The Timing of Embryo Transfer Catheter Removal: Should It be Delayed or Done Immediately? A Prospective Randomized Trial

The Timing of Embryo Transfer Catheter Removal: Should It be Delayed or Done Immediately? A Prospective Randomized Trial

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 cathet...

description 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

Methods: A prospective randomized study was designed. ICSI/ET patients &lt;40 years were randomly assigned to either of the group from which catheter was withdrawn immediately within the first 5 s (Group A) or after a 30 s delay (Group B) following ET.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.</description><identifier>ISSN: 0378-7346</identifier><identifier>EISSN: 1423-002X</identifier><identifier>DOI: 10.1159/000460250</identifier><identifier>PMID: 28222446</identifier><language>eng</language><publisher>Basel, Switzerland</publisher><subject>Original Article</subject><ispartof>Gynecologic and obstetric investigation, 2018-01, Vol.83 (1), p.29-34</ispartof><rights>2017 S.
