Safety of a Contraceptive Copper Vaginal Ring
8 participantsStarted 2026-10-01
Plain-language summary
Many birth control options today come with unwanted side effects or risks. Hormonal methods can affect both mental and physical health, while devices like copper IUDs carry risks such as uterine perforation or infection. This study is testing a new option: a copper vaginal ring (CVR) - a non-hormonal, non-invasive contraceptive that can be self-inserted, similar to a other vaginal rings like NuvaRing or Annovera.
The main goal of this study is to assess whether the copper vaginal ring is safe to use. Researchers will also look at how comfortable and easy it is to use, whether participants follow the instructions, and how much copper accumulates in cervical mucus and vaginal fluid during use.
The study will enroll 8 women of childbearing age. Participants wear the ring continuously for 28 days, inserting it on Day 5 of their menstrual cycle. Over the course of the study, participants will attend 8 in-person clinic visits, which include pelvic exams, vaginal swabs, blood draws, and cervical mucus collection. On the day the ring is removed (Day 28), small tissue samples (biopsies) are taken from the vagina and uterine lining. At the end of the study, participants will complete a short survey about their experience with the ring.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
