The TCu380A (GYNET 380 IUD) demonstrates 100% efficacy in long-term users (>5 years). Actinomyces incidence peaked within 3 years and did not increase with extended use, supporting its safety for long-term contraception.

Area of Science:

  • Gynecology
  • Public Health
  • Contraception

Background:

  • Intrauterine devices (IUDs) are a common form of long-acting reversible contraception.
  • The TCu380A IUD is widely used, but data on its efficacy and safety beyond 5 years is crucial.

Purpose of the Study:

  • To evaluate the long-term efficacy of the TCu380A (GYNET 380 IUD) for periods exceeding 5 years.
  • To determine the incidence of Actinomyces colonization in relation to IUD duration and reasons for removal.

Main Methods:

  • Retrospective descriptive study of 370 patients using TCu380A IUDs.
  • Data collected from a Municipal Family Planning Centre in A Coruña, Spain (1988-1997).
  • Analysis focused on users with >5 years of IUD use and Actinomyces incidence.

Main Results:

  • 100% efficacy observed in 271 patients (73.5%) using the TCu380A IUD for over 5 years.
  • Accumulated incidence of Actinomyces was 5.9%, with the highest rates between years 2 and 3.
  • No increased Actinomyces incidence was noted after 5 years of use; 32.3% removed IUDs after 8 years of use.

Conclusions:

  • The TCu380A IUD maintains 100% efficacy for long-term use (>5 years).
  • Actinomyces incidence does not increase with extended TCu380A IUD use beyond 5 years.
  • The device is safe and effective for long-term contraception, with duration of use being a primary removal reason.
