Carbohydrate metabolism of COCs during IVM over time. Effect of oocyte presence (COC; yellow) vs. granulosa cells only (blue) on glucose consumption (A), lactate production (B), lactate: glucose ratio (C) and pyruvate production (D) over the time course of IVM. Mean ± SEM are depicted and asterisks represent significant difference between conditions at that time point (n = 56; p < 0.05). Different superscripts indicate differences between time points in the COC data (yellow line).
