This comprehensive text is one of the first to tackle the grave matter of the sexual abuse of boys, in all its complexity, within a biopsychosocial context and from different vantage points. Based on the life histories of more than one thousand sexually abused boys and adult males with histories of childhood sexual abuse, SexualAbuse of Males examines the myriad biological, psychological, interpersonal, familial, and social variables that underlie and impact the experience of childhood sexual abuse. Guided by research and informed by practice, this pioneering text presents an extensive review of the literature, a well-grounded theoretical model of abuse dynamics and effects, a systematic model of treatment. This information is further elucidated through compelling case illustrations that highlight the effects of sexual abuse with regard to biological, psychological, and social adaptation, and development.
