The morphology of human pronuclear embryos is positively related to blastocyst development and implantation.
Human embryos are selected for transfer using morphology at the cleaving and blastocyst stages. Zygote morphology has been related to implantation and pregnancy. The aim of this study was to relate pronuclear morphology to blastocyst development. Zygotes were scored according to distribution and size of nucleoli within each nucleus. Zygotes displaying equality between the nuclei had 49.5% blast...
متن کاملRelationship Between Morphology, Euploidy and Implantation Potential of Cleavage and Blastocyst Stage Embryos
AIM The aim of this study was to investigate the relationship between the morphology, euploidy and implantation rate of cleavage stage and blastocyst stage embryos. SETTING Institution-based, tertiary care in-vitro fertilization centre. STUDY DESIGN This study included a retrospective data analysis of 306 embryos: 154 cleavage stage embryos and 152 blastocysts that underwent biopsy on day 3...
متن کاملEvidence of prostaglandin involvement in blastocyst implantation.
Delayed-implantation mice were used to test for local implantation induction effects of prostaglandins E2 and F2 alpha. Evidence of implantation was gathered by microdissection of implantation sites and by scanning electron microscopy. Indomethacin was tested for the ability to interfere with the mechanisms of estrogen-induced, normal implantation. Both prostaglandins appear to have significant...
متن کاملDiverse Roles of Prostaglandins in Blastocyst Implantation
Prostaglandins (PGs), derivatives of arachidonic acid, play an indispensable role in embryo implantation. PGs have been reported to participate in the increase in vascular permeability, stromal decidualization, blastocyst growth and development, leukocyte recruitment, embryo transport, trophoblast invasion, and extracellular matrix remodeling during implantation. Deranged PGs syntheses and acti...
متن کاملBlastocyst gene expression correlates with implantation potential.
OBJECTIVE To investigate the role of the blastocyst in implantation failure. This study examined trophectoderm (TE) gene expression relative to pregnancy outcome. DESIGN Retrospective experimental study. SETTING Nonprofit research foundation. ANIMAL(S) Six-week-old BDF1 female mice. INTERVENTION(S) Hatching blastocysts underwent trophectoderm biopsy before single blastocyst transfer (on...
