Abstract

INTRODUCTION:
At first, fresh embryo transfers were viewed as superior and produced significantly greater success rates. Nowadays, the process of freezing and thawing embryos has significantly improved. So, the choice between fresh vs. frozen transfer is much more nuanced.
Since the first live birth following the transfer of thawed embryos in 1984, the proportion of frozen embryo transfersin the United Kingdom has increased from 10.1% in 1991 to 41.2% in 2019.
It is known that obstetricoutcomes in singleton ICSI pregnancies are worse than those after spontaneous conceptions.
With regard to maternal complications, some studies had showed that frozen- thawed ET was associated with lower risks of placenta previa and preterm delivery than fresh ET. On the other hand, frozen-thawed ET may contribute to an increased risk of preeclampsia and gestational diabetes mellitus.
Inthis study, wecompared between the obstetrics outcomes of fresh versus frozen embryo transfer.

AIM OF THE WORK:
The aim of this study was to analyze the obstetric outcomes in singleton pregnancies achieved after fresh embryo transfer versus transfer of frozen-thawed embryo, to compare their effects on some major obstetric complications after ICSI cycles that have not been reported in previous studies.
