NCT04370444

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.

Outcome Measures

Primary Outcomes (1)

  • Acceptability of the phallus length reducer (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)

    After 6 weeks of using the PLR

Secondary Outcomes (10)

  • Severity of dyspareunia

    Measured at baseline, before and after 6 weeks of using the PLR

  • Change in sexual function

    Measured at baseline, before and after 6 weeks of using the PLR

  • Change in sexual distress

    Measured at baseline, before and after 6 weeks of using the PLR

  • 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 depression (PHQ-9)

    Measured at baseline, before and after 6 weeks of using the PLR

  • +5 more secondary outcomes

Study Arms (2)

Experimental (PLR)

EXPERIMENTAL

Participants will be given the OhNut Phallus Length Reducer (PLR) for use during the study period.

Device: Phallus Length ReducerOther: Self-assessment of dyspareunia

Control (Waitlist)

OTHER

Participants will not have a PLR during the study period. They will be placed on a waitlist to receive the PLR at the end of the study period.

Other: Self-assessment of dyspareunia

Interventions

Also known as: OhNut

Eligibility Criteria

Age19 Years - 49 Years
Sexall(Gender-based eligibility)
Gender Eligibility DetailsParticipants with endometriosis by definition are of the female sex but may self-identify with any gender identity. We are also recruiting their sexual partners, who may be of either sex, any gender identity.
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Patient
  • to 49 years of age
  • Monogamous sexual partnership
  • Sexually active or not sexually active due to deep dyspareunia

  • Sexual partner who is willing to participate
  • Willing to engage in penetrative sex at least once during the duration of the study
  • Partner
  • years of age or older
  • Sexually active with a patient participant who has consented to participate in this study

You may not qualify if:

  • Patient
  • Superficial dyspareunia score ≥ 4/10 (This is a potentially confounding variable; the PLR is not expected to affect introital pain)
  • Current use of a PLR
  • Inability to complete English-language questionnaires
  • GAD-7 score ≥ 15
  • PHQ-9 score ≥ 15
  • Intense fear/anxiety in anticipation of, during, or as a result of vaginal intercourse
