<unk>  <unk> -DHD), also known as<unk> -hydroxydydrogesterone, as well as 20(S)-hydroxy-9β,10α-pregna-4,6-dien-3-one, is a progestin and the major active metabolite of dydrogesterone. It appears that dydrogesterone is a prodrug of<unk> -DHD, as it is largely transformed into this metabolite when given orally in humans.<unk> -DHD has progestogenic activity similarly to dydrogesterone, but is far less potent in comparison.
