A double-blind, triple-arm randomized controlled trial of 1% lidocaine paracervical block for intrauterine device (IUD) insertion

Findings from this randomized, double-blind trial support incorporating the paracervical block into routine IUD insertion, especially for nulliparous patients who experience higher pain. Wider adoption may improve procedural comfort, satisfaction, and acceptability of IUD use. Future research should evaluate implementation, patient preferences, and variations in technique.
