Representative pathological changes in ovaries: (A) control, (B) 0.005 mg/kg of T-2 toxin, (C) 0.05 mg/kg of T-2 toxin. The vaginal epithelium thickness: (D) control, (E) 0.005 mg/kg of T-2 toxin, (F) 0.05 mg/kg of T-2 toxin, and (G) measurement of vaginal epithelium thickness of mice offspring whose dams were orally administered with T-2 toxin at 0, 0.005, and 0.05 mg/kg from gestational day 14 (GD 14) to lactational day 21 (LD 21). Black arrows indicate the follicles are in secondary and antral stage in (A,B) and in (C) it indicates atretic follicles. Black lines in (D–F) indicate vaginal epithelium thickness. Scale bar: ovary 100 μm and vagina 50 μm.
