Disclosed are progestin agonists having the following formula: STR1 W is absent or --CH=CH--; R1 are independently selected from the group consisting of halogen, --CF3, and NO2, or both R1 may be joined to form a bi-radical which is --CH=CHCH=CH--; R3 are independently selected from the group consisting of hydrogen, C1-6 branched or linear alkyl, halogen and --CF3, with the proviso that R3 at the 3-position must be H where R3 at the 4-position is H, or both R3 may be joined to form a bi-radical selected from the group consisting of --CH=CHCH=CH--, --C(NC1-4 alkyl2)=CHCH=CH-- and --(CH2)4 --; R5 is selected from the group consisting of H and Me; with the proviso that only one of R1 and R3 forms the fused bi-radical; and the stereoisomers.
