title: Collaborative work on evaluation of ovarian toxicity. 4) Effects of fertility study of 4-vinylcyclohexene diepoxide in female rats.
abstract: As part of a collaborative project, 4-vinylcyclohexene diepoxide (VCD), an ovarian toxicant, was intraperitoneally administered to female Sprague-Dawley rats at 0, 5, 20 or 80 mg/kg from 2 weeks prior to mating to Day 7 of gestation. At necropsy, the number of implanted embryos, rate of implantation decreased and the rate of preimplantation loss showed an increasing tendency in the 80 mg/kg group. As for organ weight, decreases in absolute and relative ovary weight were observed in the 80 mg/kg group. Histopathologically, the ovaries showed a decrease in number of small follicles at 80 mg/kg
