"Sex Changes: The Politics of Transgenderism is Califia's meticulously researched book based on an astute reading of the available literature and in-depth interviews with gender transgressors who "opened their lives, minds, hearts, and bedrooms to the gaze of strangers."
Writing about both male-to-female and female-to-male transsexuals, Califia examines the lives of early transgender pioneers like Christine Jorgensen, Jan Morris, Renee Richards, and Mark Rees, contemporary transgender activists like Leslie Feinberg and Kate Bornstein, and partners of transgendered people like Minnie Bruce Pratt. Califia scrutinizes feminist resistance to transsexuals occupying women's space, the Christian Right's backlash against transsexuals, and the appropriation of the berdache and other differently-gendered by gay historians to prove the universal existence of homosexuality. Finally, Sex Changes explores the future of gender."
