Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This proposed research is a single center, prospective, single-blinded, randomized controlled trial, designed to evaluate IVF pregnancy outcomes following endometrial injury in 254 patients with implantation failure. Patients will be identified during their work-up and treatment at Shady Grove Fertility Reproductive Science Center. Only Shady Grove patients are eligible for the study. The investigators hypothesize in patients with one or more previous failed day 5 blastocyst transfers, injury to the endometrium via endometrial biopsy will improve clinical pregnancy outcomes compared to controls.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Despite advances in assisted reproductive technologies; implantation failure in patients undergoing in-vitro fertilization (IVF) is frequent. Unfortunately, few treatments exist except for the use of a gestational carrier. There have been a number of recent clinical studies demonstrating that local injury to the endometrium results in improved clinical pregnancy outcomes for patients with a history of implantation failure. However, not all studies have shown a beneficial effect, and those demonstrating benefit have been limited by small sample sizes, and considerable heterogeneity in the procedures and populations evaluated. A recent meta-analysis synthesized the available data concluded that a large, prospective, well-designed randomized trial is desperately needed to definitively assess this new possible treatment. If these preliminary findings from previous trials are confirmed, this practice could be applied in the clinical setting to help patients suffering from repeated implantation failures.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Endometrial Biopsy

Subjects will have a vaginal speculum placed and visualization of the cervix will be obtained. The cervix will be cleaned with betadine (or hibiclens for those with an iodine allergy). Those randomized to the treatment arm (endometrial biopsy) will have an endometrial pipelle (Endocell, Wallach, Orange, Connecticut) inserted gently through the cervix into the uterus. Two passes will be performed with the pipelle catheter. For each pass the catheter will be rotated and scraped 4 times, once in each quadrant.

Group Type EXPERIMENTAL

Endometrial Biopsy

Intervention Type PROCEDURE

Control

Those randomized to the control group will have a small cotton swab placed gently into the cervix. No tissue will be obtained with this method. The randomization to a placebo control is necessary to prove that any positive effects seen are due to the biopsy and not just random chance.
