Reactions
NAD+ + 20alpha-Hydroxy-4-pregnen-3-one = NADH + H+ + Progesterone
NADP+ + 20alpha-Hydroxy-4-pregnen-3-one = NADPH + H+ + Progesterone
NADP+ + 17alpha,20alpha-Dihydroxypregn-4-en-3-one = NADPH + H+ + 17alpha-Hydroxyprogesterone
NADP+ + 5alpha-Pregnan-20alpha-ol-3-one = NADPH + H+ + 5alpha-Pregnane-3,20-dione
NADP+ + 5alpha-Pregnane-3alpha,20alpha-diol = NADPH + H+ + 3alpha-Hydroxy-5alpha-pregnan-20-one
