A controlled study of psychological and social change after surgical gender reassignment in selected male transsexuals.

Of two groups of 20 patients accepted for gender reassignment surgery, one was offered early operation and therefore had had surgery by follow-up two years later, while the second was still awaiting operation at two-year follow-up. Although the groups were similar initially, significant differences between them emerged at follow-up in terms of neuroticism and social and sexual activity, with benefits being enjoyed by the operated group.
