**1. Introduction**

Autoethnography has been used as a qualitative research method through which the researcher describes his or her own experience for a sociological understanding of the phenomena studied. In recent years autoethnography has begun to be considered not only as a research method, but also as a "genre of writing, research, history and method that connects the autobiographical and personal with the cultural, social and political" ([1], p. xix), as Carolyn Ellis points out. This text focuses on the description of the use of autoethnography in my experience as an intern, social manager and researcher at the CERESO of San Miguel. The purpose is to present the autoethnographic work and the data collection techniques used in the doctoral research that have served to validate the evocative narrative [2] as a methodological tool in the construction of a new feminist knowledge confinement in prision and also to explore the connection between the individual and the collective.
