LH stimulates an increase in prostaglandins in vitro in preovulatory follicles from rats pretreated with PMS gonadotropin. The role of cAMP in this action of LH was examined by incubating preovulatory follicles with various substances and d…

The possibility that prostaglandins might be responsible for the development of the pre-ovulatory refractoriness to the stimulation by LH of cyclic AMP accumulation in vitro in the Graafian follicle was examined. Isolated rabbit Graafian fo…
