Abstract

To compare the rate of ectopic pregnancy (EP) with fresh versus frozen blastocyst transfer in our program during the same time period.Retrospective analysis.University IVF program.Women who achieved a clinical pregnancy after IVF between 1998 and 2005.In our program, cryopreservation is performed at the blastocyst stage. Embryo transfer was performed 1 to 1.5 cm short of the fundus by abdominal ultrasound guidance.The incidence of EP was examined in relation to fresh versus frozen blastocyst transfer.In the frozen blastocyst group, there were 5 EPs out of 180 clinical pregnancies (2.8%), and there were 10 EPs out of 564 clinical pregnancies (1.8%) in the fresh blastocyst group.The rate of EP is not significantly increased after the transfer of frozen thawed blastocysts compared with fresh blastocyst transfer.
