transmission to female partners – it takes months to clear the drug from
the system

 Gel: applied daily to one arm from shoulder to wrist
 Patches: apply to trunk region (not breast or waistline)
o Highly advantageous due to:

 decreased fluctuation of estrogen blood levels
 lower risk for DVT
 total estrogen dose greatly reduced (bypasses
liver)
o Intravaginal
 Inserts, creams, and rings
 Only used for local effects
