Introduction: This prospective pilot study was done to get preliminary data about a new technique of inflecting endometrial injury in order to improve implantation rate in IVF cases. Patients and methods: 60 patients were en-rolled and randomly distributed into 3 groups. Each group included 20 pa-tients. This study was conducted in the Egyptian consultants for infertility management and IVF center Tanta-Egypt, in the period from January 2015 to March 2016. In group A (study group 1), the 20 patients included in this group underwent endometrial scratching once at day 21 of menstrual cycle in the cycle prior to ET by a 4 mm disposable Karman’s cannula inserted through the cervical os. While in group B (study group 2), the 20 patients underwent the new technique of endometrial Ice bars application for 10 minutes at day 7 of the embryo transfer cycle to inflect the physical trauma required for the change in the endometrial receptivity. In Group C (control group), the 20 patients didn’t receive any extra action rather than the ordinary preparation for embryo transfer. The primary outcome measures of the study were the clinical pregnancy rate and the number of pregnancies that exceeded 14 weeks of gestation. The secondary outcome measures were multiple pregnancy and miscarriage ratios. Results: The results of this pilot study shows a (>14 weeks) pregnancy rate which is equal in the endometrial icing (30% n = 6/20) and endometrial scratching group (30% n = 6\20). The >14 weeks pregnancy rate in both groups is higher than the control group (25% n = 5/20). The small number of patients in the pilot study may explain the difference to be statistically non-significant. The abortion rate was 33.3% (n = 3/9) in the scratching group and 25% (n = 2/8) in the icing group and 16.6% (n = 1/5) in the control group. The multiple pregnancy rate was 16.6% (n = 1/6) in the scratching group and 33.3% (n = 2/6) in the icing group and 20% (n = 1/5) in the control group. Conclusion: Endometrial icing is a new technique of endometrial injury which deserves more studies to test its efficacy in improving embryo implantation and to test its safety.
