Purpose To assess whether live birth rates (LBR) and maternal/neonatal complications
differed following single fresh and frozen-warmed blastocyst transfer. Methods The present …

BACKGROUND Data show that differences exist in the birthweight of singletons after frozen
embryo transfer (FET) compared with fresh transfer or gamete intra-Fallopian transfer (GIFT) …

Objective To compare gestational age, birth weight (BW), and live birth rates in gestational
carriers (GC) after the transfer of 1 or 2 frozen embryo (s) with or without preimplantation …

Background Multiple pregnancies are one of the major safety concerns of in vitro fertilization
(IVF) due to the increased risk of maternal and neonatal complications. Single embryo …

Background Frozen embryo transfer procedure is becoming more common in assisted
reproduction technology. The effect of this technology is still not yet well studied in …

Objective To examine trends of frozen embryo transfer (FET) proportions and large-for-
gestational-age (LGA) incidence and determine risk factors for LGA infants after FET. Design …

Objective To estimate birth weight differences between patients randomized to fresh or
thawed ET. Design Post hoc analysis of results from two similar randomized trials. Setting …

In recent years, the freeze-all strategy has been widely adopted and applied. However, with
the exception of age, the factors that affect the outcomes of frozen embryo transfer are still …

Purpose To investigate the associations between blastocyst development and the sex ratio
(male: female) among singleton live births resulting from single-blastocyst frozen embryo …

Purpose To evaluate the outcome of frozen-thawed embryo transfer (FET) when freezing
takes place at the pronuclear stage, a retrospective analysis was performed comparing …
