Cu/LDPE Composite IUD
Alternative Name: Nanocomposite Copper (Cu) IUD
Description: A blend of copper and low-density polyethylene (LDPE) nanocomposite material in an IUD shape. The new materials are designed to control the release rate of copper ions, without decreasing the efficacy of the IUD, but reducing the clinical side effects.
