From: Protective effect of antioxidants on the pre-maturation aging of mouse oocytes

Effects of antioxidants on oocyte maturation after pre-maturation aging and IVM. Oocytes at GV stage were directly cultured (Fresh) or pre-maturation aging for 12 (a) 24 (b) and 36 h (c) in a medium supplemented with (AO) or without (control) antioxidants before IVM. *P < 0.05; **P < 0.01; ***P < 0.001. No. of oocytes at each group was shown in the bracket. AO: antioxidants.
