Abstract

Introduction: Successful implantation during assissted reproductive technique
cycles depend on many factors including embryonic and uterine variables. The aim of
this study was to investigate the difference between embryonic and endometrial
ultrasonographic parameters in patients who had undergone In Vitro Fertilization
(IVF) and Intracytoplasmic (ICSI) in successful and failed cycles.
Methods: In this descriptive study 108 patients aged<38 with basal serum FSH
level<12 and no more than two failed attempts of ART cycles, whose uterin were
confirmed by ultrasound to be morphologically normal, were studied. Ultrasound
evaluation was performed by a single expert on the day of embryo transfer.
Ultrasonographic parameters of endometrium and embryonic variables were analyzed
based on the occurrence of pregnancy.
Results: 33.3% of patients conceived. No significant difference was found between
pregnant and non-pregnant group regarding demographic, hormonal and cycle
characteristics and ultrasonographic parameters. On the contrary, embryonic factors
differed significantly between the two groups.
Conclusion: While embryonic factors significantly influence successful
implantation, there is no relationship between ultrasonographic parameters of
endometrium on the day of embryo and implantation.
