Abstract

Ipriflavone has inhibitory effect on the cytochrome p450 and the proliferation of DNA, interfering with hormone
synthesis estereoidianos, and consequent interference with the transport and preimplantation development and
implantation of the blastocyst. Consumed in high doses can cause miscarriages and malformations. To verify the
embryotoxicity of ipriflavone during the phases of tubal transport and implantation of the blastocyst in rats, Wistar
rats were treated twice daily with 1 mL of aqueous suspension of ipriflavone at doses of 0 (C), 300 (T1), 1500 (T2)
and 3000 (T3) mg / kg / dose during the first eight days of pregnancy with euthanasia on day 14. Signs of toxicity
were characterized by hematological, biochemical and behavioral. Live fetuses were counted, dead and resorbed
(early and late). The animals showed no clinical signs of toxicity. Index pre-implantation embryo and losses suffered
interference from the use of ipriflavone. Data point to an estrogenic effect of ipriflavone, due to interference in
blastocyst implantation in Wistar rats.
