Özet
Objective: Comparison of two different embryo transfer techniques in an IVF program. Design: Prospective, randomized clinical study. Setting: The IVF Research and Practice Center of Istanbul University, Istanbul, Turkey. Subjects: 298 patients undergoing IVF-ET. Interventions: Patients were randomly assigned to undergo ET by different techniques. All patients were transferred with the TDT catheter. The tip of the outer catheter was straight in group 1(n=152) and it was bent to approximate the curvature of the cervical canal in group 2(n=146). Main Outcome Measures: Pregnancy rate and simulate technical difficulty with ET. Results: Pregnancy rate in group 2 was significantly higher than group 1 (27.4% vs. 17.7%). Technical difficulty was similar for both techniques. Conclusions: Bending the tip of the transfer catheter to simulate the curvature of the cervical canal improves the pregnancy rate.
