Does Placement of the Catheter Guide Through the Cervical Canal Influence the Embryo Transfer Outcome?

Abstract

Aim: Our aim was to find out whether placement of the embryo transfer catheter guide through the cervical canal at the time of embryo expulsion influences pregnancy rates. Material and Method: We retrospectively com-pared in vitro fertilization (IVF) outcomes related to the placement of the em-bryo transfer catheter guide through the cervix. Subjects were divided into two groups: embryo transfers (ET) performed with the inner catheter alone through the cervical canal (n=55, Group 1) and transfers performed with the double catheter set through the cervix (n=58, Group 2). Results: A total of 113 ETs were carried out in women undergoing IVF treatment. Although the preg-nancy ratio seemed to be higher among the transfers carried out with the inner catheter alone inserted through the cervix, no statistically significance for this was detected (odds ratio: 1.644, 95% confidence bound, p>0.05). Discussion: Placement of the catheter guide through the cervical canal at the time of embryo expulsion may not have any effect on the IVF-ET outcome. © Journal of Clinical and Analytical Medicine.
