Lapachol, a naphthoquinone extracted from plants of the genus Tabebuia (family Bignoneaceae), showed multiple therapeutic activities. Pregnant Wistar rats were treated with Lapachol from the 1st to the 4th (pre-implantation period) and from 5th to 7th (implantation period) post insemination day (PID). Mothers were sacrificed on the 5th or on the15th PID. Number of corpora lutea, preimplantation embryo, blastocysts, live and dead fetuses and resorptions were counted. There were no signs of maternal toxicity. The number and the morphology of embryos, during oviduct development (pre-implantation period), did not seem to be affected by this drug, but during the implantation period, lapachol was toxic causing the death of embryos and intrauterine growth retardation.
