Could a simple injection ease pain during fertility testing?
NCT ID NCT07048769
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study investigates whether a local anesthetic (lidocaine) injected near the cervix can reduce pain during a saline infusion sonogram, a routine fertility test that evaluates the uterus and fallopian tubes. About 246 women undergoing this procedure will be randomly assigned to receive either lidocaine or a sham block (a capped needle pressed without injection). Their self-reported pain scores will be compared to see if the anesthetic improves comfort.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lidocaine
- What this could lead to
- If effective, this could make saline infusion sonograms less painful and more accessible for women undergoing fertility evaluations.
- What could go wrong
- This is a single-site trial with 246 participants, and the benefit may be modest or not statistically significant. Lidocaine injections can cause temporary discomfort or rare side effects like allergic reactions.
