Providing new approaches for exploring gender identity and expression, this book is ideal for clinical practice with transgender and gender nonconforming/diverse clients. Importantly, it moves beyond the medical model to advance an understanding of transgender subjectivity as a natural variation of gender in humans.

The book deepens understanding of the developmental trajectory of trans and gender non-conforming individuals over their lifespan, before and beyond transition, by offering new theories on gender. Drawing on theories from a range of different fields including psychoanalysis, philosophy, neuroscience, consciousness studies, trauma therapy, sex therapy, gender theory, disability studies and trans studies, it illustrates how informed clinical practice can recognise the complexity of gender identity and expression. With chapters on the understanding of core gender through the Free Energy Principle, the foundations of gender in consciousness, a gender algorithm, trauma, mirroring, and sexual functioning, this book works to provide a superior method of clinical practice that can better serve trans communities and our understanding of gender across the population.


Most literature for therapists about transgender mental health focuses on cultural competency. This book goes beyond "Trans 101," exploring in much more depth the development of the gendered self and the role of gender in consciousness. With roots in both psychoanalytic and academic worlds, Langer provides clinicians with new ways of theorizing gender that both benefit from these traditions and push them forward.

This book will be essential to both new and seasoned clinicians working with transgender communities. Langer expands our understanding of transgender experience from an interdisciplinary approach. The in-depth chapters of trauma, sex and development are a unique examinations of these clinical issues and their relation to trans experience. The theory and practice in this book contributes to clinical psychology, trans studies, consciousness studies, sex therapy and trans health.

S.J. Langer has generated intriguing ideas that will be of immediate interest to the interdisciplinary field of trans* studies. Beyond essentialist trapping and visual policing of identities, he theorizes transgender experience as a synesthetic "surprise" that involves a complex interaction between one's perceptions of internal biophysiology and their responses to social mirroring.
