Effects of TBTO exposure on intracellular ROS generation in porcine oocytes. (A) Representative fluorescence images showing intracellular ROS levels in porcine oocytes in the control and TBTO exposure group at the end of the IVM period. Scale bar = 200 μm. (B) Quantification of relative intracellular ROS levels in porcine oocytes from the control and TBTO exposure group. The numbers of oocytes examined from the different groups are indicated by the bars. ∗∗p < 0.01 compared to the control.
