Objective: The aim of this trial was to determine whether endometrial scratch-suction caused by insertion tube of (IUCD) with suction improved the probability of pregnancy in the subsequent IVF cycle in patients who had previous failed IVF outcome by removing small polyps and any hazardous materials. Design: Observational prospective cohort experimental study. Setting: Zagazig University Hospital, Obstetrics and Gynecology department. From period between September 2011 till September 2012. Population: 30 patients with previous failed IVF despite transfer of goodquality embryos were allocated to endometrial scratch-suction in the same the cycle of embryo transfer. Methods: From day 5 to day 7 of same ICSI cycle, the patients in study underwent endometrial scratch-suction technique. After preparation of insertion tube of (IUCD) and infant feeding tube 8 F, moving the insertion tube of IUCD from below upwards with scratching anterior uterine wall, then posterior, then left lateral uterine wall, then right lateral uterine wall, then fundus, all these steps are associated with suction by attaching proximal end of infant feeding tube 8 F to suction apparatus. Main Outcome Measures: Implantation and clinical pregnancy rates. Results: The implantation occurred in 24/30 (80%). The clinical pregnancy occurred in 20/30 patients (66.66%). 12/30 patients (40%) during scratch-suction technique had small fleshy masses obstructing suction tube which were small endometrial polyps. Conclusions: Endometrial scratch-suction improves clinical pregnancy and implantation rates in the same IVF-ET cycle in patients with previous unsuccessful IVF cycles.
