Is psychotherapeutic treatment powerless in the case of transsexualism? This intriguing volume by a French psychoanalyst with extensive experience of working with transsexuals is a useful addition to the debate on transsexualism and the definitions of sex and gender. Transsexuals feel that the opposite sex to their biological sex is their true identity - their true body and self. The idea of "hormonal and surgical sex reassignment" appeals to them; it would biologically put right what they already know to be right and true in their minds. The author discusses the problems of "reassigning" one?s sex and argues that surgery alone cannot fix the situation.
