Slide 9

As seen on the previous slide, failure rates vary widely among different contraceptive methods. There is also variability among different types of the same method. For example, as this slide shows, copper IUDs being distributed at this time are very effective. However, the TCu 380A has shown the lowest pregnancy rate of any copper IUD in comparative trials. In FHI clinical trials, failure rates for any of these five IUDs were less than 4 percent after one year of use. However, failure rates among the average population may be slightly higher.

Note that each IUD has a recommended lifespan. This means that the IUD is effective for up to a specific number of years from the date of insertion. For example, if a woman had a TCu 380A inserted today, she would not need to have it replaced or removed for 12 years.
