Abstract:BACKGROUND: The purpose of this study was to determine the consistency in the uterine position between mock and real embryo transfer. METHODS: We reviewed 996 consecutive embryo transfer cycles (585 patients); 74% of patients had an anteverted (AV) uterus and 26% had a retroverted (RV) uterus at mock embryo transfer. All mock and real embryo transfers were performed under abdominal ultrasound guidance. RESULTS: Of 623 fresh embryo transfers in patients with an AV uterus at mock embryo transfer, only 2% became RV, while 55% of 213 embryo transfers in patients with an RV uterus on mock embryo transfer converted to AV at real embryo transfer (P < 0.0001). For frozenthawed embryo transfer, 12% of AV uteri at mock embryo transfer became RV, while 33% of RV uteri became AV (P = 0.01). CONCLUSIONS: Our data suggest that an RV uterus at mock embryo transfer will often change position at real embryo transfer. Misdirecting the embryo transfer catheter can be avoided by accurate knowledge of the uterine position at the time of embryo transfer, which can be more accurately assessed by routine ultrasound guidance. Additionally, patients with an RV uterus at mock embryo transfer should still present with a full bladder for embryo transfer, since a significant number will convert to an AV position.
