Types of IUDs

There are two main types of IUDs: copper IUDs (such as the ParaGard) and hormonal IUDs (like Mirena, Kyleena, Liletta, and Skyla)<ref name="Mayo">

Effectiveness and Side Effects

IUDs are more than 99% effective at preventing pregnancy<ref name="CDC" />. Side effects can include irregular bleeding, headaches, nausea, depression, and acne. In rare cases, the IUD can puncture the uterus upon insertion or can be expelled from the uterus<ref>

History of IUDs

The concept of an IUD dates back to the early 1900s. The first effective and widely used IUD was the Grafenberg ring, developed in the late 1920s. Modern IUDs have been in use since the 1960s<ref name="History">,
