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.
