Abstract
Purpose: To determine whether the use of ultrasound (US) to guide embryo transfer (ET) in a population previously defined as likely to have easy transfer would change the implantation and pregnancy rates in an ICSI program.
Methods: A total of 100 patients identified as likely to have easy transfer after mock transfer were divided into two groups: Group I, US-guided ET (N=50) and Group II, ET without the aid of US (N=50).
Results: Implantation and pregnancy rates were similar (p=0.51, p=0.29) for Group I (19.6%, 42%) and Group II (16.3%, 30%), as also was the abortion rate (p=0.55) (Group I: 1/21; Group II: 2/15).
Conclusion: As long as previous mock transfers are routinely performed during a cycle preceding assisted reproduction and the clinician considers transfer to be easy, ultrasound does not benefit the process of embryo transfer.
