## Abstract To further investigate the action of gonadotropinβreleasing hormone (GnRH) on gonadotropin (Gth) secretion and synthesis, pituitaries from frogs, __Rana pipiens__, were incubated in the presence or absence of 100 ng/ml GnRH for 12 h. GnRH was then removed from the medium and glands were
Individual ovarian follicles of Rana pipiens respond to hormonal stimuli in vitro. The relative effectiveness of progesterone and gonadotrophic hormones in initiating ovulation and oocyte maturation were compared. Maturation of oocytes ( > 99%) with limited concomitant ovulation resulted following t
