 Preciado investigates the politicization of the body by what he terms "pharmacopornographic capitalism".Preciado described the act of taking testosterone as both political and performance, aiming to undo a notion of gender encoded in one's own body by a system of sexuality and contraception.In the work, Preciado describes and analyses the changes provoked by the testosterone from the point of view of the relationship with Virginie Despentes (referred to as "VD" in the book).
