IUD (intrauterine device)

Also known as: Coil, intrauterine device

Medically reviewed, last updated

An IUD is a small T-shaped device placed in the uterus to prevent pregnancy. Two types: hormonal (Mirena, Kyleena, Liletta, Skyla) and copper (Paragard). Hormonal IUDs last 3-8 years depending on brand; copper IUDs last up to 12 years. Both are 99%+ effective at preventing pregnancy.

IUDs require in-office placement; pain management options have improved as patient advocacy has documented severe placement-pain experiences, including specifically among Black patients whose pain reports have been historically minimized. Ask about pain-management options (oral pain medication, paracervical block, anxiolytic premedication) BEFORE the procedure.
