In order to investigate the effects of antioxidants on the culture of mouse preantral follicles in vitro, we examined the effects of taurine, glutathione and catalase on their growth and maturation. Addition of taurine was not effective on the survival of preantral follicles. However, metaphase II rates of oocytes within preantral follicles were significantly higher in 1 mM treated group than in control and 10 mM treated group (p<0.05). Glutathione did not improved the rates of survival and metaphase II oocytes. However, metaphase II rates of oocytes progressively decreased with increasing glutathione concentration. Catalase also showed that the rates of survival and metaphase II oocytes progressively decreased with increasing concentration. Especially, all of preantral follicles cultured in medium containing 100 IU/ml catalase were degenerated. These results suggest that low concentraion of taurine, as an antioxidant, have positive effect on the culture of mouse preantral follicles in vitro.
