Introduction: Intersexuality includes extremely rare conditions where a person is born with a sexual anatomy different from the male-female binary; this supposes inhabiting a body outside the intelligible, configuring a stigma. Historically and from the heteronorm, the biomedical model has sought to surgically normalize them in order to precociously and arbitrarily assign a gender in harmony with genitality. From Human Rights, these practices have been questioned by Intersex groups. Materials and method: During the years 2019 and 2020, case studies were carried out through in-depth interviews with two adult users of the Urology and Endocrinology Polyclinics of a public hospital at Santiago, Chile; Husserl's phenomenology was used to visualize the phenomenon according to how it is experienced by the subjects who carry it, using the procedure described by Colaizzi as an information analysis plan. Results: Main and overlapping units of meaning were recognized, whose essences allowed describing the phenomenon of: being a child and inhabiting the hospital space, currently living with the condition, and the experience of using the health system as an adult, with new and own meanings. Conclusions: Various agency strategies were identified both in the hospital space and in everyday life, through a personal and silent process of learning about the implications of being intersex.
