Teratogenic Effects

May cause birth defects (teratogenic effects) based on animal test data Showed teratogenic effects in animal experiments High doses of methylene chloride given to pregnant rats and mice were shown by one study to increase the incidene ofminor skeletal anomalies although other studies in rats found this agent not to be associated with an increase in congenital anomalies
