The GyneFix (Gyne-Fix) intrauterine device (IUD) shows low expulsion and high efficacy. This frameless, flexible IUD implantation technology is effective for various insertion timings, even in nulliparous women.

Area of Science:

  • Reproductive Medicine
  • Medical Device Technology

Background:

  • Intrauterine device (IUD) expulsion is a significant clinical challenge.
  • Implantation technology aims to improve IUD retention and efficacy.
  • The GyneFix (Gyne-Fix) IUD is a frameless, flexible device designed for secure fixation.

Purpose of the Study:

  • To evaluate the efficacy and safety of the GyneFix IUD with an improved inserter for interval insertion.
  • To assess expulsion, pregnancy, and removal rates in a large cohort of women, including nulliparous individuals.

Main Methods:

  • An ongoing multicenter study involving 820 women undergoing interval insertion of the GyneFix IUD.
  • Observation period up to 3 years, with a total experience of approximately 14,000 woman-months.
  • Specific analysis of outcomes in 213 nulligravid/nulliparous women.

Main Results:

  • Cumulative expulsion rate of 0.6 per 100 woman-years at 3 years.
  • No significant difference in expulsion rates between nulliparous and parous women.
  • Cumulative pregnancy rate of 0.6 and cumulative medical removal rate of 3.2 per 100 woman-years at 3 years.

Conclusions:

  • The GyneFix IUD's design (fixed, frameless, flexible) contributes to low expulsion, high efficacy, and high acceptability.
  • The implantation technology, particularly with the improved inserter, facilitates easy insertion and optimal anchoring.
  • The GyneFix IUD is a highly effective and well-tolerated contraceptive option across diverse patient populations.
