The effect of endometrial thickness and endometrial blood flow on pregnancy outcome in intrauterine insemination cycles.

Objective: To investigate whether endometrial thickness and endometrial blood flow on the day of hCG administration is a predictor of intrauterine insemination (IUI) success.

Method: A cross-sectional prospective clinical study with simple randomized sampling; Patient: 100 women experiencing the IUI cycle; Interventions: a comparison was made between pregnant and non-pregnant patients in terms of the endometrial thickness and pattern as well as the color Doppler flow on the day of hCG administration and also cycle parameters. Main outcome measures: endometrial thickness and patterns as well as the blood flow in color Doppler.
