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 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...
متن کاملOPINION Current state of intrauterine contraceptive devices
Background: Intrauterine contraceptive device (IUCD) is the most commonly used method of contraception in many countries. Despite the availability of many generations of IUDs with variable shapes and configurations, side effects and complications are frequent. We hypothesize that a modified IUD design with a fundal seeking effect will nullify the side effects and the complications of the curren...
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 ...
