Patent Claims:	1. A method of inhibiting bone loss comprising administering to a human in need of treatment an amount of a compound of Formula I ##STR11## wherein X is a bond, CH.sub.2, or CH.sub.2 CH.sub.2 ; R and R.sup.1, independently, are hydrogen, hydroxyl, C.sub.1 -C.sub.6 -alkoxy, C.sub.1 -C.sub.6 -acyloxy, C.sub.1 -C.sub.6 -alkoxy-C.sub.2 -C.sub.6 -acyloxy, R.sup.3 -substituted aryloxy, R.sup.3 -substituted aroyloxy, R.sup.4 -substituted carbonyloxy, chloro, or bromo; R.sup.2 is a heterocyclic ring selected from the group consisting of pyrrolidino, piperidino, or hexamethyleneimino; R.sup.3 is C.sub.1 -C.sub.3 -alkyl, C.sub.1 -C.sub.3 -alkoxy, hydrogen, or halo; and R.sup.4 is C.sub.1 -C.sub.6 -alkoxy or aryloxy; or a pharmaceutically acceptable salt thereof, that is effective to inhibit bone loss in a human. 2. A method of claim 1 wherein the human has been diagnosed as suffering from osteoporosis. 3. A method of claim 1 wherein the human is a post-menopausal female. 4. A method of claim 1 wherein the human is a male. 5. A method of claim 1 wherein the compound is administered prophylactically. 6. A method of claim 1 wherein X is a bond. 7. A method of claim 1 wherein R.sup.2 is piperidino or pyrrolidino. 8. A method of claim 6 wherein R.sup.2 is piperidino or pyrrolidino. 9. A method of claim 6 wherein R.sup.2 is piperidino. 10. A method of claim 6 wherein R.sup.2 is pyrrolidino. 11. A method of claim 1 wherein R and R.sup.1 are both hydroxyl, C.sub.1 -C.sub.6 -acyloxy, C.sub.1 -C.sub.6 -alkoxy-C.sub.2 -C.sub.6 -acyloxy, R.sup.3 -substituted aroyloxy, or R.sup.4 -substituted carbonyloxy. 12. A method of claim 11 wherein R and R.sup.1 are both hydroxyl. 13. A method of claim 11 wherein R and R.sup.1 are both C.sub.1 -C.sub.6 -acyloxy. 14. A method of claim 13 wherein R and R.sup.1 are both n-butanoyloxy, 2,2-dimethylpropanoyloxy, or 3 3-dimethylbutanoyloxy. 15. A method of claim 11 wherein R and R.sup.1 are both R.sup.4 -substituted carbonyloxy. 16. A method of claim 15 wherein R and R.sup.1 are both methoxycarbonyloxy or phenyloxycarbonyloxy. 17. A method of claim 11 wherein R and R.sup.1 are both R.sup.3 -substituted aroyloxy. 18. A method of claim 17 wherein R and R.sup.1 are both benzoyloxy, methylbenzoyloxy, or naphthoyloxy. 19. A method of claim 8 wherein R and R.sup.1 are both hydroxyl, C.sub.1 -C.sub.6 -acyloxy, C.sub.1 -C.sub.6 -alkoxy-C.sub.2 -C.sub.6 -acyloxy, R.sup.3 -substituted aroyloxy, or R.sup.4 -substituted carbonyloxy. 20. A method of claim 9 wherein R and R.sup.1 are both hydroxyl. 21. A method of claim 10 wherein R and R.sup.1 are both hydroxyl. 22. A method of claim 8 wherein R and R.sup.1 are both C.sub.1 -C.sub.6 -acyloxyl. 23. A method of claim 22 wherein R and R.sup.1 are both n-butanoyloxy, 2,2-dimethylpropanoyloxy, or 3 3-dimethylbutanoyloxy. 24. A method of claim 8 wherein R and R.sup.1 are both R.sup.4 -substituted carbonyloxy. 25. A method of claim 24 wherein R and R.sup.1 are both methoxycarbonyloxy or phenyloxycarbonyloxy. 26. A method of claim 8 wherein R and R.sup.1 are both R.sup.3 -substituted aroyloxy. 27. A method of claim 26 wherein R and R.sup.1 are both benzoyloxy, methylbenzoyloxy, or naphthoyloxy. 28. A method of claim 1 wherein the compound of formula I is administered in an amount of 0.1 to 1000 mg. 29. A method of claim 1 wherein the compound of formula I is administered in an amount of 200 to 600 mg. 30. A method of claim 1 wherein the compound of formula I is administered in an amount of 600 to 1000 mg. 31. A method of claim 20 wherein the human has been diagnosed as suffering from osteoporosis. 32. A method of claim 20 wherein the human is a post-menopausal woman. 33. A method of claim 20 wherein the compound is administered prophylactically. 34. A method of claim 1 wherein the administration of a compound of formula I does not significantly affect the primary sex target tissues. 35. A method of claim 1 wherein a compound of formula I is administered in combination with estrogen.
