    Area of Science:

    • Reproductive Health
    • Medical Devices
    • Contraception

    Background:

    • Intrauterine devices (IUDs) are a common form of reversible contraception.
    • Assessing the long-term safety and effectiveness of specific IUD models is crucial for clinical practice.

    Purpose of the Study:

    • To evaluate the six-year contraceptive effectiveness and safety of the Cu-T-200 intrauterine device.
    • To analyze event rates associated with the Cu-T-200 over an extended duration of use.

    Main Methods:

    • A prospective study involving 833 first insertions of the Cu-T-200.
    • Data collection on contraceptive events including pregnancy, expulsion, and removal for pain, bleeding, or medical reasons.

    Main Results:

    • No increase in event rates (pregnancy, expulsion, pain/bleeding removal, medical removal) was observed with longer duration of Cu-T-200 use.
    • The cumulative event rates remained low throughout the six-year study period.

    Conclusions:

    • The Cu-T-200 intrauterine device is a safe and effective contraceptive method for up to six years.
    • Sustained contraceptive performance suggests suitability for long-term family planning needs.
