Progestin intrauterine devices versus copper intrauterine devices for emergency contraception
Cochrane Database of Systematic Reviews, 2023The copper intrauterine device (Cu-IUD) is a highly effective method of contraception that can also be used for emergency contraception (EC). It is the most effective form of EC, and is more effective than other existing oral regimens also used for EC. The Cu-IUD provides the unique benefit of providing ongoing contraception after it is inserted for EC;

The corrosion chemistry of copper intrauterine devices
Contraception, 1977Abstract A combination of chemical and spectroscopic investigations have proven that the corrosion layer on Copper-7 intrauterine devices (IUDs) consists primarily of copper(I) and copper(II) species with lesser amounts of calcium, iron, and nonmetallic components.

Uterine perforation by copper intrauterine device
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1984Sixteen cases with uterine perforation by a copper intrauterine device (IUD) are presented. In 13 cases the IUD had been inserted within 5 months following delivery, and in 6 cases the insertion had been painful. Missing string was the first sign in most cases. Laparatomy was performed in all cases to remove the IUD.

Endometrial morphology with copper-bearing intrauterine devices
Contraception, 1976Electron microscopic studies of copper (Cu)-T-IUD-bearing endometria using both scanning and transmission electron microscopy (TEM) are extended and CU distribution utilizing an energy dispersive X-ray analyzer is examined. Subjects were 7 39-51 year old patients who had CU-T or CU-7 (220 mm) IUDs inserted 2-54 days prior to hysterect omy.

Copper intrauterine contraceptive device and pregnancy rate
Advances in Contraception, 1994Between August 1983 and August 1992, 1995 women aged 20-43 years were fitted with 2736 copper intrauterine contraceptive devices (MLCu250, MLCu375, Nova-T, Gravigard, Anticon). Insertion of the IUD was performed during menstruation by a skilled team of gynecologists. The women were instructed to self-check the IUD tail after each menstrual period.

Chemical Reactions of the Copper Intrauterine Device
Fertility and Sterility, 1972This study investigated the reactions of metallic copper with various biologic substrates to account for the loss of metallic copper in the IUD. Purified copper foil of .005 cm thickness was cut into strips and placed in solutions of the substrates then incubated at 37 degrees C.
