not appear to act "normally". Most reports indicate (Huat, 1975; Smith, 1978) an average motility score of 85%. Semen with an initial motility much below this should probably not be processed any further. MORPHOLOGY When sperm morphology is evaluated (Fig. 5), one usually looks for abnormal shapes of the head and tail. It has become popular to examine the morphology of a portion of the head, the acrosome. Examination of the acrosome requires the use of a fairly sophisticated microscope fitted with either phase-contrast or differential interference optics. Even though researchers find measurement of acrosomal integrity helpful, most bull studs to do not perform this evaluation because of the time and expense in making this measurement.
