Evaluating Endometrial Thickness and Vascular Ultrasound Pattern and Pregnancy Outcomes Inintrauterine Insemination Cycle

The current study aims to investigate whether endometrial thickness and pattern, and blood flow in color Doppler of sonography on the day of administration is a predictor of intrauterine insemination (IUI) success. The study was designed as a cross-sectional prospective clinical study with one-hundred women undergoing an IUI cycle. Interventions of the study include endometrial thickness and pattern and color Doppler flow on the day of administration and cycle parameters were compared between pregnant and non-pregnant patients. Main outcome measures are endometrial thickness and patterns and blood flow in color Doppler. The results showed that the overall pregnancy rate was 38%, which mean that endometrial blood flow on the day of administration was significantly greater in cycles, pregnancy achieved, but endometrial thickness and pattern of sonography were found to have no predictive value on endometrial receptivity. In multi-variant analysis, the following variable affected the pregnancy rate: the women's age, duration of infertility, type, number of IUI cycle, the number of ampules to stimulate dominant follicle, sperm count. In our study, this variability was found to have no predictive value on the outcome of IUI but endometrial flow in color Doppler was positively associated pregnancy outcome.
