Randomized Trial of Clitoral Vacuum Suction Versus Vibratory Stimulation in Neurogenic Female Orgasmic Dysfunction

Published:September 09, 2017DOI:https://doi.org/10.1016/j.apmr.2017.09.001

      Highlights

      • Effective, safe therapies are shown to promote orgasm in women with spinal cord injury (SCI) or multiple sclerosis (MS).
      • Clitoral vacuum suction improved overall sexual function with sustained efficacy.
      • Vibratory stimulation improved orgasmic function during active treatment.
      • Clinicians should make these treatments available to women with MS or SCI.
      • Research should examine benefits of orgasm on spasticity and quality of life.

      Abstract

      Objective

      To examine the safety and efficacy of using a clitoral vacuum suction device (CVSD) versus vibratory stimulation (V) to treat orgasmic dysfunction in women with multiple sclerosis (MS) or spinal cord injury (SCI).

      Design

      Randomized clinical trial.

      Setting

      Two academic medical centers.

      Participants

      Women (N=31) including 20 with MS and 11 with SCI.

      Intervention

      A 12-week trial of the use of a CVSD versus V.

      Main Outcome Measures

      Female Sexual Function Inventory (FSFI) and Female Sexual Distress Scale (FSDS).

      Results

      Twenty-three women (18 MS, 5 SCI) completed the study including 13 of 16 randomized to CVSD and 10 of 15 randomized to V. There was a statistically significant increase in total FSFI score (P=.011), desire (P=.009), arousal (P=.009), lubrication (P=.008), orgasm (P=.012), and satisfaction (P=.049), and a significant decrease in distress as measured by FSDS (P=.020) in subjects using the CVSD. In subjects who used V, there was a statistically significant increase in the orgasm subscale of the FSFI (P=.028). Subjects using the CVSD maintained improvements 4 weeks after treatment.

      Conclusions

      CVSD is safe and overall efficacious to treat female neurogenic sexual dysfunction related to MS and SCI. V is also safe and efficacious for female neurogenic orgasmic dysfunction; however, results were limited to the active treatment period. Because of ease of access and cost, clinicians can consider use of V for women with MS or SCI with orgasmic dysfunction. CVSD is recommended for women with multiple sexual dysfunctions or for whom V is ineffective.
