ABSTRACT

A method combining Janus green B and Thymol blue stains the anterior part of the head, the nuclear membrane, middle piece, and tail of spermatozoa light green and the nucleus deep purple. The method provides excellent stained preparations for the evaluation of sperm morphology by phase contrast microscopy. It produces significantly less abnormal spermatozoa compared with the Papanicolaou stain.
