By Goral Gandhi (Learn IVF Clinic) - the Transient motion of embryo
transfer-associated anti-bubble was observed. This prospective study was
performed to determine if this anti-bubble movement can predict a successful
outcome. Transabdominal ultrasound-guided embryo transfer was performed in
187 recipients receiving identical hormone replacement therapy.
All embryo transfers were
performed by the first author, using the Sureview embryo transfer catheter, in
30 ml of culture media. The observation was made of the catheter placement in
relation to the endometrial surface and uterine fundus during embryo transfer.
Ultrasound-guided tracking of anti-bubble within the uterine cavity was done
immediately after the piston was depressed at the time of embryo deposition.
The anti-bubble movement was upwards (group A) in 104 embryo transfers and
downwards (group B) in 83 transfers. No movement of embryo-associated air out
of the uterine cavity, either into the cervix or the intramural portion of the fallopian tube, was observed. The clinical pregnancy rate was similar in both
groups: 47.12% in group A versus 45.78% in group B. The total implantation
rate/embryo transferred was 19.34% in group A compared with 20.07% in group B.
The movement of the embryo transfer-associated anti-bubble is unlikely to be a
factor in predicting success in donor egg IVF cycles.
