The mean mature spermatid count (MMSC) provides a useful, simplified quantitative evaluation of human spermatogenesis that is based on the number of mature spermatids in histological sections of testicular biopsies. Here, the activity of the acid-fast (AF) stain was compared to that of the usual hematoxylin and eosin (H&E) stain in performing the MMSC. Thirty bilateral testicular biopsies showing normal spermatogenesis were chosen retrospectively from 15 subfertile patients with obstructive azoospermia or severe oligospermia. The MMSC was determined on each biopsy by utilizing both H&E and AF stains. The AF stain proved to be specific for the mature spermatids normally counted for the MMSC. It simplified recognition of mature spermatids, thereby shortening the overall time required for the procedure. The mean AF MMSC was lower than the mean H&E MMSC, and the mean interobserver differences were decreased. The AF stain is a superior stain for the MMSC when used in conjunction with the H&E stain for descriptive histology.
