Plain-language summary
A PubMed search of "thrombophilia" and "infertility" yields only 98 articles, the majority found in foreign medical journals and subspecialty journals with narrow readerships. Outside of Assisted Reproduction Clinics at academic medical centers, health care providers have limited awareness of the literature supporting thrombophilia evaluation and treatment in patients with recurrent pregnancy loss. As a result, women may suffer through years of repeated miscarriages before a thrombophilia evaluation is performed. By the time thrombophilia has been diagnosed as the cause of recurrent pregnancy loss, couples have often exhausted their personal savings on costly assisted reproductive therapies and present frustrated and psychologically exhausted.
In this study, we will evaluate the frequency of thrombophilia as a cause of recurrent pregnancy loss and provide insights into our patient care experience at BWH.

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?

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?
