    The title compound, C19H26O4, was biotransformed from androstenedione. In the crystal, inter­molecular O—H⋯O hydrogen bonds link molecules into a corrugated sheet, which lies parallel to the ab plane. Ring A has a slightly distorted half-chair conformation, rings B and C adopt chair conformations, while the cyclo­pentane ring D adopts a 14α-envelope conformation
