PG - 269-73 LID - 10.1111/j.1741-4520.2009.00247.x [doi] AB - Estrogens cause embryonic lethality and the disturbance of early placental development in mice. Diethylstilbestrol (DES) at 1, 10, or 100 microg/kg was orally administered to Institute of Cancer Research mice on gestational days (GD) 4 through 8, and the uterus and placenta were examined histopathologically on GD 9. Decidua of DES-treated mice showed insufficient development, and the uterine lumen at the implantation site did not effectively minimize. The trophoblast giant cell layer was not separated from the uterine lumen by the decidua capsularis, and hemorrhage from the denuded trophoblast giant cell layer into the uterine lumen was noted at the peripheral part of the decidua basalis. The results of the present study suggest that decidual hypoplasia and subsequent placental hemorrhage causes fetal death due to the administration of DES during the early stage of pregnancy.
