About the Author AbstractPurpose of the Study To study the role of endometrial and subendometrial blood flow measured by 3D power Doppler as predictors of pregnancy in frozen embryo transfer (FET) cycles. Methods A hospital-based prospective study of two hundred and twenty-one (221) women undergoing FET cycles with a triple-line endometrium C7 mm on day 14 endometrial and subendometrial blood flow was assessed using 3D power Doppler, and various indices endometrial volume, subendometrial volume and their vascularisation index (VI), flow index (FI) and vascularisation flow index (VFI) were obtained and compared between the pregnant and the non-pregnant group. Primary outcome was clinical pregnancy. He is a great teacher and mentor for the young aspiring gynecologist throughout the country.

123Results Out of 221 women, 97(43.89 %) became pregnant, while 124 (56.10 %) failed to become pregnant. The endometrial volume was comparable between the two groups. Endometrial VI, FI and VFI were significantly higher in the pregnant as compared to the non-pregnant group. There was a significant difference in subendometrial VI and VFI between the two groups, but FI was similar. Conclusions Endometrial and subendometrial vascularity by 3D power Doppler can be a useful parameter in predicting pregnancy in FET cycles.
