Bisphenol-A exposure during the period of blastocyst implantation alters uterine morphology and perturbs measures of estrogen and progesterone receptor expression in mice

Bisphenol-A (BPA) has estrogenic properties both in vitro and in vivo. We investigated its impacts upon uterine morphology and estrogen and progesterone receptors after injection on gestational days 1-4 in doses known to disrupt pregnancy. Blastocyst implantation was significantly reduced by doses of 6.75 and 10.125 mg/animal. Uterine luminal area expanded substantially in response to increasing doses of BPA. Luminal epithelial cell height …
