This paper discusses the uses of testosterone among transsexual men and its relation to healthcare. It addresses how the use of testosterone-based drugs crisscross, interact and reiterate the processes of construction of the subjects designated as transsexual men. It analyses trans men's experiences and narratives, as well as their view of healthcare, both in trans-specific healthcare clinics and in everyday experiences in other social realms. The discussion is based on interviews with six transsexual men in the city of Rio de Janeiro.
