Comparison 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 کاملRetrospective comparative study of the factors affecting birthweights in frozen‐thawed embryo transfer, compared to fresh embryo transfer
Aim Several studies have indicated that the cause of the increased birthweight of frozen-thawed embryos was associated with assisted reproductive technology (ART) procedures, such as cryopreservation. In the present study, the mean birthweight of singletons was compared between the ovulatory and hormone replacement therapy (HRT) cycles in order to investigate the primary factor that leads to hi...
متن کاملSingle Day 2 embryo versus blastocyst-stage transfer: a prospective study integrating fresh and frozen embryo transfers.
BACKGROUND Whether extended culture allowing selection of embryos with high development potential has any advantage over cleavage-stage embryo transfer remains a matter of debate. Among the currently unsolved questions, the cumulative delivery rate resulting from fresh and frozen embryo transfers needs to be taken into account in both strategies. The aim of our study was, therefore, to compare ...
متن کاملPmn-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 کاملPerinatal outcome in fresh versus frozen embryo transfer in ART cycles
BACKGROUND Despite of higher pregnancy rate after frozen embryo transfer (FET) which is accepted by the majority of researches, the safety of this method and its effect on neonatal outcome is still under debate. OBJECTIVE The aim of this study was to evaluate pregnancy and neonatal outcome of FET compare to fresh cycles. MATERIALS AND METHODS In this study,1134 patients using fresh ET and 2...
