Embryo selection in IVF.
To optimize success rates of IVF, selection of the most viable embryo(s) for transfer has always been essential, as embryos that are cryopreserved are thought to have a reduced chance of implanting after thawing. Recent developments challenge this concept. Evidence is accumulating that all embryos can now be cryopreserved and transferred in subsequent cycles without impairing pregnancy rates or...
متن کاملEarly embryo development is an indicator of implantation potential.
To maximize the chances of pregnancy during assisted reproduction treatment, it is important to be able to identify embryos with high implantation potential. Embryos which divide more quickly following insemination have been shown to produce higher pregnancy and implantation rates than those which divide later. The aim of this study was to compare the developmental potential of early cleaving e...
متن کاملComparison of elective single cleavage-embryo transfer to elective single blastocyst-embryo transfer in human IVF-ET
OBJECTIVE This study was carried out to compare the clinical outcome of elective single cleavage-embryo transfer (eSCET) to that of elective single blastocyst-embryo transfer (eSBET) in human IVF-ET. METHODS This study was a retrospective study which analyzed for 614 women who visited the Daegu Maria Clinic from August 2008 to December 2009. All were under 37 years old and had more than 8 mm ...
متن کاملEmbryo quality in natural versus stimulated IVF cycles.
BACKGROUND The impact of controlled ovarian stimulation (COS) on oocyte and subsequent embryo quality remains controversial. In the present study we have compared embryo quality in natural and stimulated cycles in the same group of patients. METHODS This retrospective study was comprised of patients with a regular menstrual cycle who had IVF after COS using rFSH in a long GnRH agonist protoco...
متن کاملI-38: Chromosome Instability in The Cleavage Stage Embryo
Recently, we demonstrated chromosome instability (CIN) in human cleavage stage embryogenesis following in vitro fertilization (IVF). CIN not necessarily undermines normal human development (i.e. when remaining normal diploid blastomeres develop the embryo proper), however it can spark a spectrum of conditions, including loss of conception, genetic disease and genetic variation development. To s...
