Serum Copper in Long-Term Users of Copper Intrauterine Devices
Fertility and Sterility, 1980A study was undertaken to determine whether long-term use of a copper intrauterine device (IUD) was associated with any alteration in the serum copper levels and thereby whether absorption of copper from the device in utero could result in copper toxicity.

Corrosion of a new coppergold or copperplatinum intrauterine device
Journal of Biomedical Materials Research, 1982AbstractIt has been shown previously that supplementing plastic intrauterine devices (IUDs) with copper wire enhances the antifertility effect of the device. The use of copper intrauterine contraceptive devices, however, is currently limited to two to three years, mainly because of wire fragmentation, which was observed as early as after eight months ...

The mechanism of action of the copper intrauterine device.
Fertility and sterility, 1976The effects of copper ions on the binding of steroids to receptors revealed that the inhibitory effect of Cu++ was apparent at 10(-6)M, ANd the binding capacities decreased to 10% at 10(-2)M Cu++. The kinetic study demonstrated that Cu++ was a competitive inhibitor of steroid hormone-receptor binding (Ki divided by 2.7 X 10(-5)M to estrogen receptor ...

Hair copper in intrauterine copper device users.
IRCS journal of medical science, 1984The antifertility effect of copper-bearing IUDs is based on continuous release of copper, which is a result of the reaction between the metal and the uterine secretions. Released cupric ions collect in the endometrium and in the uterine fluid but significant accumulation has not been found in the bloodstream or elsewhere. Following Laker's suggestion

Copper intrauterine contraceptive devices and serum essential metals
Advances in Contraception, 1988Serum levels of the essential metals, iron (Fe), copper (Cu), magnesium (Mg), zinc (Zn), and calcium (Ca), were determined by atomic absorption spectrophotometry in one hundred and twenty randomly selected adult Nigerian female volunteers fitted with copper T or Delta T intrauterine contraceptive devices (IUDs) for a period of 3-18 months, and their ...

Secondary cervical perforation by the Copper-T intrauterine device
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1979Five cases of cervical perforation have been observed in women with a Copper-T IUCD, over a period of 5 yr. In all cases, the distal end of the stem (vertical limb) of the T had perforated through the cervical wall into one of the fornices of the vagina. Only 2 cases had symptoms leading to the discovery of the device, while the other 3 were discovered
