EVALUATION OF DOPPLER ULTRASONOGRAPHY AS A MEANS OF MONITORING IN-VITRO FERTILIZATION AND EMBRYO-TRANSFER CYCLES - PRELIMINARY-RESULTS AND FINDINGS

In vitro fertilization imposes an emotional and financial burden on in fertile couples and has a relatively low success rate, but it offers t heir only means of conception. As uteroovarian perfusion varies during the menstrual cycle and may be related to uterine receptivity, we sou ght to identify hemodynamic parameters that would be of use in monitor ing stimulated cycles and in making decisions about the timing of in v itro fertilization. Uteroovarian perfusion patterns in patients underg oing ovulation induction and embryo transfer were compared with normal ly cycling volunteers. Significant changes in ovarian perfusion were s een with suppression and stimulation. Despite manipulation, no differe nce in uterine perfusion was seen between the groups in the late lutea l phase, the crucial time of implantation We conclude that Doppler ult rasonography may be useful in monitoring artificial cycles and in pred icting uterine receptivity.
