Diagram illustrating the 10 stages of the seminiferous epithelial cycle (SEC) characterized in the collared peccary based on the acrosomic system. The relative stage frequencies are also shown at the bottom (mean ± SD). Roman numerals indicate the 10 different stages of the SEC. The following germ cell types are depicted: Aund spermatogonia (As, Apr, and Aal), differentiated type A (A1, A2, A3, and A4), In, and type B spermatogonia. Arabic numerals (1–16) indicate each step of the spermatid acrosome (red) development in the collared peccary. D, diplotene; L, leptotene; M/2, meiotic figure and secondary spermatocyte; P, pachytene; Pl, preleptotene; Z, zygotene.
