Back ground In the last two decades, assisted reproductive technology procedures for culturing and transferring embryos have been continually improved, but the clinical pregnancy rate has not improved substantially over the last 10 years. The most important cause for implantation failure is embryo quality or uterine receptivity, but remains unexplained in many cases. About 75% of conceptus are lost before or at the time of implantation. Aim This work aims to assess the effect of endometrial scratch (ES) using a Pipelle catheter on the outcome of intracytoplasmic sperm injection (ICSI) in patients with recurrent implantation failure. Patients and methods The current study included 130 patients who were divided into two equal groups of 65 patients each. In the scratch group, endometrial local scratch using a Pipelle biopsy catheter on the mid luteal phase of spontaneous menstrual cycle before the ICSI procedure was performed, whereas the control group did not undergo ES. ICSI failure was recorded two or more times in each group. Results In the current study, there were no statistically significant differences between the two groups in age, gravidity and parity, type, duration of infertility, and the number of previous ICSI trials. However, the BMI was higher in the control group. In the current study, there were no statistically significant differences between the two groups in basal hormonal profile follicle-stimulating hormone, luteinizing hormone, thyroid-stimulating hormone, prolactin, estradiol, and anti-Müllerian hormone. In this study, there was highly significant increase in the pregnancy rate in the scratch group than the nonscratch group. The number of pregnant cases in the scratch group was 36 (55.4%), whereas in the control group, it was 21 (32.3%), with a highly significant P value of 0.008. In this study, there was no statistically significant difference between positive and negative pregnancy in the basal hormonal profile, except anti-Müllerian hormone and follicle-stimulating hormone levels, P values of 0.040 and 0.000. Conclusion ES in the cycle before the ICSI cycle improved the chemical and clinical pregnancy rates compared with ICSI performed without ES in cases of recurrent implantation failure. It seems that increasing pregnancy rates could be because of the local inflammatory reaction elicited by the endometrial sampling procedure.
