A review of available literature has shown something of a paucity of suggested and applied microscopic techniques on the identification of human spermatozoa in forensic casework. Phase contrast microscopy (PC) has been mentioned as the desirable technique by Kirk  and Kivela . The advantages of PC as compared with bright-field are well known and would most certainly include simplifying the task of locating any spermatozoa present. Some other advantages are an apparent improvement in the morphological detail presented to the observer and some reduction in the fatigue associated with the eyestrain accompanying this frequently tedious task.
