Gestronol (BANTooltip British Approved Name), also known as gestonorone, as well as 17α-hydroxy-19-norprogesterone or 17α-hydroxy-19-norpregn-4-ene-3,20-dione, is a progestin of the 19-norprogesterone and 17α-hydroxyprogesterone groups which was never marketed.[1][2][3] The C17α caproate ester of gestronol, gestonorone caproate (gestronol hexanoate), in contrast, has been marketed.[1][2][3]

Gestronol shows relatively low affinity for the progesterone receptor, only about 12.5% of that of progesterone and about 2.5% of that of 19-norprogesterone in one assay.[4] On the other hand, gestronol had far higher affinity than 17α-hydroxyprogesterone, which showed less than 0.1% of the affinity of progesterone for the progesterone receptor.[4]
