People with gender identity problems are increasingly often encountered by health professionals. The problems are often imagined to consist only of transsexuality, but actually comprise of both this and many other diagnoses. Properly establishing a diagnosis and excluding alternatives including psychosis, partial androgen insensitivity syndromes and personality disorder is complex. The subsequent management of these disorders and their differential diagnoses is even more so. The text provides a comprehensive and extremely practical account of the management of disorders of gender identity and their differential diagnoses. Particular consideration is given to, among others, coincidental mental illness, disability, family and relationship issues, forensic and military settings. Psychological and endocrine aspects are covered in depth, surgical aspects to a level adequate for all but a specialist surgeon, and legal aspects to the level generally needed by health professionals. This book provides vital detail for general practitioners, surgeons, endocrinologists, speech therapists, social workers and, especially, psychiatrists.
