Detailed Description
Gender-affirming hormone treatment impacts myriads of body functions, from which it has to be assumed that only a minority has already been elucidated so far.
This project aims to investigate the consequences and health-related outcomes of various hormone therapies in the treatment of gender dysphoric patients.
The main scientific interest lies in the research of the effects of sex hormones on psychological, metabolic and behavioural parameters.
For this purpose, various investigations are aimed at, including a clinical-diagnostic interview (external rating) and psychometric measurements in self-rating, behavioral experiments (e.g. in a virtual reality Elevated Plus Maze and the computer-based Ultimatum Game) and genetic investigation of the body's own materials (blood samples, stool samples, hair samples and saliva samples).
The results of this study should form the basis to better understand consequences of the long-term administration of sex hormones.
