Abstract

Objective The aim of this study was to compare between transvaginal ultrasound (TVS) and transabdominal ultrasound (TAS)-guided embryo transfer (ET) as regards clinical pregnancy rate, patient discomfort, time required for ET, and endometrial visualization during ET. Background ET is an operator, and equipment-dependent procedure. Ultrasound-guided ET allows placing embryos at the desired level within the endometrial cavity. Patients and methods This randomized, prospective trial included 178 infertile couples from Al Shatbi Reproductive Gynecology Unit in Alexandria University Hospital, during the period between June 2016 and May 2018. The patients were divided randomly prior to ET into two equal groups: the first group used TAS guidance for ET and the second group used the TVS guidance for ET. Results The clinical pregnancy rate showed no statistical differences in both groups: 39/89 (43.8%) versus 42/89 (47.2%) (P = 0.652). The mean discomfort intensity during ET was significantly higher in TAS-guided ET group (1.81 ± 1.03 vs. 1.50 ± 0.92) (P = 0.040). The ET took longer time in the transvaginal group. Median 66.0 versus 60.0 s in the transabdominal group (P = 0.125). The optimal endometrial visualization during ET was statistically higher in the transvaginal group: 25 (28.1%) and 45 (50.6%) (P = 0.002). Conclusion There was no significant difference between TVS-guided ET and TAS-guided ET as regards the clinical pregnancy rate. Although the TVS-guided ET took longer time, it allowed less patient discomfort and better endometrial visualization during ET.
