failure rate
Last reviewed 01/2018
Guidance concerning the use of copper intrauterine devices suggest that (1)
- women should be advised of the low failure rate of IUDs, i.e. around 1%
- IUDs containing at least 300 mm2 of copper should be used as they have the lowest failure rates
- IUDs such as T-Safe Cu380A represent a reversible alternative to female
sterilisation
- with a reported 0.6–0.8 pregnancies per 100 women in the first 12 months of use
