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

Clinical Experience with the Copper 7 Intrauterine Device
Fertility and Sterility, 1978This paper reports further observations on our previous study of 203 Copper 7 intrauterine insertions performed in 199 women. There have now been accumulated 3799 woman-months of use. At least a 2-year period of observation has been attained from first insertion until these data were analyzed.

Active oxygen species in copper intrauterine device users
Contraception, 1993The mechanism of copper intrauterine device (Cu IUD) in limiting intrauterine infections is poorly understood. Copper ions may enhance the release of reactive oxygen species which are deleterious to the microbes. The present study compares the oxidative responses of adherent cell population of uterus prior to Cu-T insertion and at different post ...

Copper Particles From Intrauterine Contraceptive Device
Archives of Dermatology, 1974To the Editor.— Recently, in the process of evaluating the inflammatory response to different surface textures of plastic, our attention was drawn to the article by Dr. Barranco on eczematous dermatitis caused by internal exposure to copper published in theArchives(106:386, 1972). The results of our studies confirmed his observation that small amounts

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 ...

AbstractIn this article, a novel composite of copper (Cu) nanoparticles and polydimethiylsiloxane (PDMS) has been prepared and investigated for the potential application in Cu‐containing intrauterine device. The Cu/PDMS composite with various mass fraction of Cu nanoparticles was fabricated via the hot vulcanizing process.

Uterine Copper Distribution in Monkeys Implanted with Copper-Carrying Intrauterine Devices
Fertility and Sterility, 1975Chemical and histochemical analyses were carried out on uteri of four monkeys in which plastic IUDs or Cu-IUDs had been implanted for 36 to 43 days. The mean uterine copper content of the plastic-treated animals was 1.1 mug/gm (mean of two), while this value for the Cu-IUD treated monkeys was 1.7 mug/gm.
