Could a laser ease painful sex for millions of women?
NCT ID NCT05597358
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether high-intensity laser therapy (HILT) can reduce pain during intercourse for women with provoked vestibulodynia, a condition causing severe pain at the vaginal opening. About 145 women with moderate to severe pain will receive either real or sham laser treatments twice a week for six weeks. Researchers will measure changes in pain, sexual function, and quality of life up to six months after treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- High Intensity Laser Therapy (Nd:Yag 1064 nm)
- What this could lead to
- If effective, this could offer a non-drug, non-surgical option to reduce pain during intercourse for women with provoked vestibulodynia.
- What could go wrong
- This is a relatively small trial (145 participants) testing a device, and the sham group may also show improvement due to placebo effects. Long-term benefits are not yet known.
