Systematic and standardized hysteroscopic endometrial injury for treatment of recurrent implantation failure

Abstract : Research question: To investigate the effect of hysteroscopic endometrial injury for treatment of recurrent implantation failure (RIF). Design: This prospective and randomized controlled trial included 239 patients who had failed to achieve a clinical pregnancy after the transfer of at least four good-quality embryos in a minimum of three fresh or frozen-thawed embryo transfer cycles and were under the age of 40 years, who were randomized into two groups. The injury group (n = 124) received endometrial injury during their hysteroscopic procedure, whereas the control group (n = 115) did not. Patients who had endometrial pathologies were excluded from the study. Results: There were no statistically significant differences in duration of gonadotrophin use (8.23 versus 8.30 days), total dose of gonadotrophins (2330 versus 2338 IU), number of oocytes (7.03 versus 8.21), number of mature oocytes (5.27 versus 6.02), number of fertilized oocytes (4.19 versus 4.55), number of good-quality embryos (2.07 versus 2.43), number of embryos transferred (1.97 versus 1.93) or endometrial thickness (9.04 versus 9.35 mm) between the injury group and control group, respectively. Clinical pregnancy rates (25.8% versus 15.6%, P = 0.047), live birth rates (21.8% versus 12.2%, P = 0.049) and implantation rates (14.2% versus 8.8%, P = 0.036) were significantly different, favouring the injury group. Conclusion: This study suggests that endometrial injury is beneficial in RIF patients to increase the odds of implantation, clinical pregnancy and live birth.
