Comparison of Congenital Abnormalities of Infants Conceived by Assisted Reproductive Techniques versus Infants with Natural Conception in Tehran

O-26: Comparison of Congenital Malformation of Infants Conceived by Assisted Reproductive Techniques versus Infants with Natural Conception in Tehran

Background: In many countries, 1% to 3% of newborn infants are conceived by Assisted Reproductive Techniques (ART). Despite the success of ART, there is concern about the risk of congenital malformations among these infants. We report our experience to determine whether use of ART is associated with an increase in major congenital malformations or adverse pregnancy outcomes Materials and Method...

Congenital Malformations in Singleton Infants Conceived by Assisted Reproductive Technologies and Singleton Infants by Natural Conception in Tehran, Iran

Objective Multiple pregnancies occur more frequently in assisted reproductive technology (ART) compared to normal conception (NC). It is known that the risk of congenital malformations in a multiple pregnancy are higher than single pregnancy. The aim of this study is to compare congenital malformations in singleton infants conceived by ART to singleton infants conceived naturally. MaterialsAndM...

Congenital anomalies in infants conceived by assisted reproductive techniques.

BACKGROUND Many studies show that congenital defects in infants conceived by assisted reproductive techniques (ART) are more than infants of normal conception (NC). The aim of this study is to determine the frequency of congenital anomalies in ART infants from Royan Institute and to compare congenital anomalies between two ART techniques.  METHODS In a cross-sectional descriptive study, 400 A...
