The thesis deals with the differences between Female-to-Male (FtM) and Male-to-Female (MtF) transsexuals, focusing on their intelligence and personality traits. The aim of the study was to compare the results between male and female transsexuals in these two areas and to recognize if the distribution of given personality traits corresponds more to their biological sex or to the gender identity. In the theoretical part of the work, studies about males and females in the population are presented and put into a broader context of the studies concerning FtM and MtF transsexuals, while using all accessible literature. The research comprises of data comparison of 200 transsexuals (100 MtF and 100 FtM) using Raven's Progressive matrices and DOPEN questionnaire. The results were evaluated by the statistical analysis and were later compared to the norms for men and women in population. There were found no differences in intelligence in both groups of transsexuals. Both groups' intelligence (IQ 117) is slightly above-average. Using the Raven's Progressive matrices, higher variability of results was measured in the MtF group. Male-to-Female transsexuals reached significantly higher scores in neuroticism compared to Female-to-Male group. This scale was identified as significantly higher in both groups when...

The master thesis copes with gender dysphoria (GD) in persons with autism spectrum disorder (ASD). The quantitative research was chosen to study this topic. The main goal was to determine whether people with mild ASD have a higher prevalence of GD or higher rate of GD compared to the general neurotypical population (NT). The main methods used in this research were: Autism Quotient Questionnaire (AQ-10) and the Gender Identity/Gender Dysphoria Questionnaire in Adolescents and Adults (GIDYQ-AA), which made it possible to determine the degree of GD and the potential co-occurrence of a diagnosis of gender incongruence (GI; according to ICD-11). In the research there were 196 subjects with the age ranging from 16 to 74 years. The ASD group was compromised 90 persons and in the NT group there were 106 people. While in the NT group no one admitted transgender identity, in the ASD group 2.2 % of subjects informed about transgender identity and 14.4 % of the autistic group were not sure about it. Based on the GIDYQ-AA results, 4.4 % of people with ASD had a low score indicating a possible presence of a diagnosis of GD (GI). Furthermore, the research found that women with autism had significantly higher rate of GD than both women in the NT group and men with ASD. Overall, subjects with ASD achieved...
