Effect of prenatal exposure to DEHP on the presence of ovarian cysts and ovarian endosalpingiosis. The photographs show histological sections of ovaries from 1-year-old mice in the F1, F2, and F3 generations. In the F1 generation, ovaries from (A) control and (B) 750-mg/kg/d treatment groups. In the F2, ovaries from (C) control and (D) 200-µg/kg/d treatment groups. In the F3 generation, ovaries from (E) control and (F) 500-mg/kg/d treatment groups. The black arrows indicate a cyst. The endosalpingiosis from an ovary treated with 20 µg/kg/d is shown at (G) ×10 and (H) ×40 original magnification.
