To compare the frequencies for each score, we used the Z-statistic for independent proportions (Pearson). No significant differences were noted (P<0.05). Score 10, complete spermatogenesis, numerous sperm cells with organized germinal epithelium. Score 9, presence of many sperm cells with disorganized germinal epithelium. Score 8, presence of few sperm cells. Score 7, no sperm cells, but numerous spermatids. Score 6, no sperm cells, with few spermatids. Score 5, no sperm cells or spermatids, but numerous spermatocytes. Score 4, few spermatocytes. Score 3, only spermatogonia. Score 2, only Sertoli cells, no germ cells. Score 1, acellular seminiferous tubules.
