Polymorphisms presents an overview of key theories, ideas and issues within psychoanalysis relating to sexual and gender diversity.

The chapters consider key topics including the Oedipus-castration complex, the link between sexuality and gender, identity, and gender violence, while also addressing queer/transgender subjectivities, countertransference, and the implicit and explicit theories that shape clinical practice. Taking an intra and interdisciplinary approach, the collection considers ideas that enrich the clinical approach while highlighting contradictions and heterogeneities, and moving away from essentialisms. As a whole, the book delimits debates and questions rather than offering definitive answers, taking the perspective that psychoanalysis is a discipline in continuous interrogation of its own propositions.

Polymorphisms: Sexual and Gender Migrations in Contemporary Psychoanalysis will be essential reading for psychoanalysts and psychotherapists in practice and in training. It will also be of interest to academics of psychoanalytic studies and gender studies.
