Fig. 3. Mean progesterone (Ln ± S.E.M.) production by 10,000 granulosa cells from the F1 follicle of laying hens, after 0–24 (j) or 24–48 h (h) of in vitro culture. Effect of time
of culture (A), and their interaction with LH (B) or Testosterone (C) treatments are shown. Progesterone production differ (P < 0.01) between time periods. Adapted from:
