Natural oil vs. drug: which prepares the cervix better for surgery?
NCT ID NCT07641595
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared evening primrose oil (a natural oil) with misoprostol (a standard drug) for softening the cervix before operative hysteroscopy. 230 women participated. Researchers measured how easily the cervix could be dilated and noted any complications like bleeding or tears. The goal was to see if the natural oil could be a gentler alternative.

- Active substance
- evening primrose oil and misoprostol
- What this could lead to
- If evening primrose oil works as well as misoprostol, it could offer a more natural option for preparing the cervix before hysteroscopy.
- What could go wrong
- This is a small, completed study. Results may not apply to all patients, and evening primrose oil might be less effective or cause side effects.
