Experience with the Ypsilon (Soichet) intrauterine device.

S Yarkoni, E Sadovsky

    Israel Journal of Medical Sciences
    |February 1, 1978
    PubMed
    Summary

    The Ypsilon intrauterine device (IUD) showed a 6.4% pregnancy rate and 3.8% expulsion rate in a study. While effective in preventing perforations, its high pregnancy rate warrants consideration for clinical use.

    Area of Science:

    • Reproductive Health
    • Medical Devices
    • Contraception

    Background:

    • Intrauterine devices (IUDs) are a common form of reversible contraception.
    • Assessing the safety and efficacy of novel IUD designs is crucial for reproductive health.
    • The Ypsilon IUD is a specific model composed of stainless steel and silicone rubber.

    Purpose of the Study:

    • To evaluate the clinical performance of the Ypsilon intrauterine device (IUD).
    • To determine the pregnancy, expulsion, and medical removal rates associated with Ypsilon IUD use.
    • To assess the safety profile of the Ypsilon IUD, including complications like perforations.

    Main Methods:

    • A prospective study involving 209 women utilizing the Ypsilon IUD.
    • Data collection over 3,169 woman-months of use.
    • Calculation of net cumulative rates for pregnancy, expulsion, and medical removal at 12 months.

    Main Results:

    • A 12-month cumulative pregnancy rate of 6.4% was observed.
    • The cumulative expulsion rate was 3.8%.
    • A medical removal rate of 9.0% due to side effects was recorded. No perforations or tubal pregnancies occurred.

    Conclusions:

    • The Ypsilon IUD demonstrates a low rate of serious complications such as perforations and tubal pregnancies.
    • The device exhibits a relatively low medical removal rate, suggesting good tolerability.
    • However, the observed pregnancy rate is considered high, impacting its overall suitability for widespread clinical use.
