Perinatal 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...

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 ...

Frozen-thawed embryo transfer cycles

In order to reduce the chance of multiple pregnancy during in-vitro fertilisation (IVF)– embryo transfer treatment, there is an increasing trend towards transferring a lower number of embryos. Surplus good-quality embryos are then transferred in frozen-thawed embryo transfer (FET) cycles. The first pregnancy after FET was reported in 1983.1 It has been estimated that in IVF programmes in which ...

Uterine peristalsis before embryo transfer affects the chance of clinical pregnancy in fresh and frozen-thawed embryo transfer cycles.

STUDY QUESTION Does uterine peristalsis influence the chance of clinical pregnancy in an embryo transfer cycle? SUMMARY ANSWER The uterine peristaltic wave frequency before embryo transfer is inversely related to the clinical pregnancy rates in fresh and frozen-thawed embryo transfer cycles. WHAT IS KNOWN ALREADY Uterine peristalsis participates in regulating fluid migration after mock embr...

Endometrial 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...
