Effects of heat stress on E2 and P4 secretion by bovine granulosa cells: Concentration of E2 (a) and P4 (b) in culture media of bovine granulosa cells (bGCs) cultured under heat stress (39, 40 and 41 °C) and corresponding control (38 °C). Values are expressed as mean ± SEM of n = 3. Superscripts (a, b, c) show significant difference, P < 0.05
