The findings of this study would correspond to the necessity of data regarding the implementation of blastocyst transfer
in elective SET or double ET.
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.
Although these results represent a selected group of patients, we believe that they should serve as encouragement to patients and providers who are considering single blastocyst transfer
in the older IVF population," Milki and his co-authors noted in the study, which was recently published online in the journal Fertility and Sterility.
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.
There's no reason why we can't use blastocyst transfer
in donor cycles, where already the pregnancy rate is high, and these are embryos from young women," Giudice said.
Use of the natural cycle and vitrification thawed blastocyst transfer
results in better in-vitro fertilization outcomes: cycle regimens of vitrification thawed blastocyst transfer
Perinatal outcome of blastocyst transfer
with vitrification using cryoloop: a 4-year follow-up study.
