Effects of in utero exposure to arsenic during the second half of gestation on reproductive end points and metabolic parameters in female CD-1 mice

Mice exposed to high levels of arsenic in utero are more susceptible to tumors such as hepatic and pulmonary carcinoma when they reach adulthood. However, effects of in utero arsenic exposure on general physiological functions such as reproduction and metabolism remain unclear. The researchers evaluated the effect of in utero exposure to inorganic arsenic at the EPA drinking water standard (10 ppb) and tumor-inducing level (42.5 ppm) on reproductive end points and metabolic parameters when the exposed females reach adulthood.
