Abstract
There is preliminary evidence that high-frequency repetitive transcranial magnetic stimulation targeting the right dorsolateral prefrontal cortex (DLPFC) could reduce cue-induced sexual arousal. Here, we aimed to replicate this finding by using transcranial direct current stimulation (tDCS). In a randomized, double-blind, sham-controlled crossover study design, 24 healthy male participants received anodal tDCS over right DLPFC, anodal tDCS over left DLPFC, and sham tDCS with exposure to neutral and sexual video cues before and after each intervention. None of the interventions significantly reduced subjective sexual arousal. Stimulation parameters should be varied in further studies to identify factors relevant to the intended effect.
