Intrauterine Device

The insertion of a device into the female reproductive tract goes back hundreds of years. One such object is the intrauterine device (IUD), the "modern" form of which has been around for almost 100 years. Until 1986, the intrauterine device was popular, but it was removed from the market because of many lawsuits against A. H. Robbins Company. The IUD has recently reappeared on the market. There are basically two types of IUD, one contains copper and the other contains prostagen. The intrauterine device is more than 98% effective. There are numerous mechanisms by which the IUD is believed to work.
