Background: Gender identity disorder (GID) or gender dysphoria is a disorder in which an individual identifies him/herself with the opposite sex. GID following sex reassignment surgery is usually associated with severe distress and several limitations in the personal and social aspects of life as a transgender.
Objectives: The aim of this systematic review and meta-analysis was to evaluate quality of life after sex reassignment surgery in transgender individuals.
Data sources: A search was conducted in English databases, including PubMed, Scopus, PsycINFO, Science Direct, and Google Scholar, as well as Iranian databases including Iran Medex, MagIran, and SID. In addition, the reference lists of the included articles were reviewed without any time limitations. The final literature search was performed on June 12, 2017.
Study selection: All relevant cross-sectional and observational studies were evaluated in this review. The keywords included: “sex”, “gender”, “reassignment surgery”, “reassignment operation”, “sex change”, “sex reversal”, “transpersonal”, “sexual transition", “gender dysphoria”, “transsexual”, “transgender”, “gender identity”, “male-to-female transsexual”, “female-to-male transsexual”, “quality of life”, “QOL”, “quality adjusted”, and “wellbeing”.
Data extraction: After screening 941 articles, sixteen studies were reviewed systematically, six of which were included in the meta-analysis. Comprehensive Meta-Analysis Software Version 2 was used for all meta-analyses.
Results: Quality of life improved after sex reassignment surgery in some dimensions, including bodily pain, emotional role, and mental health in male-to-female (MtF) transsexuals and physical function and physical role in female-to-male (FtM) transsexuals. Physical role, vitality, and social function in MtF transsexuals were not significantly different from the general population. On the other hand, bodily pain, general health, social function, vitality, mental health, and emotional role in FtM transsexuals, as well as physical function and general health in MtF transsexuals, were lower than the general population.
Conclusion: Based on the findings, sex reassignment surgery could improve some dimensions of quality of life, including bodily pain, emotional role, and mental health in MtF transsexuals and physical function and physical role in FtM transsexuals. Nevertheless, further research is necessary in this area.
