Abstract. The potential teratogenicity of the antioxidant stobadine (STO) was studied in Wistar rats. Daily oral doses of 5, 15 and 50 mg/kg STO were given from the 6th day of gestation up to weaning of pups -day 21 post partum. No significant differences between the STO treated groups and the control group were found in litter size, pre-and postimplantation losses and foetal body weight. Ex ternal, skeletal and internal examinations of the foetuses revealed no evidence of teratogenesis. The offspring from the STO treated dams exhibited a high survival rate in their postnatal development. It can be concluded that STO had no adverse effects on the pre-and postnatal development of the offspring in rats
