This is a study evaluating 3 non-medicated silicone vaginal rings. The primary aim of this study is to find out which ring size women like best and if male partners prefer one ring size over another. We want to know if the size of the ring makes a difference in how easy or difficult it is for women to use the ring correctly.


Each couple will use each of the 3 non-medicated silicone vaginal rings in 3 different sizes for 30 days per vaginal ring. After enrollment, women will attend 3 additional in-clinic visits and men will attend 3 additional remote (virtual) visits. Women and men will respond to questionnaires before and after each ring, and at the end of the study.

  • 5 study visits over 6 months
  • Questionnaires and an interview
  • Physical exam and STI screening tests
Compensation: Female participants can receive up to $515 and males can receive up to $275 for participation.
