Comparison of Ultrasonographic Parameters of Endometrium and Embryonic Variables in Successful and Unsuccessful Assisted Reproductive Techniques

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. 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. 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. While embryonic factors significantly influence successful implantation, there is no relationship between ultrasonographic parameters of endometrium on the day of embryo and implantation.
