Title:	Estrogenic compounds and pharmaceutical formulations comprising the same
Abstract:	Novel estrogenic compounds of Formula I are provided. ##STR00001## wherein the bond represented by the wavy line may be a single or double bond such that when the wavy line is a single bond, R.sub.1 is selected from the group consisting of hydrogen, sulfate and glucoronate or other esters, and when the wavy line is a double bond, R.sub.1 does not exist; R.sub.2 is lower alkyl; R.sub.3 may be selected from the group consisting of hydrogen, sulfate, or glucuronide or other esters; and R.sub.4 through R.sub.13 may independently be selected from the group consisting of hydrogen, hydroxy, ketone, lower alkyl, lower alkoxy, halogen, and carbonyl groups and R.sub.14 is selected from the group consisting of hydrogen, sulfate and glucoronide and other esters. When R.sub.1 is hydroxy, the hydroxy or ester substituent may have either an .alpha. or a .beta. orientation. Compositions of matter including compounds of the present invention are also provided as are methods of treating mammals in need of treatment using compounds of the present invention.
