Fig 3. Photomicrographs of ovarian sections stained by hematoxylin and eosin.

(A)& (B): histological sections from control ovaries shows normal histopathological structure with multiple follicles of different stages (black arrows), intact oocytes (O) and granulosa cells (g). (C)& (D): γ- irradiated ovarian sections shows few, if any, healthy follicles (arrows) with hemorrhage in the cortex (circle). Many small primary follicles are atretic (a) with degenerating oocytes and granulosa cells in irradiated ovaries. (E)& (F): GH-irradiated ovarian sections shows similar organization to the control group. (G) & (H): ovaries from animals treated with GH alone shows multiple growing follicles (arrows) with intact oocytes (O) and granulosa cells (g). Scale bar, 20 μm. gf: Graffian follicle, S: Stroma.
