Sumario:This study was conducted to describe the stages of seminiferous epithelium (SE), determine the relative frequency of the stages, and identify the steps of spermatid development during spermatogenesis in the testicular tissue of Aceh bull. Seven pairs of the testicular organs of Aceh bull (Bos indicus) were used and then processed in a histological manner for staining using haematoxylin and eosin (H&E) and periodic acid-Schiff-haematoxylin (PAS-H). The stages of seminiferous tubules were examined using a tubular morphology method while spermatid development was observed based on the acrosome formation during spermatid development. Eight stages (stages I to VIII) of SE were found in the testicular seminiferous tubules of Aceh bull. Furthermore, the percentage of the relative frequency of each stage was 25.48, 15.38, 12.92, 4.74, 14.97, 10.69, 10.74, and 5.08%, respectively, with the relative frequency of premeiotic, meiotic, and postmeiotic phases being 53.78, 4.74, and 41.48%, respectively. Spermatid development from round to elongated spermatids occurred in 14 steps. Steps 1 to 7 were observed in stage I, steps 8 and 9 in stage II, steps 10 and 11 in stage III, step 12 in stage IV, step 13 in stages V and VI, and step 14 in stages VII and VIII. These findings can be used as a basis for further studies, particularly in evaluating the abnormality of the cellular composition of the seminiferous tubule in each stage of spermatogenesis and also in determining daily sperm production in Aceh bull.
