What is the clinical relevance of distinguishing spermatids from WBCs during a semen analysis?

February 29, 2016

Answer: Leukocytes, predominantly polymorphonuclear leukocytes (PMN, neutrophils), are present in most human ejaculates (Tomlinson et al., 1993; Johanisson et al., 2000). They can sometimes be differentiated from spermatids and spermatocytes in a semen smear stained with the Papanicolaou procedure. Differentiation is based on differences in staining coloration, and on nuclear size and shape (Johanisson et al.,…
