title: [Uterine receptivity and embryo implantation. The use of transvaginal scan and Doppler study in its evaluation in ART].
abstract: Embryo implantation is a multifactorial event. Biochemical factors are implicated in the quality of the endometrium and in its vascularization. The non-invasive vaginal scan studies the endometrial morphology whereas color and power Doppler studies its vascularity. Through an analysis of the literature, we point out the interest of those techniques in ART.
