Objective To investigate the effect of exposure to bisphenol A (BPA) on maturation and oxidative stress injury in mouse oocytes in vitro. Methods Oocytes from female ICR mice were randomly divided into control group, DMSO group,and BPA group. Mouse oocytes in control group was cultured normorly in vitro,while added 0.1% DMSO in DMSO group, and 45 μmol/L BPA in 0.1% DMSO in BPA group. MII oocytes and oocytes stagnated in the GV phase were obtained .The levels of ROS in MII and GV oocytes of each group was detected by kit. The expression level of antioxidant enzyme in MII and GV oocytes was detected by immunofluorescence and Western blotting. Results Compared with control group, exposure to 45 μmol/L BPA during in vitro maturation, resulted in a significant decrease in the maturation rate of mouse oocytes in BPA group (26.32%±1.12%vs. 98.22%±0.89%, P<0.05), the levels of ROS in GV and MII oocytes were significantly higher (P<0.05), the levels of antioxidant enzymes CAT and SOD2 in GV and MII oocytes were significantly decreased (P<0.05). Conclusion Exposure to 45 μmol/L BPA increased ROS production and inhibited antioxidant enzyme expression, leading to oxidative stress damage of mouse oocytes and thus inhibiting oocyte maturation in vitro.
