Abstract: This study explored the application value of s-Flow technology in evaluating female endometrial receptivity during pregnancy. The clinical data of 104 pregnant women who underwent follicle monitoring, underwent transvaginal ultrasonography during the proliferative phase and receptivity phase, and performed color Doppler ultrasound and s-Flow technology to detect blood flow imaging. The endometrial thickness, blood flow parameters, echo type, endometrial-subendometrial blood flow type and other indexes of two different phases were compared. The endometrial thickness and the blood flow parameters of the uterine spiral artery of the pregnant women were significantly different between the two phases (P<0.05). In the proliferative phase, the endometrial is mainly "third-line sign", and it is mainly hyperecho in the receptivity phase. Correlation analysis showed that there was a positive correlation between endometrial echo type and endometrial-subendometrial blood flow type, CDFI(r=0.710,P<0.05), s-Flow(r=0.692,P<0.05). s-Flow technology is better than CDFI in the display of endometrial-subendometrial blood flow, the difference is statistically significant (P<0.05). The transvaginal s-Flow technology can sensitively display the endometrial-subendometrial blood flow, evaluate the endometrial receptivity, and provide an effective reference for women preparing for pregnancy.
