Hyposmia and Disgust: Gender-Specific Effects

Abstract

Reduced olfactory function is associated with altered trait disgust in men. This study sought to determine whether hyposmic women show similar changes in disgust responsiveness. We compared patients with hyposmia (25 men, 23 women) and 50 normosmic individuals (25 men, 25 women) with regard to their tendency to experience disgust across different disgust domains (disgust proneness), their self-disgust and their tendency to perceive their own disgust feelings as difficult to control and embarrassing (disgust sensitivity). We replicated the finding that male patients reported elevated self-disgust and disgust proneness toward a specific disgust domain (poor hygiene), whereas female patients obtained comparable disgust scores as the female control group. Both men and women of the patient group indicated disgust regulation difficulties in social contexts. In conclusion, we found greater changes in trait disgust in men with hyposmia. This gender-specific effect, which might be a result of more efficient compensatory behaviors in women, needs further investigation.
