Abstract
Background: Infertility is an important problem that affects many couples worldwide.
Assisted reproductive technology (ART) helps infertile couples to have offspring. One
of the critical parts of ART is embryo transfer (ET).
Objective: To compare the effect of transvaginal and transabdominal ultrasonographyguided
ET on ART outcomes.
Materials and Methods: In this randomized clinical trial study, 90 women who were
candidates for in vitro fertilization (IVF) referred to Mahdiyeh hospital of Tehran, Iran
during the yr 2020 were randomly divided into two groups (n = 45/each) of transvaginal
and transabdominal ultrasonography-guided ET. The embryos were transferred two-three
days after oocyte retrieval. The patient pain, duration and difficulty of the
procedure, three-dimensional vision quality and successful pregnancy rate were
measured.
Results: In this study, 63.2% of the 45 women who underwent IVF under the
guidance of the transvaginal guidance and 36.8% of the 45 women who underwent
IVF under the transabdominal guidance had a successful pregnancy, which was not
significantly different (p = 0.19). Also, based on other results there was no difference
between the two groups in terms of patient pain (p = 0.53), duration (p ≥ 0.50),
difficulty of procedures (p ≥ 0.50) and ultrasonography vision; however, the three-dimensional
vision quality in the transvaginal ultrasonography was better than that in
the transabdominal ultrasonography (p < 0.01).
Conclusion: Overall, the ART outcomes in the transvaginal and transabdominal
ultrasonography-guided ET were similar, so we suggest that physicians evaluate the
patient’s situation, the hospital equipment, and their ability before selecting the type of
ultrasonography.
