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.

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.

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.

A statistical study of the copper T and copper 7 intrauterine devices
Contraception, 1976The 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.

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

Cervical perforation by the copper-T intrauterine device
Contraception, 1973Abstract Four cases of cervical perforation have been observed in a series of 1,220 insertions of the copper-bearing intrauterine device CuT-200. In all four cases, the distal end of the stem (vertical limb) of the T had perforated downward through the cervical wall into the rectovaginal septum (1 case), fornix posterior (2), or anterior (1).

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 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.
