Summary
Uterine position can change between mock and real embryo transfers. Ultrasound guidance is recommended for embryo transfer if a retroverted uterus is detected during mock procedures.
Area of Science:
- Reproductive Medicine
- In Vitro Fertilization
- Gynecology
Background:
- Uterine position assessment is crucial for successful embryo transfer.
- Variability in uterine position may impact embryo transfer outcomes.
Purpose of the Study:
- To evaluate changes in uterine position between mock and real embryo transfers.
- To determine the incidence of uterine position changes during the embryo transfer process.
Main Methods:
- Retrospective review of 386 embryo transfer cycles.
- Uterine position recorded during mock and real embryo transfers.
- Analysis of positional changes (anteverted vs. retroverted).
Main Results:
- Significant changes in uterine position were observed between mock and real transfers.
- 18% of patients with a retroverted uterus at mock transfer had an anteverted uterus at real transfer (p < 0.0001).
- Only 1.2% of patients with an anteverted uterus at mock transfer had a retroverted uterus at real transfer.
Conclusions:
- Uterine position is dynamic and can change between mock and real embryo transfers.
- Routine ultrasound-guided embryo transfer is advised for patients with a retroverted uterus identified during mock transfer.
- Considering positional changes may optimize embryo transfer success rates.
