This thesis reports an interview-based study of thirty female-to-male (FtM) transsexual individuals. These participants were divided into three groups of ten according to their transitional status: 'pre-transitional', 'transitional and 'post-transitional. Interviews were carried out utilising an extensive semi-structured interview schedule and were recorded. Tapes together with field notes from each interview were that transcribed. The thirty transcripts were then subjected to a detailed review and analysis. A range of issues were identified in relation to the notion of FtM transsexual identity as this was experienced through the processes of FtM transition. The conclusions drawn identified a number of substantive areas of insight into the FtM transsexual condition, each of which have implications for an understanding of: coping with a threatened identity; passing; trust; factors relating to and effects of disclosure following these individuals' decision to embark cm transition; issues pertaining to transition, and attitudes of the medical profession toward transsexualism, among others. Some policy issues were also identified indicating scope for interentive measures geared at facilitating the life circumstances and transsitional passage of FtM transsexual people.
