Summary
The new Copper-Fix intrauterine device (IUD) shows excellent uterine retention and low removal rates for bleeding or pain. This innovative IUD offers a safe and effective long-term contraception option.
Area of Science:
- Reproductive Medicine
- Medical Devices
- Contraception
Background:
- Intrauterine devices (IUDs) are common contraceptives.
- Bleeding and pain are frequent reasons for IUD removal.
- Current IUD technology has limitations in addressing these issues.
Purpose of the Study:
- To evaluate the safety and efficacy of the Copper-Fix (Cu-Fix) IUD.
- To assess the performance of a novel IUD design aimed at reducing common side effects.
Main Methods:
- The Copper-Fix 390 was inserted in 382 women.
- Data collected over 4851 woman-months up to 18 months post-insertion.
- Key outcomes included expulsion, removal for bleeding/pain, pregnancy, and continuation rates.
Main Results:
- Excellent uterine retention with a low expulsion rate of 0.6% at 18 months.
- Low removal rate for bleeding/pain at 3.1% at 18 months.
- Pregnancy rate was 0.3% with a high continuation rate of 87.6%.
Conclusions:
- The Copper-Fix IUD demonstrates superior retention and reduced side effects compared to traditional IUDs.
- Its innovative design, featuring no frame and an anchoring system, overcomes common IUD-related problems.
- The device is safe and effective for long-term contraception, irrespective of patient age or gravidity.
