ABSTRACT
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 <40 years were randomly assigned to either of the group from which catheter was withdrawn immediately within the first 5 s (Group A) or after a 30 s delay (Group B) following ET.RESULTS: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.Palabras clave
