摘要: Di (2-ethylhexyl) phthalate (DEHP) is male developmental toxicant that impairs testis development with reduced anogenital distance. The present study aimed to investigate whether maternal DEHP exposure during pregnancy causes intrauterine growth restriction (IUGR) in a gender-specific manner and identify the critical window of DEHP-induced fetal IUGR. Pregnant mice were administered (0, 50 or 200mg/kg) by gavage. Fetal IUGR was observed not only males but also females when litters exposed on gestational day (GD)0-GD17. Interestingly, weight crown-rump length reduced, markedly dams GD13-GD17, slightly GD7-GD12, GD0-GD6. Further analysis showed GD7-GD12 inhibited cell proliferation, lowered placental weight, blood sinusoid area labyrinth layer. These results suggest induces stage-specific gender-independent manner.
