The ParaGard® T 380A intrauterine copper contraceptive (IUC) is a T-shaped device, measuring 32 mm horizontally and 36 mm vertically with a 3-mm–diameter bulb at the tip of the vertical stem.1
A monofilament polyethylene thread is tied through the tip, resulting in 2 white threads, each at least 10.5 cm in length, to aid in detection and removal of the device. The T-frame is made of polyethylene, with barium sulfate to aid in detecting the device under x-ray. ParaGard® contains approximately 176 mg of copper wire coiled along the vertical stem and a
68.7-mg copper collar on each side of the horizontal arm. The total exposed copper surface area is 380 mm2 ± 23 mm2.1
Hormone-free ParaGard® is believed to work primarily by preventing sperm from reaching and fertilizing the egg. It may also prevent the egg from attaching to the uterus. The contraceptive effectiveness of ParaGard® is enhanced by the continuous release of copper into the uterine cavity. ParaGard® is indicated for intrauterine contraception for 2, 5, even up to 10 years, but patients may have it removed any time before then, depending on their needs and family planning goals.1
