Bryan-Leishman smear staining techniques have been quantitatively evaluated for their ability to determine round cells in human semen. Samples of fertile and vasectomy ejaculates were compared against counts obtained from semithin Araldite sections stained with toluidine blue. TEM studies and immunogold staining of the Pradite section permitted identification and quantitation of nucleated cell profiles. Differential counts from each of the three stains on the same set of semen samples were compared using regression analysis. Counts of seminiferous tubule elements from stain to stain correlated well (r> 0.9). Numerical analyses indicated, however, that leucocytes were commonly misidentifled. The r values for neutrophils were less than 0.8 and as low as 0.55 for lymphocytes. These low correlations presumably were due to failures to distinguish between these cells and seminiferous tubule elements.
