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.

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.

The Copper Intrauterine Device and Its Mode of Action
New England Journal of Medicine, 1975Copper bearing intrauterine devices have become the most reputable effective and safe IUDs available. The reaction between the copper and the body prevents fertilization. An infiltration of polymorphonuclear leukocytes occur in the uterine lumen as a result of the IUD. The daily released copper is equivalent to 1% of the copper taken orally by day.

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.

URTICARIA SECONDARY TO A COPPER INTRAUTERINE DEVICE
International Journal of Dermatology, 1976ABSTRACT: A 24‐year‐old woman developed an acute urticarial reaction secondary to a copper intrauterine contraceptive device. Allergy to copper was proven by scratch tests. The condition cleared with removal of the IUD.
