Seasonal variation of androgen interconversion in testicular tissue of Rana temporaria in vitro.
Testicular steroid metabolism of winter and spring frogs, Rana temporaria, were studied by in vitro incubation with radioactively labelled dehydroepiandrosterone and androst-4-ene-3,17-dione. Marked seasonal differences were observed which are in line with the findings of others.
