Anxiety induction and sexual arousal in men and women

Abstract

Anxiety can sometimes inhibit and sometimes potentiate sexual arousal. We examined whether an anxiety manipulation in a classical fear-conditioning paradigm impacts self-reported sexual arousal in men and women. University students (62 men, 61 women) underwent differential fear conditioning to erotic images; half the images were sometimes (60%) paired with a shock (CS+) and half were never paired with a shock (CS–). For each trial, participants rated their sexual arousal and anxiety in response to the image; skin conductance response (SCR) and zygomatic and corrugator activity were recorded. During acquisition, self-reported sexual arousal was lower to CS+ than CS− (inhibiting effect), but in men only. During extinction, self-reported sexual arousal was lower to CS+ than CS− for both genders. Some differences produced by CS+ and CS− were observed for SCR and zygomatic and corrugator activation at different points during acquisition and extinction, but the effects were unrelated to ratings of anxiety or sexual arousal. The negative impact of anxiety on sexual arousal appears to be resistant to extinction, and small gender differences were observed. Future studies should include direct measures of physiological sexual arousal. The relationship between sexual arousal and anxiety appears to be complex and should be further investigated.
