Progestin intrauterine devices versus copper intrauterine devices for emergency contraception
Cochrane Database of Systematic Reviews, 2023The copper intrauterine device (Cu-IUD) is a highly effective method of contraception that can also be used for emergency contraception (EC). It is the most effective form of EC, and is more effective than other existing oral regimens also used for EC. The Cu-IUD provides the unique benefit of providing ongoing contraception after it is inserted for EC;

Uterine perforation by copper intrauterine device
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1984Sixteen cases with uterine perforation by a copper intrauterine device (IUD) are presented. In 13 cases the IUD had been inserted within 5 months following delivery, and in 6 cases the insertion had been painful. Missing string was the first sign in most cases. Laparatomy was performed in all cases to remove the IUD.

Endometrial morphology with copper-bearing intrauterine devices
Contraception, 1976Electron microscopic studies of copper (Cu)-T-IUD-bearing endometria using both scanning and transmission electron microscopy (TEM) are extended and CU distribution utilizing an energy dispersive X-ray analyzer is examined. Subjects were 7 39-51 year old patients who had CU-T or CU-7 (220 mm) IUDs inserted 2-54 days prior to hysterect omy.

Copper on Intrauterine Devices Stimulates Leukocyte Exudation
Science, 1972Metallic 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

COPPER INTRAUTERINE CONTRACEPTIVE DEVICES IN ADOLESCENT NULLIPARAE
BJOG: An International Journal of Obstetrics & Gynaecology, 1978SummaryCopper 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.

Menstrual blood loss with copper intrauterine devices
Contraception, 1974Abstract Menstrual blood loss was estimated quantitatively by Halberg & Nilson method for 336 women: 145 normal controls (240 cycles); 91 fitted with Cu-devices (349 collected cycles); 50 fitted with Lippes loops (224 cycles) and 50 on combined steroid contraceptive therapy (236 cycles).

Copper release from copper-T intrauterine devices
Contraception, 1976Abstract 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-

Copper intrauterine contraceptive device and pregnancy rate
Advances in Contraception, 1994Between August 1983 and August 1992, 1995 women aged 20-43 years were fitted with 2736 copper intrauterine contraceptive devices (MLCu250, MLCu375, Nova-T, Gravigard, Anticon). Insertion of the IUD was performed during menstruation by a skilled team of gynecologists. The women were instructed to self-check the IUD tail after each menstrual period.

INTRAUTERINE CONTRACEPTION USING THE COPPER-SEVEN DEVICE
The Lancet, 1972Abstract 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%.

The corrosion chemistry of copper intrauterine devices
Contraception, 1977Abstract A combination of chemical and spectroscopic investigations have proven that the corrosion layer on Copper-7 intrauterine devices (IUDs) consists primarily of copper(I) and copper(II) species with lesser amounts of calcium, iron, and nonmetallic components.
