(a) and (b) Immature phase: germinal epithelium showing a reduced number of primary spermatogonia (Sg1). (c) and (d) Preparatory phase: presence of lots of primary spermatogonia and cysts of secondary spermatogonia (Sg2). Mitotic figures are also observed in this phase, highlighting the spermatogonial proliferation (arrow).
