17alpha-methyl testosterone is a synthetic androgen with affinity for the androgen receptor. 17alpha-methyl testosterone is used widely as a component of hormone replacement therapy. previous reports have indicated that contrary to testosterone, 17alpha-methyl testosterone is not aromatized. however, 17alpha-methyl testosterone still could affect local estrogen formation by regulating aromatase expression or by inhibiting aromatase action. both possibilities have important clinical implications.
