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%.

Background T-shaped intrauterine devices (IUDs) with a copper surface area of 380 mm2 and copper bands on the transverse arms are the most effective types of copper-containing IUDs. A small-sized ‘gold standard’ IUD is available but there has been little

Chemical Reactions of the Copper Intrauterine Device
Fertility and Sterility, 1972This study investigated the reactions of metallic copper with various biologic substrates to account for the loss of metallic copper in the IUD. Purified copper foil of .005 cm thickness was cut into strips and placed in solutions of the substrates then incubated at 37 degrees C.
