To evaluate the B-Mode changes in uterine environment and in endometrial morphology in different phases of menstrual cycle.

Background & Method: The aim of this study is to evaluate the B-Mode changes in uterine environment and in endometrial morphology in different phases of menstrual cycle. Examination techniques- once the transducer is positioned in the vagina; it must be manipulated to obtain the appropriate image. Result: 70% cases showed myometrial blood flow internal to arcuate vessels on gray scale and almost all of them were fertile. Maximum numbers of cases (76%) have endometrial contractions 3 or more per 2 minute and almost all of them are fertile and almost all cases whom having endometrial contractions 2 or less, belongs to infertile group. Conclusion: The advent of color flow imaging has enabled the detection of neovascularization and change in blood flow in endometrium and myometrium. The absent or poor endometrial vascularity in luteal phase is almost always predictive of unfruitful pregnancy outcome while good endometrial vascularity and low resistance and pulsatility index in luteal phase is associated with fruitful pregnancy outcome. So the success of assisted reproduction program is depends on uterine perfusion and its accurate evaluation. [ABSTRACT FROM AUTHOR]
