The present invention concerns the novel compounds having fluoro, amino, nitro or hydroxy monosubstituted at the 2- or 4- position on deoxyestrone as well as deoxyestra-17-ol. The compounds are useful as estrogen sulfotransferase inhibitors. Such estrogen sulfotransferase inhibition provides the novel use for treating a female mammal to prevent implantation of a blastocyst. Additionally, the invention concerns the novel synthesis and novel intermediates in the synthesis of the estrogen sulfotransferase inhibiting compound of the present invention.
