Prostaglandins and the rat seminal vesicle: effects of mating and adrenergic stimulation
Abstract:
The concentrations of PGE, PGF, and 6-keto-PGF1 alpha were increased in rat seminal vesicle tissue following mating activity. Likewise, synthesis of PGE and PGF was stimulated by epinephrine (3 X 10(-7) to 3 X 10(-6) M) in tissues and media from in vitro incubations of intact rat seminal vesicles. The in vitro stimulation was inhibited by phentolamine, an alpha-adrenoreceptor blocking agent. Carbamylcholine (2 X 10(-6) M) and bradykinin (1 X 10(-6) M) had no effect on PGE or PGF synthesis, even though both compounds stimulated contractility of the rat seminal vesicle at these concentrations. These data suggest that mating and adrenergic stimulation increase prostaglandin synthesis in the rat seminal vesicle, probably through an alpha-adrenergically mediated mechanism.
