Plain-language summary
Repeated implantation failure (RIF) is determined when failure of implantation occurred during at least three consecutive IVF attempts while at least one high-grade embryo was transferred in each cycle. Several methods have been suggested to improve the implantation rate in RIF patients. One of the most promising methods is local injury to the endometrium. It has been reported that the rates of implantation, clinical pregnancy, and live birth reach more than double in RIF patients with local endometrial injury than patients without it. The population of this study included all infertile couples attending the Royan Institute, who have at least three consecutive cycles of ART failure. Also this study is phase 3 randomized clinical trial. Based on the average menstrual cycle 30-28 days, endometrial and blood samples were collected from two groups of patients on day 21 of luteal phase of their spontaneous menstrual cycle. The intervention, but not the control group underwent prior biopsy treatment in follicular phase on days 8 or/and 11 to 13 of that same cycle but in these days blood sample in both groups were collected. To investigate the impact of local endometrial injury in increasing the rate of pregnancy in ART - treated RIF patients, the investigators will examine the changes of immunological factors involved in the implantation including some cytokines, growth factors ( in serum and endometrial biopsies) and the expression of TLRs and HOX genes ( in endometrial biopsies) obtained from both groups.

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?
