Abstract
A new staining method for differentiating WBCs from immature germ cells in seminal fluid has been studied. It is a combination of Bryan's sperm stain, which particulary stains the acrosomal cap of the spermatozoa and the spermatid, and Leishman's blood stain which stains the WBCs in the same way as found in blood smears. The peroxidase positive granules in the cytoplasm of the PMN leukocytes are seen clearly. Thus, it is possible to differentiate PMN leukocytes from non-separated spermatids when they are present in a common cytoplasm. The staining of acrosomal cap permits differentiation between spermatids and lymphocytes.
