Özet
Objectives. - The aim of the study was to investigate sensory information processing induced by visual sexual stimuli and to assess its relationship with sexual behaviors and symptoms in patients with vaginismus. Methods. - Twenty-one patients with vaginismus and 20 controls were included in the study. The sociodemographic information and sexual life history of the patients with vaginismus and controls were examined and electrophysiological measurements related to auditory P50 sensory gating were obtained using a double click paradigm during by sexual/horror visual stimulation, which was thought to be related to the pathophysiology of the disease. Results. - P50 suppression ratios during visual sexual stimuli were lower in vaginismus group compared to the control group. There was no difference in P50 suppression ratios during visual horror stimuli when the two groups were compared. The P50 suppression of the vaginismus group with visual sexual stimuli was found to be lower than P50 suppression with visual horror stimuli. A positive moderate correlation was found between the duration of foreplay and P50 suppression ratio during visual sexual stimuli in vaginismus group. Conclusion. - Our study revealed that patients with vaginismus had sensory gating impairment during visual sexual stimuli. Increase in the duration of foreplay in vaginismus patients may improve sensory gating impairment by affecting sensory gating functions. (C) 2021 Elsevier Masson SAS. All rights reserved.
