Bisphenol a Interferes with Uterine Artery Features and Impairs Rat Feto-Placental Growth.

ABSTRACT: Bisphenol A (BPA) is a widespread environmental contaminant, found in human fluids and tissues. Maternal BPA exposure is associated with alterations in pregnancy outcomes. Because maternal uterine circulation plays a crucial role in normal placenta and fetal growth, we hypothesized that BPA compromises the function of uterine arteries (UAs) and fetoplacental development. Female rats were orally administered with BPA (2.5, 25 and 250 µg/kg/day) or with its vehicle (ethanol) for 30 days before pregnancy and during the first 20 days of pregnancy. To compare the effect of BPA in the reproductive vs. systemic circulation, it was tested on UAs and mesenteric arteries (MAs). Arteries were isolated and examined by pressure myography. Moreover, fetuses and placentas were weighed to provide an index
