Plasma and testicular estradiol and plasma androgen profile in the male frog Rana esculenta during the annual cycle.
Bruno Varriale,Riccardo Pierantoni,L. Di Matteo,Sergio Minucci,Silvia Fasano,Mauro D'Antonio,Giovanni Chieffi +6 more
TL;DR: Seasonal plasma and testicular estradiol levels were measured in the male frogs, Rana esculenta, by radioimmunoassay and a simultaneous measurement of androgens was carried out in order to investigate a possible relationship between androgens and Estradiol-17 beta.

Regulation of androgen production by frog (Rana esculenta) testis: An in vitro study on the effects exerted by estradiol, 5α-dihydrotestosterone, testosterone, melatonin, and serotonin☆
Riccardo Pierantoni,Bruno Varriale,Sergio Minucci,L. Di Matteo,Silvia Fasano,Mauro D'Antonio,Giovanni Chieffi +6 more
TL;DR: The data suggest that steroids may regulate their intratesticular levels without passing into the blood stream.

Nature and distribution of gonadotropin-releasing hormone (GnRH) in the brain, and GnRH and GnRH binding activity in serum of the spotted dogfish Scyliorhinus canicula.
Mauro D'Antonio,Mauro Vallarino,David A. Lovejoy,Francois Vandesande,Judy A. King,Ricardo Pierantoni,Richard E. Peter +6 more
TL;DR: The presence of a GnRH-BP in spotted dogfish serum suggests a probable action of GnRH via the general circulation, and the characteristics of four of these GnRH peptides are consistent with those of m-, cII-, dogfish (df-), and sGnRH; the fifth form appears to be novel.

TL;DR: The results indicated that an opioid system modulates the hypothalamus-pituitary-gonadal axis in the frog, Rana esculenta and, for the first time, it is shown that the testicular activity of a non-mammalian species may be regulated by opiates locally.

Sites of action of local estradiol feedback mechanism in the frog (Rana esculenta) testis.
TL;DR: It is concluded that estradiol acts by decreasing the activity of steroidogenic enzymes starting from 17,20-lyase, while pituitary homogenate does not affect the 17 alpha-hydroxylase activity, but it acts starting from17,20,lyase.
