This paper aims to punctuate a first exploration on the development of the output of the subject of hysterical discourse, in Lacan´s teach; the one that will give him the basis for the writing of the formulas of sexuation. In deed, Lacan,  at the end of his discourses theory, in his eighteen seminar, in the early seventies, initiate the inquiry that will leed him, a few years later, to establish his famous formulas. Set out the broad lines of his teaching, especially by Jaques-Alain Miller in his courses of The Lacanian Orientation, it is of great interest to review in it those details and reflections that accompany the passages from one period to another, also with the clinical references in which it rests.
