In the title compound, alternatively called 3′-oxocyclohex-1′-eno-1′,6′:16,17-3-O-methylestra-1,3, 5(10),16(16H)-tetraen-3-ol, C23H28O2, the cyclohexenone ring is fused to the five-membered ring through the a position at C16. As a result of the ring annelation, the distance between carbonyl and methoxy O atoms [12.994 (2) Å] is much longer than that in estrones or estradiol. The crystal packing is stabilized by C-H⋯O and C-H⋯π hydrogen-bonding interactions.
