FeRTILE Study | Fertility, Reproductive Outcomes & Time to Conception – Impact of Long-term IUD Exposure

The FeRTILE study is being done to learn whether long-term use of an intrauterine device (IUD) affects how long it takes to become pregnant. By taking part, participants may help researchers learn more about fertility and birth outcomes after IUD use.

You may be eligible if you:

  • Are between 25–37 years old 
  • Are trying to conceive 
  • Recently discontinued an IUD or another form of contraception within the past 6 months 
  • Have never been pregnant 
  • Live in the United States 

Participants will complete a baseline questionnaire and short follow-up surveys every 3 months for 1 year. Compensation will be provided for completed surveys.
