Pregnane, also known as 17β-ethylandrostane or as 10β,13β-dimethyl-17β-ethylgonane, is a C21 steroid and, indirectly, a parent of progesterone. It is a parent hydrocarbon for two series of steroids stemming from 5α-pregnane (originally allopregnane) and 5β-pregnane (17β-ethyletiocholane). It has a gonane core.

孕烷（Pregnane）也稱為孕甾烷，是有21個碳原子的甾體，有腺甾烷的基本結構，是孕酮的，也是一些腎上腺皮質激素（例如可的松）的母體。孕烷包括5α-孕烷（别孕烷，allopregnane）和5β-孕烷（17β-乙基本胆烷）两系列类固醇的母体碳氫化合物。 5β-孕烷是孕酮、孕二醇、孕烷醇酮等甾类的母体，5β-孕烷存在尿液中，是5β-孕烷化合物的代谢产物。
