How does the copper chain work?

For the copper chain, four to six copper cylinders are threaded onto a nylon thread. The number depends on the size of the uterus - the higher the interior of the uterus, the more cylinders can be on thread. They release copper ions, which affect sperm motility so much that they can hardly fertilize an egg. In addition, the copper chain itself acts as a foreign body in the uterus and thus complicates the implantation of a possibly fertilized egg.

How safe is the copper chain?

The effectiveness of a contraceptive method is indicated by the Pearl Index. This states how many women who use a certain contraceptive method for a year still become pregnant. The copper chain has a Pearl index of 0.1 to 0.5. So she is considered a very safe contraceptive. Its effect lasts for about five years.
