Intrauterine deposition of calcium on copper-bearing intrauterine contraceptive devices.
Copper-bearing intrauterine contraceptive devices (IUDs) removed after various times in utero were examined by scanning electron microscopy and x-ray microanalysis of the elements present. As time in utero increased these devices became increasingly calcified. This calcification may limit the release of copper from the devices and decrease the specific contraceptive effectiveness of copper over...
متن کاملA novel copper/polydimethiylsiloxane nanocomposite for copper-containing intrauterine contraceptive devices.
In 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. The chemical structures and surface morphologies of the Cu/PDMS composites were ...
متن کاملMenometrorrhagia in magnetic resonance imaging operators with copper intrauterine contraceptive devices (IUDS): a case report.
The paper describes the cases of 3 female health operators with implanted copper IUDs, developing menometrorrhagia some months after an increase of the working time in a Magnetic Resonance Imaging (MRI) Unit (1.5 T), that progressively disappeared when the previous organization, involving discontinuous work shifts at MRI, was re-established. No known factors possibly related to menometrorrhagia...
متن کاملIntrauterine contraceptive devices.
In recent years there has been an upsurge of interest in the intrauterine contraceptive devices (I.U.C.D.) both as a means of controlling the world population explosion and as another contraceptive for use in routine family planning. The characteristic of the intrauterine device method which disti'nguishes it from all other methods of contraception is that its' effectiveness is largely independ...
متن کاملNon-contraceptive Effects of Intrauterine Contraceptive Devices
There is a need for long-acting birth control methods. Copper-bearing intrauterine contraceptive devices do not have systemic side effects and they are appropriate for parous women who have no excess menstrual flow or cramps at baseline and who have low risk for sexually transmitted infections. Levonorgestrel-releasing intrauterine systems release levonorgestrel directly into uterine cavity. Th...
