Light therapy inside the body: a new hope for chronic pelvic pain?
NCT ID NCT06673108
First seen Aug 25, 2026 · Last updated Aug 26, 2026 · Updated 1 time
Summary
This trial tests whether eight sessions of vaginal photobiomodulation—using near-infrared laser energy—can reduce chronic pelvic pain in women. Participants must have had pelvic pain for at least three months and report moderate to severe pain. The study compares the laser treatment to a sham (visible light without laser energy) to see if the real treatment eases pain during daily activities like sitting, standing, and intercourse.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vaginal photobiomodulation using near-infrared laser energy delivered via a sterile probe
- What this could lead to
- If effective, this could offer a non-drug, non-surgical option for women with chronic pelvic pain, potentially easing pain during daily activities and intercourse.
- What could go wrong
- This is a phase 2 trial, so results are preliminary. The sham control uses visible light, which may not fully blind participants, and the treatment requires multiple sessions, which may not suit everyone.
