Background: The success of in vitro fertilization and embryo transfer (IVF-ET) cycles depends primarily on the quality of the embryo and the receptivity of the uterus. In addition to embryo quality the receptivity of the endometrium plays a role in the implantation process. Uterine receptivity is widely accepted as one of the main limiting factors in IVF outcomes. Endometrial thickness and endometrial pattern have been regarded as indicators for endometrial receptivity.

Objective: To compare the ultra-sonographic endometrial characteristic in relation to blood flow on Doppler between pregnant and non-pregnant groups of FET patients in IVF/ ICSI cycles.

Methods: This cross-sectional study is approved by the Institutional Ethical Committee (IEC) of Hameed Latif Hospital. Our study consists of 200 women who have come for FET cycle. On 18th day of period cycle, endometrial thickness, resistance index was obtained by transvaginal sonography. In the combined analysis, endometrial thickness groups (group 1: <9 mm; group 2: [Formula: see text]9 mm) were subdivided into two endometrial patterns (triple-line and diffused). The women were divided into the [Formula: see text]-HCG positive and [Formula: see text]-HCG negative groups. For statistical analysis chi-square and Fisher’s exact tests was used. Multiple logistic regression analysis and the receiver operating characteristic (ROC) curve analysis were applied to determine the best predictive variables.

Results: The women in [Formula: see text]-HCG positive group were significantly younger as compared to [Formula: see text]-HCG negative group. Endometrial thickness was ¿ 9mm and RI was lower in group 1. A significant association was found between endometrial pattern and pregnancy outcome. (p-value = 0.01. ROC curve revealed that for ultrasound parameters the area under the curve was around 0.5.

Conclusion: Endometrium pattern and thickness and resistive index on Doppler may better predictor for pregnancy; combined endometrial characteristics do not predict outcomes.
