Effects of prenatal exposure to the phthalate mixture on fertility indices at 11 months of age in the F1 generation of female mice. Breeding was monitored by examining mating index (panel A: control = 10 females/treatment group, 20 µg/kg/day = 8 females/treatment group, 200 µg/kg/day = 9 females/treatment group, 200 mg/kg/day = 9 females/treatment group), pregnancy rate (panel B: control = 10 females/treatment group, 20 µg/kg/day = 8 females/treatment group, 200 µg/kg/day = 9 females/treatment group, 200 mg/kg/day = 9 females/treatment group), fertility index (panel C: control = 10 females/treatment group, 20 µg/kg/day = 8 females/treatment group, 200 µg/kg/day = 9 females/treatment group, 200 mg/kg/day = 9 females/treatment group), gestational index (panel D: control = 9 females/treatment group, 20 µg/kg/day = 6 females/treatment group, 200 µg/kg/day = 6 females/treatment group, 200 mg/kg/day = 7 females/treatment group), and females who gave birth (panel E: control = 10 females/treatment group, 20 µg/kg/day = 8 females/treatment group, 200 µg/kg/day = 9 females/treatment group, 200 mg/kg/day = 9 females/treatment group). Graphs represent mean percentages in the F1 generation at 11 months. Carets (^) indicate borderline significance compared to the control (0.05 < P < 0.1)
