Pmn-19: A Comparison of Neonatal Outcomes following Transfer of Frozen and Fresh Embryo
Background: Currently, frozen embryo transfers contribute an increasing rate of births from assisted reproductive technologies such as in vitro fertilization (IVF). However, very few studies evaluated the neonatal outcomes from frozen embryo transfer. This study aimed to investigate and compare the neonatal outcomes from frozen embryo transfer versus fresh embryo transfers. Materials and Method...
متن کاملComparison of Pregnancy and Neonatal Outcomes in Frozen and Fresh Embryo Transfer in ART Cycles: A Retrospective Cohort Study
Background & aim: In addition to the benefits of frozen embryo transfer (FET), the key question is whether freezing or melting embryos can cause fetal harm and prenatal complications. This study aimed to assess pregnancy and neonatal outcomes after FET and fresh embryo transfer (ET). Methods: This retrospective ...
متن کاملIncidence and zygosity of twin births following transfers using a single fresh or frozen embryo.
STUDY QUESTION Are all twin births following single embryo transfer (SET) monozygotic? SUMMARY ANSWER Between 1 in 10 and in 1 in 5 twins born after SET are the result of a concurrent natural conception. WHAT IS KNOWN ALREADY The twinning rate after SET is higher than following natural conception. Most studies of twins following SET have incorrectly assumed monozygosity or have not been abl...
متن کاملI-5: Cancellation of Fresh Embryo Transfer: A Future Perspective
Controlled ovarian hyperstimulation (COH) affects adversely implantation following in vitro fertilization and embryo transfer. COH with gonadotropins alters endometrial receptivity and luteal function. In addition periovulatory endometrial characteristics in stimulated cycles are considerably different compared with the natural cycles, and periovulatory secretory transformation is consistently ...
متن کاملEndometrial thickness as a predictor of the reproductive outcomes in fresh and frozen embryo transfer cycles
To evaluate the relationship between endometrial thickness during fresh in vitro fertilization (IVF) cycles and the clinical outcomes of subsequent frozen embryo transfer (FET) cycles.FET cycles using at least one morphological good-quality blastocyst conducted between 2012 and 2013 at a university-based reproductive center were reviewed retrospectively. Endometrial ultrasonographic characteris...
