Experimental design: Pregnant CD-1 females were exposed to 0 (control), 10 ppb, or 42.5 ppm sodium arsenite in drinking water from E10 to birth. At birth, pups were fostered to females that had not been not exposed to arsenic. Vaginal opening was checked daily starting at 18 days of age, and body weight was recorded weekly for 15 weeks. At 8 weeks of age, female pups were included in the fertility study or analyzed for metabolic end points. The sample size for each experiment is listed in Table 1.
