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 کاملThe effects of embryo culture media on the birthweight of singletons via fresh or frozen-thawed embryo transfer: a large-scale retrospective study
BACKGROUND Embryo culture media used for IVF treatment might affect fetal growth and thus birthweight of the newborns. METHODS A retrospective study was conducted in South China using data from 2370 singleton neonates born after IVF/ICSI between 2009 and 2012. Two culture media, i.e., either Vitrolife or SAGE were used as embryo culture media during the study period. Neonates' birthweights we...
متن کاملMajor congenital anomalies in children born after frozen embryo transfer: a cohort study 1995-2006.
STUDY QUESTION Is there a different risk for major congenital anomalies (CAs) in children born after frozen-thawed embryo transfer (FET) compared with children born after fresh embryo transfer (ET)? SUMMARY ANSWER Children born after FET have a similar risk of developing major CAs as children born after fresh ET. WHAT IS KNOWN ALREADY The perinatal outcome in children born after FET is as g...
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 کاملFactors affecting obstetric outcome of singletons born after IVF.
BACKGROUND Singletons born after IVF have an adverse perinatal outcome when compared with singletons in the general population. This study investigates maternal characteristics and IVF- treatment-related variables, for a possible influence on obstetric outcomes. METHODS Data from all IVF clinics in Sweden, including all IVF singletons born after fresh treatment cycles and own oocytes during 2...
