Background/Aims: Data on the timing of catheter removal technique following embryo transfer (ET) are quite limited. We aimed to compare the reproductive outcomes of intracytoplasmic sperm injection (ICSI)/ET cycles in which the transfer catheter was removed immediately with those in which the catheter was removed after a delay period and hereby to evaluate the impact that the time interval before removal of the catheter following embryo deposit may have on the fertility outcomes. Methods: A prospective randomized study was designed. ICSI/ET patients Results: Groups A and B consisted of 147 and 148 patients, respectively. Patient demographics and stimulation characteristics were comparable between the groups. Pregnancy rate was 32.2% (95 of 295) and clinical pregnancy rate was 28.8% (85 of 295), whereas ongoing pregnancy was 24.4% (72 of 295) and implantation rate was 29.6% (100 of 338). The comparison of reproductive outcomes revealed no significant differences in pregnancy (p = 0.933), clinical pregnancy (p = 0.673), ongoing pregnancy (p = 0.590), multiple pregnancy (p = 0.801), and implantation rates (p = 0.979) between the groups. Conclusion: No significant difference was observed in the reproductive outcomes between the groups; thus, there appears no requirement to delay the withdrawal of the catheter to improve the outcomes in ICSI cycles.
