An IUS that works differently
Mechanism of Action
Paragard® is made mostly of soft, flexible plastic and copper
Paragard has a unique mechanism of action. It uses 1 simple active ingredient—copper—to prevent pregnancy without any hormones.
Copper enhances contraceptive efficacy by:
- interfering with sperm transport and fertilization
- possibly preventing implantation
Not actual size.*
Paragard is not known to affect ovulation, so patients can start trying to get pregnant the same day it is removed.
