Copper IUD Comparison Study

Are you looking for a non-hormonal birth control?

Copper IUD Comparison Study Image #16899

OHSU Women's Health Research Unit is conducting a study to test how the investigational non-hormonal copper IUD compares to the FDA approved ParaGard in patient satisfaction and preventing pregnancy. 

The investigational IUD is a smaller version of the ParaGard. Previous research has suggested that smaller copper IUDs may cause fewer side effects for women with smaller uterine cavities. Currently the ParaGard is the only FDA approved non-hormonal IUD in the United States. This research aims to increase options for women who are seeking non-hormonal birth control. 

You may be eligible for this study if you are: 

  • Generally heathly
  • A woman between 16-40 years of age
  • Having regular menstrual cycles
  • At risk for pregnancy

Qualified participants will be compensated up to $565 for time and travel. Study participation will last approximately 37 months and includes receiving a Copper IUD, 7-8 in person visits, 4 phone call check-ins, and completing a daily diary.
