Abstract: The stimulatory effect of a new analogue of chicken I. gonadotropin-releasing hormone (Folligen) has been studied on specimens of marsh frog, Rana ridibunda. Folligen increased plasma testosterone (T) levels and induced breeding behaviour both during and out of the spawning season. Folligen (GnRHa) significantly enhanced plasma T levels in frogs tested in summer, and estradiol remanied steady at high levels after the Folligen treatment. At the same time this hormone induced sexual activity of frogs in the postreproductive phase, too. According to our current and previous results, Folligen is suitable for stimulation of reproductive functions in lower classes of vertebrates.
