An electron micrograph of sections of testis of MSG-treated rats showing a vacuolation in spermatogenic cells (v), autolysis in spermatogonia (Sg) and primary spermatocytes (Ps) with damaged nucleus and fragmented chromatin (arrows) (scale bar = 2 µm), b Sertoli cell (Sc) and primary spermatocytes (Ps) with vacuolation (v) (scale bar = 2 µm), c spermatids (Sd) with active lysosomes (Ly), degenerated nucleus and marked decrease in number of sperms (Sp) in lumen (L) of seminiferous tubules (scale bar = 2 µm) and (e) Lydeig cells with abnormal nucleus and vacuolation (v) (scale bar = 2 µm)
