The Association between Endometrial Parameters in Doppler Sonography and Success Rate of Imlantation in Assisted Reproductive Programs

Introduction: A favorable endometrium is the essential requirement for implantation. The aim of this study was to determine the predictive value of endometrial power Doppler ultrasonographic parameters in predicting the success of implantation in patients undergoing IVF and ICSI cycles. Methods: Seventy three patients aged<38 years with basal serum FSH level<12 , who had not more than two failed attempts of ART cycles and whose uteri were morphologically normal based on ultrasound and had at least two good quality embryos for transfer to their uterus, were studied. Ultrasound evaluation was performed by a single expert on the day of embyo transfer. Then pregnant and nonpregnant groups were compared for ultrasonographic parameters of endometrium by utilization of SPSS software. Results: conception occurred in 28 patients. No significant difference was found between pregnant and nonpregnant groups regarding demographic, hormonal and cycle characteristics. Embryonic parameters were comparable between the two groups. On the other hand none of the ultrasonographic parameters differed significantly in the two groups. Conclusion: Doppler ultrasonographic parameters of endometrium on the day of embryo transfer can not be considered as adequate criteria in predicting the success rate of implantation.
