The findings of this study would correspond to the necessity of data regarding the implementation of
blastocyst transfer in elective SET or double ET.
Blastocyst transfer ameliorates live birth rate compared with cleavage-stage embryos transfer in fresh in vitro fertilization or intracytoplasmic sperm injection cycles: reviews and meta-analysis.
The literature contains 2 additional studies that incidentally report data allowing the computation of the ectopic pregnancy rate with
blastocyst transfer without any information on day 3 transfers.
We feel strongly that single
blastocyst transfer is the way to go," said Marius Meintjes, Ph.
Ectopic pregnancy rates with frozen compared with fresh
blastocyst transfer.
A day 3 transfer was performed when there were 3 or less good quality embryos available on this day; on the other hand a day 5
blastocyst transfer was performed when there were 4 or more good quality embryos on day 3.
David Gardner and his colleagues performed the world's first single
blastocyst transfer trial to improve pregnancy rate and to reduce the risk of multiple gestation (100).
With
blastocyst transfer, it is possible that results could be improved because cleavage-stage embryos are not introduced into the uterine cavity," Dr.
Use of the natural cycle and vitrification thawed
blastocyst transfer results in better in-vitro fertilization outcomes: cycle regimens of vitrification thawed
blastocyst transfer.

blastocyst transfer with vitrification using cryoloop: a 4-year follow-up study.
