ED is the inability to develop and maintain an erection for satisfactory sexual intercourse or activity. ED is a highly prevalent medical condition often associated with multiple causes. It is estimated that more than 50 million American men suffer from mild/moderate to severe ED. Roughly 50% of men in their 50's, 60% of men in their 60's, and 70% of men in their 70's suffer from ED. The economic impact of ED is in the billions of dollars. More than 5 billion dollars a year are spent on the pro-erectile medications currently in the market.
Penile vibratory stimulation mimics rapid and repetitive manual/hand stimulation of the penis. Vibratory stimulation of genitalia is considered safe by the medical community with important benefits including treatment of orgasmic dysfunction and stress urinary incontinence. No significant physical or emotional side-effects have been reported in the medical literature. A recent epidemiological study of the use of vibrators by American women and men has shown no complaints, and generally high satisfaction and improvement in sexual response.
Penile erection is controlled by spinal autonomic centers, the activity of which is dependent on input from supraspinal centers and the genitalia. From a neurophysiological viewpoint, scientists believe that penile erection is a culmination of multiple successful nerve reflexes that initiate a vascular event. Simultaneous vibratory stimulation of both surfaces of the penis at high frequency (70-110 Hz) for 7-10 minutes can lead to gradual filling of the penis with arterial blood within minutes by activating the pudendo-cavernosal reflex. Additional physiological effects include progressive rhythmic contraction of the perineal muscles via the bulbocavernosus reflex, which helps in strengthening rigidity of erection. This will prepare the user for successful sexual intercourse. Subsequent orgasm and ejaculation can be very strong and amplified due to stronger contraction of the bulbospongiosus muscle and activation of higher ejaculatory centers.
This study will assess daily or on-demand ease of use, safety, satisfaction, and efficacy of the home use of the Food and Drug Administration (FDA) cleared Viberect device by men with mild to moderate ED
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||50 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Clinical and Physiological Assessment of Noninvasive Penile Afferent Vibratory Stimulation of Both Surfaces of the Penis Using the Viberect® Device in Men With Mild to Moderate ED|
|Actual Study Start Date :||March 2013|
|Estimated Primary Completion Date :||July 2020|
|Estimated Study Completion Date :||July 2020|
Experimental: men with mild to moderate ED
Participants in this arm have documented mild to moderate ED of organic etiology and will be given the Viberect device for 4 weeks of daily home use in preparation for sexual activity. Men will be asked to use the device and attempt sexual intercourse at least 3 times weekly
Men will be asked to perform vibratory stimulation of the penis in the privacy of their home, while focused on sexual thoughts for approximately 7-10 minutes (depending on erectile response) for 3 times a week, one day apart, throughout the four week period. Men can perform the stimulation once daily, as long as each session is more than 24 hours apart.
Men will record device use and intercourse attempts after device use in a diary.
- change in erectile function (EF) [ Time Frame: baseline to 4 weeks post intervention ]The International Index for Erectile Function (IIEF) questionnaire will be administered. This is a 15 item tool; 6 ask questions addressing Erectile function over the previous 4 weeks. Scores from 0-30 can be obtained in this domain. Scores are interpreted as follows: 0-6 = Severe dysfunction, 7-12 = Moderate dysfunction, 13-18 = mild-moderate dysfunction, 19-24 = mild dysfunction, 25-30 = No dysfunction
- change in EF [ Time Frame: baseline to 4 weeks post intervention ]The Erectile Hardness Score (EHS) questionnaire will be administered. it is a single item tool. It is scored from 1 to 4. 4 indicates attainment of full rigidity with ability to perform penetrative intercourse
- Assessment of ease/acceptability of use of the Viberect as assessed by EDITS questionnaire [ Time Frame: 4 weeks post intervention ]The Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire will be administered. This is an 11 item tool addressing participant satisfaction with the Viberect. Each item is a 5-point Likert-type scale from 0 "no satisfaction or dissatisfaction" to 4 "high satisfaction." The overall score is the mean of all answered items multiplied by 4. Total scoring ranges from 0-100 with higher scores indicating higher treatment satisfaction.
- Acceptability of use of the Viberect as assessed by TSS [ Time Frame: baseline to 4 weeks post intervention ]The Treatment Satisfaction Scale (TSS) questionnaire will be administered. This is a 21 item tool addressing participant satisfaction with the Viberect; higher scores indicate greater dissatisfaction
