The influence of cross-sex hormone treatment on brain lateralisation in persons 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 ]

Main Outcome Measures

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 ]

Methods

Lateralisation of brain activation before and during cross-sex hormone treatment will be compared, also in comparison to the control groups. [ view full abstract ]
