Summary
Transmyometrial embryo transfer significantly increases junctional zone (JZ) contractions, potentially impacting IVF success. This finding suggests further research is needed to compare it with difficult transcervical embryo transfer methods.
Area of Science:
- Reproductive Medicine
- In Vitro Fertilization (IVF)
Background:
- Embryo transfer is critical in IVF cycles.
- Transmyometrial embryo transfer (TMT) has potential benefits but its role is unclear.
- Junctional zone (JZ) contractions during transfer negatively affect outcomes.
Purpose of the Study:
- To investigate the effect of TMT on JZ contractions.
Main Methods:
- Ten patients with prior difficult embryo transfers underwent TMT.
- Transvaginal ultrasound scans were recorded before and after the procedure.
- Recordings were analyzed for JZ contractions.
Main Results:
- TMT significantly increased JZ contractions.
Conclusions:
- Increased JZ contractions post-TMT present a theoretical concern.
- Difficult transcervical embryo transfer also increases JZ contractions.
- A large prospective study is recommended to compare TMT and transcervical transfer in challenging cases.
