Differences in Perceived and Physiologic Genital Arousal Between Women With and Without Sexual Dysfunction

Area of Science:

• Sexual psychophysiology
• Women's sexual health

Background:

• Previous studies found no differences in physiologic genital arousal between women with and without sexual dysfunction.
• However, differences in perceived genital arousal have been noted between these groups.

Purpose of the Study:

• To determine if women with and without sexual dysfunction differ in physiologic and perceived genital arousal.
• To explore differences in perceived genital arousal.
• To assess the relationship between physiologic and perceived genital arousal.

Main Methods:

• Analysis of data from 5 studies (N=214) involving women with arousal-specific sexual dysfunction, decreased sexual function, and sexually functional women.
• Physiologic genital arousal measured via vaginal photoplethysmography during erotic film viewing.
• Perceived genital arousal assessed through self-report measures post-viewing.

Main Results:

• Hierarchical linear modeling revealed significant differences in vaginal pulse amplitude (VPA) and its association with perceived genital sensations based on sexual function levels.
• Women with arousal-specific dysfunction initially showed lower VPA but aroused faster, reaching similar VPA levels as sexually functional women.
• Sexually functional women reported the highest perceived genital responses; no significant link between VPA and perceived arousal was found.

Conclusions:

• Distinct arousal response trajectories exist between women with and without sexual dysfunction.
• Perceived genital responses are crucial for women experiencing arousal issues, potentially more so than objective measures of genital blood flow.
