Reactions
NAD+ + Androstan-3alpha,17beta-diol = NADH + H+ + Dihydrotestosterone
NAD+ + Cortolone = NADH + H+ + Tetrahydrocortisone
NAD+ + Cortol = NADH + H+ + Urocortisol
NAD+ + 3alpha,20alpha,21-Trihydroxy-5beta-pregnane-11-one = NADH + H+ + 3alpha,21-Dihydroxy-5beta-pregnane-11,20-dione
NAD+ + Pregnanediol = NADH + H+ + 3alpha-Hydroxy-5beta-pregnane-20-one
