The influence of cross-sex hormone treatment on brain lateralisation in persons with Gender Dysphoria
Tess Beking

I am a PhD student at the University of Groningen, in cooperation with the VU Medical Center in Amsterdam. My research project is very interdisciplinary, I work at Neuropsychology, Behavioural Biology, Neuroimaging, and sometimes at the Center of Expertise on Gender Dysphoria in Amsterdam. In my project I investigate the effect of sex hormones on brain lateralization in two ways: 1) I investigate the influence of prenatal (measured in amniotic fluid) and pubertal sex hormones in healthy children of 15 years old, 2) I investigate the effect of cross-sex hormone treatment in adolescents diagnosed with Gender Dysphoria.
Background
We investigate the influence of cross-sex hormone treatment on brain lateralisation in adolescents with Gender Dysphoria (>16 years of age). Brain lateralisation is the functional specialization of the brain, with some... [ view full abstract ]
Aim(s)
A very interesting case (and perhaps the only way) for the experimental study of effects of testosterone on lateralisation in humans, is the hormonal treatment in persons with Gender Dysphoria (GD). [ view full abstract ]
Methods
We will investigate the effect of testosterone administration in 21 transboys (FtM). Brain lateralisation is measured with fMRI during the Mental Rotation task. This task is generally lateralised to the right hemisphere. The... [ view full abstract ]
Main Outcome Measures
Lateralisation of brain activation before and during cross-sex hormone treatment will be compared, also in comparison to the control groups. [ view full abstract ]
