Objective: This study aimed to evaluate the three dimension power Doppler indices together with uterine artery Doppler indices during the day of embryo transfer in predicting the outcome of ICSI cycle. Study design: One hundred and three healthy women with singleton pregnancy werprospective cohort study. Patient and methods: One hundred twenty patients were included in the study during ICSI cycles. This work was done at IVF unite  of Dar El Teb hospital, Egypt. All patients included in the work had these criteria; age; 22–35 years, BMI; < 35 kg/m2, oligo- or oligoas- thenospermia. All patients received along agonist protocol of ovarian hyperstimulation and after follicular retrieval; embryos were trans- ferred at the stage of blastocyst. Three D Power Doppler was done at the day of embryo transfer. Quantitative pregnancy tests were done for every patient. The rates of clinical and ongoing pregnancy were estimated. All women were categorized into two categories: with pregnancy and without pregnancy. Results: Thirty-five percent of patients became pregnant. Our study showed non-significant differences in both groups regarding demo- graphic, clinical and laboratory data except for some vascular pa- rameters (endometrial VI, FI, VFI-subendometrial FI- u PI). Our study revealed a significant increase of some vascular parameters (endometrial VI, FI, VFI-subendometrial FI- u PI).and correlated to pregnancy. The endometrial VFI is the most sensitive vascular pa- rameter correlated to pregnancy. Conclusion: 3DPD is a useful non invasive predictor for IVF out- come.
