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.

Menstrual blood loss with copper intrauterine devices

Contraception, 1974
Abstract 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, 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-

Copper intrauterine contraceptive device and pregnancy rate

Advances in Contraception, 1994
Between 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, 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%.

The corrosion chemistry of copper intrauterine devices

Contraception, 1977
Abstract 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.

Chemical Reactions of the Copper Intrauterine Device

Fertility and Sterility, 1972
This 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.

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.

Complications among adolescents using copper intrauterine contraceptive devices

International Journal of Gynecology & Obstetrics, 2011
To evaluate the rate and pattern of complications associated with use of the Copper T 380A intrauterine device (IUD) among adolescents.A prospective comparative study of women eligible for IUD insertion who attended the family planning clinic of Sohag University Hospital, Egypt, between July 1, 2008 and December 31, 2010.

Intrauterine device and maternal copper metabolism during lactation☆

Contraception, 2001
The effects of intrauterine device (IUD) on maternal copper (Cu) metabolism during breastfeeding was studied in 95 volunteer mothers who chose to use non-hormonal contraceptive methods. They were divided into two groups that were inserted with the IUD-Cu 380A (n = 33), IUD-Cu 200B (n = 29), and a third group that did not use any IUDs served as control (
