King making the hormonal IUD slightly more effective.
Copper iud failure rate. ESI and 134 113 158 for copper-IUD vs. The TCu 380A ParaGard has a one year failure rate of 08 and a cumulative 12-year failure rate of 22. A Phase II trial of the VeraCept device involved 286 women at 12 US.
The Open Access Journal of Contraception indicates that failure rate can. About 60 of the women enrolled were nulliparous. According to the Centers for Disease Control and Prevention CDC the typical failure rate of a copper IUD is 08.

3 By comparison the two 52-mg levonorgestrel IUDs have typical use failure rates of 01 per 100 women. The T380A IUD has a typical use failure rate of 08 per 100 women. Over 12 years of use the models with less surface area of copper have higher failure rates.
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. Copper IUDs have a first year failure rate ranging from 01 to 22.
The meta-analyses showed that odds ratio OR of 1-year continuation rate was 155 136 176 for LNG-IUS vs. The TCu 220A has a 12 year failure rate of 58 whereas the TCu 380A has a 12 year failure rate of 22.
