Testicular delta 5-3 beta-hydroxysteroid dehydrogenase in toad (Bufo melanostictus) following prolonged exposure to heat
Acta Histochem.
1975.
Abstract
In contrast to our previous observation of increased activity of testicular delta5-3beta-hydroxysteroid dehydrogenase in toad with relation to the moderate rise of external temperature (40 degrees C), the present observation, however, shows a significant fall of this enzyme in the testis of toads exposed to a considerably high temperature (48 degrees C). The possible mechanism of action of heat on testicular steroid hormone synthesis has been discussed.
