Figure 2: (a–c) A photomicrograph of control testis showing (a) negative cytoplasmic immunostaining for caspase-3 (caspase-3 ×400); (b) positive proliferating cell nuclear antigen (PCNA) immunostaining (deep brown nuclear reaction) in most nuclei of the basal germ cells (PCNA ×400); (c) intense androgen receptor (AR) nuclear immunoexpression (brown nuclear staining) in the interstitial cells (I), myoid cell (M), and some sertoli cells (R) (AR ×400). (d–f) A photomicrograph of omega-3-treated testis showing (d) seminiferous tubules containing different germ cells with numerous spermatozoa (S) in the lumen. Notice the interstitial cells of Leydig (I) in-between the tubules (H and E ×200); (e) positive PCNA immunostaining basal germ cells nuclei (PCNA ×400); (f) intense androgen receptor (AR) nuclear immunoexpression in the interstitial cells (I), myoid cell (M), and most sertoli cells (R) (AR ×400).
