17α-羥孕酮（英語：17α-Hydroxyprogesterone，17α-OHP)，有時就簡稱為羥孕酮（英語：hydroxyprogesterone，OHP）是一種孕酮類似的內源性的孕激素類甾體激素^[1]^[2]^[3]，同時也是很多內源性甾體激素生物合成的前體，包括雄激素、雌激素、糖皮質激素和鹽皮質激素以及一些神經甾體。

生物學活性[編輯]

由於和孕酮的相似性，17α-OHP是孕酮受體（PR）的一種激動劑，但相比之下比較弱^[4]。另外，也是一種鹽皮質激素受體（MR）的拮抗劑^[5]，也是糖皮質激素受體（GR）的部分激動劑，其EC₅₀不到皮質醇的百分之一^[4]^[6]^[7]。
