A personality study was conducted using Eysenck Personality Inventory (EPI) so as to analyze two aspects of the personality (extraversion and neuroticism). Thirty-eight subjects who had undergone hormonal surgical reassignment were included in the study.
The results show that gender reassignment surgery improves the QoL for transsexuals in several different important areas: most are satisfied of their sexual reassignment (28/30), their social (21/30) and sexual QoL (25/30) are improved. However, there are differences between male-to-female (MtF) and female-to-male (FtM) transsexuals in terms of QoL: FtM have a better social, professional, friendly lifestyles than MtF. Finally, the results of this study did not evidence any influence by certain aspects of the personality, such as extraversion and neuroticism, on the QoL for reassigned subjects.
