This invention discloses methods of administering 4-hydroxytestosterone in order to lower estrogen levels in humans. As men age, a decline in androgenic hormone levels is typically noted, possibly resulting in muscle mass, bone density and energy loss. This is often accompanied by elevated estrogen to androgen ratio. Various methods have therefore been developed to supplement androgens for men with declining levels and/or correct this ratio. Some such have focused on the use of direct aromatse inhibitors, as a means of lowering levels of estrogen in humans. This invention is an improvement over the use of the aromatase inhibitor 4-hydroxyandrostenedione, in that the subject of this invention is an aromatase inhibitor developed by modifying an active androgen instead of an inactive metabolite. This may be a very advantageous trait for aging men who require a safe and effective way to treat estrogen/androgen imbalance. |
