The asymmetric unit of the title compound, C19H28O3, contains two independent molecules with almost identical geometry. The molecules have a planar 5 alpha configuration as a result of a trans-A/B junction of the rings. The compound crystallizes in a triclinic cell, which is unusual for steroids. The molecules are linked head-to-tail via hydrogen bonds between the ring A hydroxyl group and the ketone group of ring D, forming two independent chains running along the c axis.
