6α-fluorotestosterone (6α-fluoro T) acts as a competitive inhibitor of aromatase cytochrome P450. The mechanism by which substitution of a fluorine at the 6 alpha-position interferes with the aromatization reaction remains to be determined, but the inhibitory action on estrogen formation may potentiate the androgenic properties of 6 alpha-fluorotestosterone in vivo due to a lowering of estrogen levels. Besides, 6α-fluoroT promotes male sex behavior, it does not promote mating by unassisted estrogen receptor binding and it does not promote mating via metabolism to another androgen.

Sample Use Guides
how mating induced in castrated male rats by 6α-fluorotestosterone: starting the day after castration, one set was injected sc daily with 6α-fluorotestosterone (6α-fluoroTP) at a dose of 25 μg/day. That was increased to 50 μg after week 5, 100 μg after week 6, 200 μg 4 days after week 7, and 400 μg after week 8.

In Vitro Use Guide
Curator's Comment: Under conditions in which testosterone was readily aromatized, no aromatization of 6 alpha-fluorotestosterone was observed using either fluorescence detection of dansyl-estrogens separated by high-performance liquid chromatography or estrogen radioimmunoassay methods. The lack of aromatization is not due to failure of 6 alpha-fluorotestosterone to bind to P450arom because 6 alpha-fluorotestosterone acts as a competitive inhibitor of the enzyme, and it exhibits a binding affinity similar to that of testosterone. Moreover, the addition of 6 alpha-fluorotestosterone to human placental microsomes elicits a spectral shift indicative of conversion of the heme from a low to a high spin state as observed for androgen substrates, consistent with its binding to the substrate site.
