Pathways for Patient-centered Diagnosis and Management of Endometriosis-associated Deep Dyspareunia
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the acceptability and effectiveness of two tools that may help address the management of deep dyspareunia: 1) A phallus length reducer (PLR, brand name: Ohnut), consisting of 4 interconnected silicone rings worn externally over the penetrating object to reduce pain with deep penetration by allowing adjustable limitation of penetration depth, and 2) A vaginal insert for at home self-assessment of the extent and severity of deep dyspareunia.

Detailed Description
Background: Endometriosis is a gynecological condition characterized by the abnormal growth of endometrial like tissue outside of the uterus. The condition affects approximately 10% of reproductive-age females and can cause various types of pain, including chronic pelvic pain and deep dyspareunia (pelvic pain with deep sexual intercourse). Research has shown that individuals with endometriosis and dyspareunia have significantly reduced sexual quality of life, lower self-esteem, and impaired sexual function. Qualitative research has also demonstrated that many individuals with dyspareunia feel guilty about their pain, and often continue to engage in intercourse even when the pain is severe.
Aims and Hypotheses:
-
To measure the reduction in deep dyspareunia observed among people using the PLR with their partner. The investigators hypothesize that the PLR will be associated with a reduction in self-reported deep dyspareunia scores among participants randomized to the PLR intervention, compared to participants randomized to the waitlist control group. The measured reduction in deep dyspareunia will be used to power a future definitive trial.
-
To assess the acceptability of the phallus length reducer (PLR) for participants with endometriosis and their partners. The investigators hypothesize that both partners will indicate the PLR is acceptable on the self-reported questionnaire.
-
To explore whether an at-home assessment of dyspareunia is an acceptable and valid alternative to clinical measures. The investigators hypothesize that the at-home assessments of dyspareunia will be acceptable to participants and will yield results that are highly correlated with questionnaire-based and clinical assessments of this pain.

Outcome Measures
Primary Outcome Measures
- Acceptability of the phallus length reducer (PLR) [After 6 weeks of using the PLR]
Acceptability of the PLR as measured via questionnaire using a 5 point likert scale (1 = most negative/ worst/ strongly disagree, 5 = most positive/ best/ strongly agree)
Secondary Outcome Measures
- Severity of dyspareunia [Measured at baseline, before and after 6 weeks of using the PLR]
Self reported on an 11-point numeric rating scale (0 being no pain, 10 being worst pain imaginable)
- Change in sexual function [Measured at baseline, before and after 6 weeks of using the PLR]
Change in sexual function as measured by Female Sexual Function Index (FSFI). This a brief, self-administered questionnaire to assess key dimensions of sexual function in women. The scale consists of 19 items that assess sexual function over the past four weeks and are scored from 1 to 5 (with 1 being the lowest report of desire and 5 being the highest).
- Change in sexual distress [Measured at baseline, before and after 6 weeks of using the PLR]
Change in sexual distress as measured in Female Sexual Distress Scale-Revised (FSDS-R) This is a self-administered measure of female personal distress associated with sexual dysfunction. There are 13 questions. The range for each question is 0 (Never) to 4 (Always).
- Change in level of general anxiety (GAD-7) [Measured at baseline, before and after 6 weeks of using the PLR]
Change in level of general anxiety as measured using the General Anxiety Disorder - 7 questionnaire. There are 7 questions. The range for each question is 0 (not at all) to 4 (nearly every day).
- Change in level of general depression (PHQ-9) [Measured at baseline, before and after 6 weeks of using the PLR]
Change in level of general depression as measured using the Patient Health Questionnaire- 9 questionnaire. There are 9 questions. The range for each question is 0 (not at all) to 4 (nearly every day).
- Acceptability of self-measurement of dyspareunia [After patient self-measurement of dyspareunia is complete (2 times during study)]
Acceptability of self-measurement of dyspareunia will be measured via questionnaire using 5 point likert scale (1 = most negative/ worst/ strongly disagree, 5 = most positive/ best/ strongly agree)
- Validity of self-measurement of dyspareunia [Assessment and questionnaire administered 2 times, each one week apart, during the first 4 weeks of the study (to be assessed at week 2 and 3 of participant's menstrual cycle, which may vary)]
Dyspareunia score from the self-measurement will be compared to records of dyspareunia scores from physician performed pelvic exams. (11 point scale, 0 being no pain, 10 being worst pain imaginable)
