How does the Paragard IUD work?

Paragard works by preventing the sperm from reaching and fertilizing the egg and may also prevent implantation.

Because Paragard is 100% hormone free, it won’t prevent your natural menstrual cycle or stop you from ovulating each month.

At first, periods may become heavier and longer with spotting in between.

Paragard is a hormone-free IUD (intrauterine device) that prevents pregnancy for up to 10 years using copper.


  • Don't use Paragard if you are or may be pregnant, have fibroids, a pelvic infection including pelvic inflammatory disease (PID), get infections easily, certain cancers, unexplained bleeding, Wilson's disease,
