Hyposmia and Disgust: Gender-Specific Effects

Area of Science:

• Neuroscience
• Psychology
• Sensory Science

Background:

• Reduced olfactory function (hyposmia) is linked to changes in trait disgust, particularly in men.
• Previous research indicates a connection between olfactory deficits and altered disgust responses.

Purpose of the Study:

• To investigate whether women with hyposmia exhibit similar alterations in disgust responsiveness as observed in men.
• To compare disgust proneness, self-disgust, and disgust sensitivity between individuals with and without hyposmia, examining gender differences.

Main Methods:

• Compared 48 patients with hyposmia (25 men, 23 women) to 50 normosmic controls (25 men, 25 women).
• Assessed disgust proneness across domains, self-disgust, and disgust sensitivity (control and embarrassment).

Main Results:

• Male patients with hyposmia reported higher self-disgust and disgust proneness (poor hygiene domain) than male controls.
• Female patients with hyposmia showed comparable disgust scores to female controls.
• Both male and female patients with hyposmia reported difficulties regulating disgust in social contexts.

Conclusions:

• Hyposmia is associated with greater alterations in trait disgust in men compared to women.
• The observed gender-specific effect may be due to more effective compensatory behaviors in women.
• Further research is needed to explore the mechanisms behind these gender differences in hyposmia-related disgust changes.
