INTRAUTERINE CONTRACEPTION USING THE COPPER-SEVEN DEVICE

The Lancet, 1972
Abstract A preliminary study of 342 women over 1196·5 women-months of use of the copper-seven device is described; 32·2% were nulliparous, the rest were multiparous. Insertion was easy in 85%, there were minor problems in 9%, and difficulties in the remaining 6%.

COPPER INTRAUTERINE CONTRACEPTIVE DEVICES IN ADOLESCENT NULLIPARAE

BJOG: An International Journal of Obstetrics & Gynaecology, 1978
SummaryCopper intrauterine contraceptive devices (IUCDs) were used in 243 young nulligravidae attending a gynaecological clinic for schoolgirls in Uppsala between March 1973 and June 1975; 226 of these girls (93 per cent) were seen again during December 1975 making a total of 3138 months of observation.

Copper on Intrauterine Devices Stimulates Leukocyte Exudation

Science, 1972
Metallic copper in the uterine or abdominal cavities of rats or monkeys stimulates an impressive local exudation of polymorphonuclear leukocytes. This cellular response to copper persists for at least 7 months, without significant local tissue damage or detectable systemic effects on the test animal. This finding provides a possible explanation for the

Reactive molecules and microorganisms and copper intrauterine devices

International Journal of Gynecology & Obstetrics, 2005
Copper in the intrauterine device (IUD) has been shown to have bactericidal activity in addition to enhancing contraceptive activity. However the exact mechanism of antimicrobial action of copper IUD is not known. The increase in the number of polymorphonuclear leukocytes in the endometrium following IUD insertion has been documented.

Copper release from copper-T intrauterine devices

Contraception, 1976
Abstract In this investigation of the copper loss in utero from the Copper-T, the release rate was estimated by iodometric titration and the corrosion was microscopically examined in ground plastic casts. The release rate was determined in 28 preweighed Copper-Ts with a surface area of 100–400 mm 2 during the first month, and in 60 Copper-T-200s (TCu-

Clinical Experience with the Copper 7 Intrauterine Device

Fertility and Sterility, 1978
This 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.

Copper intrauterine devices in the management of secondary amenorrhea

International Journal of Gynecology & Obstetrics, 2006
Secondary amenorrhea has always been a challenge for the gynecologist. The incidence is reported to be between 1.4% and 3% in the general population [1,2], and its causes can be hypothalamic (62%), pituitary (15%), ovarian (12%), or anatomical (7%). Intrauterine devices have been used to treat Asherman syndrome. Lately, copper intrauterine devices have

A statistical study of the copper T and copper 7 intrauterine devices

Contraception, 1976
The performance of the Copper T and Copper 7 IUDs over a 3-year period was assessed. A total of 581 women received the Copper T and 297 received the Copper 7. Net cumulative event rates were determined at 12 24 and 36 months/100 women. Both groups were similar with respect to age and parity.

Serum Copper in Long-Term Users of Copper Intrauterine Devices

Fertility and Sterility, 1980
A 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 coppergold or copperplatinum intrauterine device

Journal of Biomedical Materials Research, 1982
AbstractIt 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 ...
