Global olfactory function correlates with global sexual functioning in men and women.

Area of Science:

• Neuroscience
• Human Sexuality
• Sensory Perception

Background:

• Olfaction plays a role in reproductive behaviors.
• Limited understanding of the link between olfactory and sexual functioning, especially gender differences.
• Investigating olfaction's relation to sexual function, disgust, and illness perception.

Purpose of the Study:

• To explore the correlation between olfactory function and sexual functioning in healthy young adults.
• To examine secondary associations with disgust, perceived vulnerability to illness, and sexual attitudes.
• To determine if gender modulates the relationship between olfaction and sexual function.

Main Methods:

• 125 healthy participants (51 males, 74 females) aged 28.47±8.6.
• Olfactory sensitivity assessed using the Sniffin' Sticks Test (SST).
• Evaluated sexual function (FSFI, IIEF), sexual attitudes (SAS), disgust (BODS), and perceived vulnerability to disease (PVD).

Main Results:

• Positive correlation found between olfaction and sexual function in both sexes.
• In males, better olfaction correlated with higher erectile function (IIEF) and lower BMI/age.
• In females, olfaction correlated with most sexual function domains (FSFI) except sexual desire.

Conclusions:

• Olfactory capacity is positively associated with sexual behavior in both men and women.
• Male sexual function correlations were influenced by age and BMI.
• Female sexual function, excluding desire, correlated with olfaction, suggesting distinct neural pathways for sexual desire.
