Detailed Description
Male sexual health is an often overlooked and ignored facet of mens well-being. However, this can have significant effects on quality of life for both the man afflicted by sexual dysfunction as well as their partner. Most commonly we think of erectile dysfunction (ED) as the main factor of male sexual dysfunction, but ejaculatory dysfunction (EjD) and other problems relating to orgasm are also important. EjD is exceedingly common especially in the aging male population, and includes premature ejaculation (PE), delayed ejaculation (DE), anejaculation (absence of ejaculation during orgasm), retrograde ejaculation, and painful ejaculation. Medications such as sildenafil (Viagra) and tadalafil (Cialis) are PDE-5 inhibitors that are commonly used for the treatment of ED, but there are very few medications specifically formulated to treat EjD. More conservative management options for the treatment of ED include vacuum erection devices, psychotherapy, and lifestyle changes. The usual next step after failure of the above options includes intracavernosal injections which involve directly injecting erectogenic medication into the penis, intraurethral injections, or finally surgery. Ejaculatory dysfunction on the other hand, whether it be premature, delayed, retrograde, or anejaculation all have much less treatment options. Most of these include either the off-label use of medications to treat other conditions or sex therapy / psychotherapy.
Treatments including pudendal neuromodulation or pudendal canal decompression have shown significant improvement in ED and EjD. Due to side effects and the lack of patient compliance to oral medication, non-oral medication treatments are in high demand for this condition. Neuromodulation therapies have become increasingly popular for the treatment of male sexual dysfunction. These neuromodulation therapies often work by stimulating the sacral nerve. The Emsella Chair is a conservative neuromodulation therapy that may have a role for patients who are not surgical candidates or who desire a noninvasive treatment option. The Emsella Chair uses high intensity focused electromagnetic (HIFEM) technology to induce deep pelvic floor muscle contractions, the equivalent of 11,200 Kegel exercises over 28 minutes. The treatment awakens deconditioned pelvic floor muscles, delivers the stimulations, and then relaxes the muscles. The repetition of these phases leads to pelvic floor adaptation and remodulation. this treatment could provide similar improvement for men with sexual dysfunction given the significant overlap in anatomy and physiology, as well as studies that have shown improvement in ED with pelvic floor muscle therapy.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Emsella Chair Active Treatment Subjects will be asked to sit on the device and the height will be adjusted until the subject's feet are on the floor. The active treatments are individualized, since some subjects will be more sensitive than others. The Emsella chair will be turned on and the setting gradually increased to the subject's sensory threshold; the maximum sensation the subject can tolerate. The setting will be decreased slightly and stay unchanged for the remainder of the treatment. The treatment threshold should be increased with every treatment until the subject reaches 100%. |
Device: BTL Emsella Chair
Subjects will sit on the device. The RNC will turn the device on and increase the setting gradually until the patient reaches their sensory threshold. This is the maximum sensation the patient can tolerate. The treatment threshold should be increased until the subject reaches 100%.
|
| Sham Comparator: Emsella Chair Sham Treatment Sham treatment subjects will be positioned on the device in the same manner. The sham treatment will provide some sensation without active HIFEM technology. The programming for the sham treatment will have an amplitude limitation, with the setting below the therapeutic level (<10% power). |

Outcome Measures
Primary Outcome Measures
- Compare the efficacy of the Emsella Chair to sham by evaluating subject reported symptom improvement as measured by the Global Response Assessment (GRA) [4 weeks after completing all treatments; week 8 of the study]
The GRA is a validated single question survey prompting subjects to rank change in symptom severity since the start of therapy on a 7-point scale (1 = markedly worse, 2 = moderately worse, 3 = mildly worse, 4 = same, 5= slightly improved, 6 = moderately improved, 7= markedly improved).
Secondary Outcome Measures
- Change in subject-reported ability to achieve an erection as measured by the Male Sexual Health Questionnaire (MSHQ). [4 weeks after completing the primary endpoint; week 12 of the study]
The MSHQ is a validated, self-administered questionnaire which was developed specifically for assessing key aspects of sexual function and satisfaction in the aging male with urogenital health concerns. The MSHQ contains 3 domains: Erection scale (3 items), Ejaculation scale (7 items), and Sexual satisfaction scale (6 items). 9 additional items (2 items measuring bothersome linked to erection and ejaculation and 7 items measuring sexual activity and desire). Specifically item 1 will be reviewed from the erection scale. Measured as (5 = all of the time, 4 = most of the time, 3 = about half of the time, 2 = less than half the time, 1 = none of the time, and 0= used viagra or similar drug with every sexual encounter). A higher score indicates a higher ability to achieve an erection.
- Change in subject-reported ability to maintain an erection as measured by MSHQ responses [4 weeks after completing the primary endpoint; week 12 of the study]
The MSHQ is a validated, self-administered questionnaire which was developed specifically for assessing key aspects of sexual function and satisfaction in the aging male with urogenital health concerns.

Specifically item 2 will be reviewed from the erection scale. Measured as (5 = all of the time, 4 = most of the time, 3 = about half of the time, 2 = less than half the time, 1 = none of the time, and 0= used viagra or similar drug with every sexual encounter). A higher score indicates a higher ability to maintain an erection.
- Change in subject-reported ability to ejaculate as measured by MSHQ responses [4 weeks after completing the primary endpoint; week 12 of the study]

The MSHQ contains 3 domains: Erection scale (3 items), Ejaculation scale (7 items), and Sexual satisfaction scale (6 items). 9 additional items (2 items measuring bothersome linked to erection and ejaculation and 7 items measuring sexual activity and desire). Specifically item 5 will be reviewed from the ejaculation scale. Measured as (5 = all of the time, 4 = most of the time, 3 = about half of the time, 2 = less than half the time, 1 = none of the time/could not ejaculate). A higher score indicates a higher ability to achieve ejaculation.
- Change in subject-reported strength or force of ejaculation as measured by MSHQ [4 weeks after completing the primary endpoint; week 12 of the study]

Specifically item 8 will be reviewed from the ejaculation scale. Measured as (5 = as strong as it always wast, 4 = a little less strong than it used to be, 3 = somewhat less strong then it used to be, 2 = much less strong than it used to be, 1 = very much less strong than it used to be, 0= could not ejaculate). A higher score indicates a higher ability to achieve a forceful ejaculation.
- Change in subject-reported volume of semen when ejaculating as reported on the MSHQ. [4 weeks after completing the primary endpoint; week 12 of the study]
The MSHQ is a validated, self-administered questionnaire which was developed specifically for assessing key aspects of sexual function and satisfaction in the aging male with urogenital health concerns. The MSHQ contains 3 domains: Erection scale (3 items), Ejaculation scale (7 items), and Sexual satisfaction scale (6 items). 9 additional items (2 items measuring bothersome linked to erection and ejaculation and 7 items measuring sexual activity and desire). Specifically item 9 will be reviewed from the ejaculation scale. Measured as (5 = as much as it always was time, 4 = a little less then it used to be, 3 = somewhat less than it used to be, 2 = much less than it used to be, 1 = very much less than it used to be, 0= could not ejaculate). A higher score indicates a higher ability to produce a greater volume of ejaculate.
- Change in subject-reported pleasure with ejaculation as measured by the MSHQ. [4 weeks after completing the primary endpoint; week 12 of the study]

Specifically item 10 will be reviewed from the ejaculation scale. Measured as (5 = increased a lot, 4 = increased moderately, 3 = neither increased nor decreased, 2 = decreased moderately, 1 = decreased a lot, 0= could not ejaculate). A higher score indicates a higher ability report pleasure with ejaculation.
