Does the non-hormonal/copper IUD (Paragard) cause copper toxicity?

I heard the non-hormonal IUD can cause copper toxicity.

IUDs are safe for most people with a uterus, and copper toxicity is super rare. That said, it can happen, especially in people with Wilson’s Disease, a rare genetic condition (about 1 in every 30,000 to 40,000 people have it) that affects your body’s ability to process copper. Given how low the daily dose of copper is from the non-hormonal IUD, it is extremely unlikely that someone who does not have Wilson’s Disease would experience copper toxicity.
