Obstetric outcomes after transfer of vitrified blastocysts.
BACKGROUND It has been claimed that the risks to the child resulting from vitrification as compared with the slow-freezing technique, may be higher owing to the high concentrations of potentially toxic cryoprotectants. We therefore retrospectively compared the obstetric and neonatal outcomes in a cohort of children born after transfer of vitrified blastocysts, fresh blastocysts and slow-frozen ...
متن کاملInm-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 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 کاملNeonatal outcomes after the transfer of vitrified blastocysts: closed versus open vitrification system
BACKGROUND Increasing evidence indicates that closed vitrification has been successfully used in the cryopreservation of human oocytes and embryos. Little information is available regarding the neonatal outcome of closed blastocysts vitrification. The aim of this study was to evaluate the effectiveness and safety of blastocyst vitrification using a high-security closed vitrification system comp...
متن کاملObstetric and neonatal outcome after single embryo transfer.
BACKGROUND Single embryo transfer (SET) pregnancies practically lack vanishing twins and may be associated with improved neonatal outcome. Our objective was to compare the obstetric and neonatal outcome of SET singletons with the outcome of singletons following double embryo transfer (DET) and spontaneous conception. METHODS A 7-year (1997-2003) cohort of fresh SET (n = 269) and DET (n = 230,...
