Inm-5: Outcomes of Human Vitrified Embryos Transfer
The techniques of cryopreservation let embryos which cannot be immediately transferred to the patient be stored for future use. The first successful pregnancy after transfer of cryopreserved human embryos was described in 1983 by Trounson et al. and the first birth after cryopreservation was later reported in 1984 by Zeilmaker et al.). The technique has rapidly been applied in most in-vitro fer...
متن کاملThe Effect of Prolonged Culture of Chromosomally Abnormal Human Embryos on The Rate of Diploid Cells
Background A decrease in aneuploidy rate following a prolonged co-culture of human blastocysts has been reported. As co-culture is not routinely used in assisted reproductive technology, the present study aimed to evaluate the effect of the prolonged single culture on the rate of diploid cells in human embryos with aneuploidies. MaterialsAndMethods In this cohort study, we used fluorescence in ...
متن کاملAbnormal DNA Methylation of Imprinted Loci in Human Preimplantation Embryos.
PURPOSE To evaluate the epigenetic risk linked to assisted reproductive technology (ART) at single-embryo level by analyzing the methylation status of imprinted H19, PEG1, and KvDMR1 in human preimplantation embryos. METHODS A total of 254 human day 3 embryos produced by ART procedures were collected. All embryos were normally fertilized but unsuitable for transfer or freezing due to poor qua...
متن کاملAbnormal mitochondrial structure in human unfertilized oocytes and arrested embryos.
To clarify the relationship between mitochondria and embryo development, we collected human unfertilized oocytes, early embryos, and arrested embryos. Unfertilized oocytes and poor-quality embryos were collected, and the ultrastructure of mitochondria was determined by transmission electron micrography. Four criteria for determining the mitochondrial state were mitochondrial morphology, cristae...
متن کاملEpithelial cadherin distribution in abnormal human pre-implantation embryos.
BACKGROUND E(epithelial)-cadherin is a vital cell adhesion protein that plays a critical role in morphogenesis. Previous studies of E-cadherin distribution in human embryos have produced equivocal results. METHODS Immunocytochemistry in conjunction with laser scanning confocal microscopy was used to detect E-cadherin in 97 human cleavage stage embryos and 35 blastocysts from normal and abnorm...
