This study was aimed to investigate whether uterine blood flow on the day of embryo transfer can be a predictor of pregnancy outcome in human IVF. METHODS: Fifty-one patients undergoing IVF program were included in this study. Serum estradiol levels were measured on the day of hCG administration and uterine pulsatility index (PI) and resistance index (RI) was examined for at embryo transfer of day 3. RESULTS: Of 51 cycles, 22 cycles were clinically pregnant (43.1%) and the implantation rate was 14.7%. Uterine PI and RI had a significant inverse correlation with serum estradiol levels (p<0.05). These uterine blood flows were not significantly different between pregnant and nonpregnant groups. The pregnancy rate was slightly higher in patients with PI more than 3.0 compared to those with PI of 3.0 or less, but there was no significant difference. CONCLUSION: These results suggest that uterine PI and RI at the day of embryo transfer could not be a good predictor of pregnancy in IVF treatment. But they had an inverse correlation with serum estradiol levels on the day of hCG administration.
