This work proposes in a critic way different conceptions regarding gender, and states that it is a powerful cultural construction that organizes social life. Initially, three conceptions are introduced: origins of patriarchy, Marxist theories and feminism, and French psychoanalytic theory. To conclude, some contributions of the poststructuralist theory –in terms of displacement and political relocation- are established. Basically, the work aims at questioning the normative conceptions of gender.
