Copper IUDs

Slide 6

This slide shows some of the newer copper IUDs in current use. IUDs are generally characterized in two ways — by their shape and by the materials from which they are made. In the late 1960s, researchers found that adding copper to the plastic frames made IUDs safer and more effective than earlier devices. The copper released into the uterine cavity increases the contraceptive efficacy of the IUD. These newer IUDs are smaller, cause fewer side effects, and are less likely to be expelled than most of the older versions.

Most IUDs being inserted today are shaped like a T with copper wires or bands on the plastic stem and arms. The TCu 380A is currently one of the most widely distributed copper IUDs in the world.

Although some older IUDs are still being used in parts of the world, this presentation will focus on the newer copper-releasing IUDs. At the end of the presentation, we will briefly discuss two IUDs that release hormones instead of copper.
