| Popis: | Objective: The purpose of this study was to investigate the possible impact of follicular flushing on the number of oocytes retrieved and oocytes in metaphase II in patients with poor ovarian response (POR) compared to direct aspiration. Methods: This prospective, comparative, randomized single center study included 208 punctures of patients with POR, submitted to assisted reproduction technology (ART) treatments. Two groups were compared; one in which double lumen needles were used (Wallace DNS1733) for follicular flushing (n=105), and one in which single lumen needles were used (Wallace ONS1733) for direct aspiration (n=103), upon the observation of ≤ 5 follicles between 15-17 mm, ≤ 4 follicles with sizes greater than 18 mm on hCG day, and ≤ 7 recovered oocytes. Results: There were no differences in age (39.07±3.88 vs. 38.11±3.43); weight (61.73±17.53 vs. 65.96±15.44); AMH (0.63±0.59 vs. 0.94±0.97); stimulation days (9.57±1.87 vs. 10.29±2.82); estradiol levels (788.94±670.82 vs. 940.16±694.69); progesterone (617.29±319.76 vs. 561.18±486.78); or number of follicles with sizes ≥18 mm (1.84±0.95 vs. 2.07±1.09). Although gonadotropin totals (1678.28±798.52 vs. 2080.45±852.36; p=0.0008), number of aspirated oocytes (3.00±2.11 vs. 3.69±2.20; p=0.02), and number of metaphase II oocytes (2.20±1.64 vs. 2.99±1.88; p=0.02) were significantly different, oocyte / follicle ratio ≥15 mm (0.93 vs. 0.98) and metaphase II oocytes / follicles ≥15 mm (0.68 vs. 0.79) were similar in both groups. The failure to capture was 16% vs. 9.8%. Conclusions: Considering that there was no difference in the oocyte per follicle ratio, follicular flushing did not increase the number of oocytes recovered from poor responders. |
