Objectives: The aim of this study was to assess the reliability of the mock transfer
during in vitro fertilization processMethod: A case-control study was
conducted on 134 patients included in IVF/ICSI cycles. From the hysterometry
obtained during the mock transfer, the ideal embryo replacement site, i.e.two cm from the uterine fundus has been determined. Results: Significant differences were noted between the area estimated from the mock
transfer and the area where the embryo was deposited during the actual embryo
transfer. In fact, 15.9% of the patients had a difference between four and six
cm, and 32% of the patients returning for a subsequent transfer had at least 2
cm of difference between the embryo deposit zones. This difference was
significant (P < 0.00) Conclusion: More than ultrasound guidance, the challenge with embryo transfer is to be able to
minimize variations in the length of the uterus. This would make it possible to
determine the ideal transfer depot area without multiple manipulations.
