O-23: Transfer of Blastocysts Derived from Frozen Thawed Cleavage Stage Embryos Improved Ongoing Pregnancy
Background: The aim of our study was to compare the resulting from transfer of embryos that cryopereserved in cleavage stage after thawing and transfer of embryos after thawing and culture in sequentional media until blastocyst formation. Materials and Methods: In this prospective clinical study, we have evaluated 128 cycles in women undergone in vitro fertilization (IVF) or intracytoplasmic sp...
متن کاملMorphological and morphometric study of early-cleavage mice embryos resulting from in vitro fertilization at different cleavage stages after vitrification
The aim of this study was to examine the possible morphological and morphometric changes resulting from vitrification of embryos at the cleavage stage. In this study, 30 mice early-cleavage embryos at different stages of cleavage, resulting from in vitro fertilization (IVF) techniques, were examined before and after vitrification. Digital images were taken from embryos before and after vitrific...
متن کاملTelomere lengths in human oocytes, cleavage stage embryos and blastocysts
Telomeres are repeated sequences that protect the ends of chromosomes and harbour DNA repair proteins. Telomeres shorten during each cell division in the absence of telomerase. When telomere length becomes critically short, cell senescence occurs. Telomere length therefore reflects both cellular ageing and capacity for division. We have measured telomere length in human germinal vesicle (GV) oo...
متن کاملVitrification of human blastocysts with the Hemi-Straw carrier: application of assisted hatching after thawing.
BACKGROUND The present study was undertaken to examine the usefulness of both vitrification and assisted hatching (AH) on blastocysts that originate from embryos showing different qualities during their cleavage stage. METHODS A total of 281 blastocysts were vitrified (93 vitrification-warming cycles) in a mixture of ethylene glycol-dimethylsulphoxide-Ficoll and sucrose using the Hemi-Straw (...
متن کاملCryopreserved human blastocysts after vitrification result in excellent implantation and clinical pregnancy rates.
We conducted a retrospective review of all frozen ETs from May 2002 to October 2007 using our new vitrification technique in order to determine its efficacy. We found high pregnancy (70.5%; 79/112) and implantation (40.6%; 110/271) rates with the use of this new method.
