The enzyme 11beta-hydroxysteroid dehydrogenase (11beta-HSD) catalyzes the reversible conversion of physiologically active corticosterone to the biologically inert 11beta-dehydrocorticosterone in rat testis and protect the Leydig cells (LCs) against the suppressive effect of glucocorticoids. The developmental pathway of the adult LCs population is accompanied with an increase in the 11beta-HDS a...
