3β-HSD II mediates three parallel dehydrogenase/isomerase reactions in the adrenals that convert Δ 4 to Δ 5 steroids: pregnenolone to progesterone, 17α-hydroxypregnenolone to 17α-hydroxyprogesterone, and dehydroepiandrosterone (DHEA) to androstenedione. 3β-HSD II also mediates an alternate route of testosterone synthesis from androstenediol in the testes. 3β-HSD deficiency results in ...
