ParaGard, Liletta, Mirena, Skyla, and Kyleena.
They're divided into 2 types: Copper IUDs (ParaGard) and hormonal IUDs (Liletta, Mirena, Skyla, and Kyleena).
The Copper IUDs are wrapped in a tiny bit of copper, and it protects you from pregnancy for up to 12 years, it doesn't contain hormones.
The Hormonal IUDs use the hormone called "progestin" to prevent pregnancy. This hormone is similar to the hormone progesterone, which our bodies make naturally. Mirena works up to 6 years, Kyleena 5 years, then Skyla & Liletta 3 years.
