First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether women who have never given birth (nulliparous) feel more pain during IUD insertion than those who have (multiparous). 162 women rated their pain on a 0-10 scale at different steps of the procedure. The goal is to better understand and manage pain for all women.
