Capalbo et al . previously analyzed the outcome of 215 single euploid blastocyst transfer
cycles, and reported the implantation potential of embryos with different qualities to be similar to the extent that none of the three blastocyst morphology parameters described by the present study were predictive of embryo euploidy.
Farquhar, "Cleavage-stage or blastocyst transfer
: what are the benefits and harms?" Fertility and Sterility, vol.
ameliorates live birth rate compared with cleavage-stage embryos transfer in fresh in vitro fertilization or intracytoplasmic sperm injection cycles: reviews and meta-analysis.
Although a comparison of the incidence of ectopic pregnancy between cleavage stage transfer and blastocyst transfer
has not been the specific subject of any prior study in the literature, information on this issue can be found in a report by Marek et al. In their study, the authors compared the pregnancy rates in their program when they switched from day 3 to day 5 transfer for all patients.
studies may help dispel fears that single blastocyst transfer
results in poor pregnancy rates.
Single blastocyst transfer
, which is widely practiced in Europe, guarantees a reduction in multiple births, the biggest problem facing fertility specialists worldwide.
The potential association between blastocyst transfer
and monozygotic twinning.
* Blastocyst transfer
. Previously, in cases of in-vitro fertilization, embryos were transferred to the mother's uterus two to three days after fertilization.
Yet another procedure, called blastocyst transfer
, recently has been shown to be successful in countering this, Vercollone says.
Two West Midland women, who have each been trying to conceive for more than three years, have both become pregnant using the blastocyst transfer
Live birth of monochorionic triamniotic triplets after in vitro fertilization and blastocyst transfer
: Case report and review of the literature.
Use of the natural cycle and vitrification thawed blastocyst transfer
results in better in-vitro fertilization outcomes.
The speed of growth has declined since then; however, the development of cryopreservation techniques leads to more success of frozen-thawing cycles than fresh ET, so that the overall success of frozen-thawing blastocyst transfer
cycles is more than 50% and in some cases, the use of transfer together with PGS techniques increase the ART success rate up to 80% (3, 1).
Despite numerous studies and generally accepted opinion that the blastocyst transfer
increases the success rate, the published data still show that this hypothesis is not, at least partly, true .
