Figure 2. Histological sections of testes (a,b) and epididymis (c,d) of Cryptotis tamensis. Images (a) and (c) show a reproductive male with abundant sperm in the luminal edge of the seminiferous tubules and in the lumen of its epididymis, and (b) and (c) show a non-reproductive male with only basal cells in the spermatic epithelium and empty, almost obliterated epididymis. Spermatozoids: circle, solid line; Sertoli cell: white arrowheads; spermatogonia: black arrowheads; primary spermatocytes: circle, dashed line. Scale bars represent 150 μm.
