Abstract
Abstract A method of treating androgen-related disorders in an animal which comprises administering to the animal dihydrotestosterone level decreasing amounts of a compound of formula (I): ##STR1## wherein R is H or F; R 1 is selected from the group consisting of --H; straight or branched chain lower alkyl; hydroxyl; --OCOR 3 ; and O--(C 1 -C 6 alkyl); wherein R 3 is --H, C 1 -C 10 straight or branched chain alkyl group, phenyl, phenyl alkylene having straight or branched chain C 1 -C 6 alkylene, C 5 -C 10 cycloalkyl or C 6 -C 10 cycloalkyl alkylene; R 2 is H 2 , methylene, ethylidene, α-CH 3 (H), β-CH 3 (H), α-(OH)(H) or the acetonide derived from the 16α,17α-dihydroxy derivative, and n is 1 or 2.
