title: Doppler sonographic findings and their correlation with implantation in an in vitro fertilization program.
abstract: In 45 women from an in vitro fertilization (IVF) program, the uterine and ovarian blood flows were investigated by vaginal Doppler sonography. The resistance index was used to evaluate the blood pattern. When comparing the patients who became pregnant after embryo transfer (ET [group I, n = 12]) with those who did not conceive (group II, n = 33), it is evident that in group I the vascular resistance of the uterine arteries is significantly lower on the day of follicular aspiration. No differences could be detected in the ovarian vessels. The data obtained so far suggest that the receptivity of the endometrium is a crucial factor for successful implantation. In the final analysis, this can be appraised not only on the basis of morphological but also of hemodynamic parameters.
