Does the chance of getting pregnant increase after having an IUD in for five years if it has not been replaced?
The chance of getting pregnant does not increase with time of use. Evidence from the World Health Organization (WHO) study has confirmed excellent efficacy for at least 12 years. (Readers should be aware that the United States Food and Drug Administration (FDA) has only labeled the copper IUD as effective for only 10 years. Note that some of the documents within the IUD Toolkit may cite the effectiveness of the IUD as 10 years; however, the IUD Toolkit guidance is that it is “effective for at least 12 years”).
