We had previously reported that 6-methylene progesterone, an inhibitor of 5 alpha-reductase, the enzyme which converts testosterone to dihydrotestosterone, markedly inhibited growth of the androgen-dependent Dunning R3327-H rat prostatic tumors. We now find that the progesterone derivatives melengestrol acetate (MGA)
