The adenyl cyclases of chick oviduct and rat prostate were not stimulated by estrogen and testosterone, respectively, suggesting that growth and differentiation of these target tissues are not mediated by adenosine 3',5'-monophosphate. Estrogen acutely activated adenyl cyclase in the castrate rat uterus, but this was prevented by administration of DL-propranolol, suggesting that the effect was mediated by catecholamines. Progesterone produced a delayed stimulation of oviduct adenyl cyclase preceding and concomitant with the induction of synthesis of avidin.
