This article is a review of the international scientific literature on informed consent and its use in some of the constituent organizations of the International Psychoanalytical Association (IPA). Because psychoanalysis comprises a theory based on practice, the dearth of clinical material for study, training and research purposes is a serious problem for analysts. Supervisions, presentations at scientific societies and congresses, publications and teaching material involve patients to an extent that goes beyond the work done in their sessions. Should consent be requested in these cases? This contribution addresses controversial and long-standing issues such as informed consent and confidentiality, audio recording of treatments, knowledge production, the ambivalence of participating subjects over time and the perspective of analysts and patients respectively. The authors consider the various alternative approaches available for the handling of these ethical dilemmas without losing sight of the patient's dignity and personal rights, while also taking account of the position of the analyst.
