Dyspareunia is defined as pain with penetrative sexual intercourse. Women with endometriosis have a nine-fold increased risk of dyspareunia, when compared to the general female population.
A prospective single-blinded randomized controlled trial will be performed evaluating the change in pelvic pain and sexual satisfaction scores from baseline to 6 weeks after treatment with transvaginal photobiomodulation therapy or sham therapy. Treatment will involve 9 planned treatment sessions over 3-4 weeks. 40 women will be included in the study.
Active intervention: Transvaginal photobiomodulation (TV-PBM) Control intervention: Sham transvaginal probe
All subjects will complete 9 treatments over 3-4 weeks and all treatments will be performed with a sheet over the patient's pelvic area to prevent the subject from seeing the probe light, as well as a screen blocking the patient's view of the machine. Subjects randomized to active therapy will undergo TV-PBM treatment during each session per standard TV-PBM treatment protocol. Subjects randomized to sham will undergo blinded sham therapy using an identical probe but without photobiomodulation. Sham therapy will involve the same regimen as the active arm but with the machine turned off. Instead, there will be a recording of the usual noise of the machine to mimic the activation that occurs when stepping on the pedal with the machine on for TV-PBM treatment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Transvaginal photobiomodulation | Active Comparator | Participants will undergo active transvaginal photobiomodulation therapy per clinic protocol, using the SoLa Pelvic Therapy system. This includes 9 treatments, each lasting about 3-5 minutes. A sterile narrow vaginal probe is inserted into the vagina, the low-level laser is activated, and the probe is slowly moved along the vaginal walls for the indicated period of time, via a surface area power calculation based on the measured vaginal length at the beginning of the procedure. The 9 treatments must be completed in 3-4 weeks. Intervention: Active SoLa Low-level laser therapy |
|
| Sham treatment | Sham Comparator | Participants will undergo sham transvaginal photobiomodulation therapy, following the same protocol as the active arm, without activation of the machine. This includes 9 treatments, lasting 3-5 minutes each. A sterile narrow vaginal probe is inserted into the vagina, the machine is NOT activated, and the inactive probe is slowly moved along the vaginal walls for 3-5 minutes. The 9 treatments must be completed in 3-4 weeks. Intervention: Mock treatment with inactivated probe |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Transvaginal photobiomodulation | Device | Low light laser therapy applied transvaginally using a small vaginal wand with sterile disposable wand covers. The intervention last 3-5 minutes based on a surface area calculation performed at the beginning of the intervention, and involves a gentle in and out motion of the wand to deliver light energy to the muscles of the pelvic floor. |
| Measure | Description | Time Frame |
|---|---|---|
| Mean change in pelvic pain | Defined by mean change in 10-point Numerical pain rating scale (NPRS) from baseline scores, compared between treatment and sham control arms | Measured at baseline, after 4th treatment, 1-2 weeks after completion of treatment, and 6 weeks after completion of treatment |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Female Sexual Function Index (FSFI) scores | FSFI is a self-report questionnaire addressing six categories that contribute to female sexual satisfaction: desire, arousal, lubrication, orgasm, satisfaction, and pain. | Measured at baseline, after 4th treatment, 1-2 weeks after completion of treatment, and 6 weeks after completion of treatment. |

| Sham therapy | Device | Use of the same vaginal wand as active arm, but without activation of the machine. The intervention last 3-5 minutes, and involves a gentle in and out motion of the wand to massage the muscles of the pelvic floor, without delivery of light therapy. |

| Change in Short Form-McGill Pain Questionnaire (SF-MPQ) | SF-MPQ is a self-reported questionnaire to help describe pain character and intensity. It consists of 15 descriptors (11 sensory; 4 affective) which are rated on an intensity scale as 0 = none, 1 = mild, 2 = moderate or 3 = severe. Three pain scores are derived from the sum of the intensity rank values of the words chosen for sensory, affective and total descriptors. | Measured at baseline, after 4th treatment, 1-2 weeks after completion of treatment, and 6 weeks after completion of treatment. |
| Change in number of Sexually Satisfying Experiences (SSE) | A 2 question form asking number of SSEs in the past 7 days and the past 1 month. An SSE is defined as: a sexual experience in which you are satisfied with those factors that are most important to you. The experience can be with a partner or alone. | Measured at baseline, after 4th treatment, 1-2 weeks after completion of treatment, and 6 weeks after completion of treatment. |
| Change in clinic pain scores | A standardized pelvic exam to evaluate each muscle group in abdomen and pelvis with a patient assigned pain score (0-10) to each area palpated. | Measured at baseline, after 4th treatment, 1-2 weeks after completion of treatment, and 6 weeks after completion of treatment. |
