Visual Erotica, EMG, and Sexual Psychophysiological Arousal (VESPA)

This study will examine whether measurement of pelvic floor muscle sEMG activity is responsive to explicit sexual stimuli, and whether it correlates with self-reports of sexual arousal in healthy women. Participants' vaginal, labial and anal sEMG readings will be monitored during exposure to neutral, erotic and anxiety-provoking films. Participants will also be required to provide subjective ratings of sexual arousal before and after each film. If pelvic floor sEMG is validated as a psychophysiological measure, these findings may have important clinical and research implications by providing a greater understanding of the mechanisms involved in sexual arousal and for providing a relatively easy method of assessing sexual arousal in a clinical or research setting.

About this study

HYPOTHESES:

  • Investigators hypothesize that, relative to the neutral films, PFM EMG activity will significantly increase in response to the erotic film as measured by the labial, anal, and vaginal EMG probes.
  • Investigators hypothesize that, relative to the anxiety-provoking film, PFM EMG activity will significantly increase in response to the erotic film as measured by the labial, anal, and vaginal EMG probes.
  • Investigators hypothesize that continuously measured subjective sexual arousal (via the arousometer) will correlate significantly with PFM EMG activity during the erotic film.

Treatment and study plan

Primary outcomes

  1. Pelvic floor muscle sEMG activity

    Time frame: This study involves 1 testing session approximately 20 minutes in duration

    Changes in pelvic floor muscle activity in responsive to exposure to explicit sexual stimuli will be assessed using pelvic floor surface electromyography (sEMG).

Secondary outcomes

  1. Sexual Arousal

    Time frame: This study involves 1 testing session approximately 20 minutes in duration

    Self-report sexual arousal will be measured with the Sexual Arousability Inventory (SAI ; Hoon, Hoon, & Wincze, 1976)

  2. Sexual Function

    Time frame: This study involves 1 testing session approximately 20 minutes in duration

    Self-reported sexual function will be measured using the Female Sexual Function Inventory (FSFI; Rosen et al., 2000) and the Derogatis Sexual Functioning Inventory (DSFI; Derogatis & Melisaratos, 1979).
