The defective copper IUD is called Novaplus T380. Almost six thousand people in Skåne received this particular copper IUD. Every tenth copper IUD has broken, often when being removed from the womb. Region Skåne stopped using this type of copper IUD as soon as it was discovered that they were faulty.
No one was hurt by the faulty copper IUDs. However, some did become pregnant. It is unknown whether this was by chance or if it was due to the faulty copper IUD. Normally, very few people using copper IUDs become pregnant. Even so, there are no contraceptives that offer a 100% protection against pregnancy.
