title: Endocrine profile of topterone, a topical antiandrogen, in three species of laboratory animals.
abstract: Topterone, 17 alpha-propyltestosterone, was administered parenterally or topically to rats, rabbits or hamsters to determine its endocrine profile. Systemic administration demonstrated that topterone was both antiandrogenic and progestational. Topical application failed to elicit a systemic antiandrogenic response at 1 g/kg/day and only a minimal progestational response was seen at 32 mg/kg/day. No other endocrine activities were detected.
