4-Vinylcyclohexene (VCH), a dimer of 1,3-butadiene, was evaluated for reproductive toxicity in Swiss (CD-1) mice using the continuous breeding protocol (NTP, 1989). VCH in corn oil was administered by gavage at doses of 0, 100, 250, and 500 mg/kg/day to animals that were housed in same sex pairs for 1 week and then cohabited in breeding pairs for 14 weeks. During cohabitation, newborn litters were euthanized immediately after evaluation on postnatal Day (PND) 0. Litters born after Week 15 were reared until PND 21, when all F0 animals and low- and mid-dose F1 weanlings were humanely killed without a necropsy. At PND 74 +/- 10, control and high-dose F1 animals were cohabited within groups for 1 week and necropsied after delivery of the litters. In F0 breeding pairs, VCH did not affect measures of reproductive competence, including initial fertility, litters per pair, live litter size, or the proportion of pups born alive. Pup weight was decreased (4%) in the high-dose group relative to controls. High-dose F0 females exhibited slight general toxicity, manifested as an 8% difference in body weight compared to controls. VCH did not adversely affect preweaning growth or survival in the F1 generation. VCH had no effect on the reproductive competence of the F1 generation. High-dose F1 adult males and females had decreased body weight. At necropsy, increased relative liver weight (males 9% and females 8%) and sperm motility (although not thought to be biologically significant) were observed in the 500 mg/kg VCH group.(ABSTRACT TRUNCATED AT 250 WORDS)
