Copper intrauterine contraceptive device event rates following insertion 4 to 8 weeks post partum.

There is a consensus in the literature that intrauterine contraceptive devices (IUDs) should not be inserted within 8 weeks post partum because of reported greater rates of pregnancy, expulsion, and perforation. This greater incidence of event rates was observed in certain clinics that used large plastic IUDs, mainly the loops. In an effort to determine whether the interval from delivery to insertion of a copper-bearing IUD caused altered event rates, an analysis of studies of parous women who were using five different copper-bearing IUDs was undertaken. During the time of these studies, 411 women had an IUD inserted between 4 and 8 weeks post partum, whereas 1,197 women had the IUD inserted more than 8 weeks after a term delivery. At the end of 1 and 2 years of use, there were 4,164 and 6,816 woman months of experience, respectively, in the women with postpartum insertion, and 11,647 and 19,733 woman months of experience with insertion more than 8 weeks post partum. There were no uterine perforations in this experience, and there were no significant differences in the termination rates of any event between the two groups. This retrospective analysis indicates that copper IUDs can be inserted at the time of the routine postpartum examination without concern that the rate of accidental pregnancy, expulsion, or removal for bleeding and/or pain will be increased in comparison with a later insertion.

Five years' experience of intrauterine contraception with the Nova-T and the Copper-T-200.

A randomized study was performed for the comparison of two copper-releasing intrauterine contraceptive devices (IUDs), the Nova-T and the Copper-T-200, simultaneously in Denmark, Finland, and Sweden. Five years' experience demonstrated that Nova-T users had a significantly lower pregnancy rate than Copper-T-200 users. The Pearl index over 5 years was 0.8 for Nova-T users and 2.0 for Copper-T users. The performance and tolerance of the Nova-T were less affected by parity and age than was the performance of the Copper-T. Infections were treated by removal of the device and with antibiotics. The cumulative rate of removals because of infections and suspected infections was below 5 with both devices over 5 years. The copper wire in the Nova-T has a silver core which prevents corrosion-induced fragmentation of the wire. Hence, the effective lifetime of this device is more than 5 years. The results indicate that the Nova-T, which is easy to insert and remove and is associated with a low pregnancy rate and a low medical termination rate, is a real improvement over other IUDs.

Interval iud insertion in parous women: a randomized multicentre comparative trial of the Lippes Loop D, TCu220c and the Copper 7.

A multicentre randomized clinical trial of the TCu220C, Lippes Loop D and Copper 7 was undertaken in nine WHO Collaborating centres for Clinical Research in Human Reproduction. A total of 984, 992 and 994 devices, respectively, were inserted between 1976 and 1978. The subjects were followed for two years. At this time 18,743, 17,013 and 17,927 woman-months experience had been accumulated with each device, respectively. The Lippes Loop consistently failed to perform as well as the TCu220C regardless of age or parity. The TCu220C had statistically significantly lower pregnancy rates at one and two years of use than either of the other two devices as well as lower expulsion rates. The TCu220C had lower removal rates at one and two years than the Lippes Loop and Copper 7. At one and two years the TCu220C had significantly higher continuation rates than the other two devices. It is concluded that the TCu220C is the device of choice amongst the three devices studied.

Experience with Lippes loop and copper-T intrauterine devices in rural Bangladesh.

Experience with IUD use among rural Bangladeshi women within two programmatic efforts demonstrates that the Copper-T IUD suited the needs of younger, lower-parity women better than Lippes Loop. The differential performance by the device was especially marked within the program that offered a broad selection of contraceptive methods and occurred mainly because of lower rates of expulsion and lower rates of discontinuation for bleeding and pain among the Copper-T users. Nevertheless, the easy availability of a wide choice of methods during the second program successfully encouraged dissatisfied IUD discontinuers to try other methods of contraception.

Preliminary report on a postpartum CuT 200 study, Santiago, Chile.

An analysis is presented of a study of the Copper-T 200 (CuT 200) intrauterine device at the Barros Luco Hospital in Santiago, Chile. The devices were inserted in 1142 postpartum patients. The expulsion rate was high, 32.1% at 3 months. Of the 372 women who expelled devices, 349 received a replacement CuT 200. The expulsion rate for these reinsertions was 7.7% at 12 months with a continuation rate of 86.4%.

Concentrations of copper in human secretions and weight of the copper wire during the 4 to 7 years after insertion of a Cu-IUD (intrauterine device).

The useful life span of the two most commonly used copper intrauterine devices (Cu-IUDs) (Gravigard and Cu-T) was investigated in a long-term study up to 90 months after insertion. Minor differences between the two types of devices were found that, however, probably do not contribute to a diverging contraceptive efficacy with time. To be able to ensure maximal contraceptive effect, the authors suggest on the basis of the present data that the time of use not exceed 5 to 6 years.

Clinical experience with Progestasert beyond one year of use.

A total of 254 women were enrolled in the study of the intrauterine progesterone system, Progestasert, and some of the subjects have been followed into the 8th year of use of the device. Clinical experience on 192 women in their 1st year of use of the device was reported in 1977. This follow-up study reports on 110 patients who had at least 2 insertions of the Progestasert for continuous use of 13 months, to a maximum of 8 insertions for continuous use of up to 86 months, for a total of 3808 months. 60% of subjects were nulliparous women who tolerated the device as well as the multiparous. The expulsion rate was low (3.5/100 women-years) noting that 82% of expulsions occurred within 2 months postinsertion or exchange of the device. A total of 7 pregnancies were observed; the pregnancy rate was 2.2/100 women-years. 2 of these 7 pregnancies were ectopic. No uterine or cervical perforations and no serious infections were observed.
