NEURODEVELOPMENTAL OUTCOMES OF SINGLETON CONCEIVED FROM FRESH AND FROZEN EMBRYO TRANSFER COMPARED WITH NATURALLY CONCEIVED

Overview

This study aimed to: detect difference in neurobehavior, maturity, Apgar score and birth weight of singleton conceived from fresh and frozen embryo transfer and naturally conceived.

The use of ART has increased significantly during the past decades with more than 390000 children born worldwide annually and the total number of ART children now exceeding 7 million (Adamson et al., 2018). ART is associated with an increased risk of perinatal complications, including preterm birth (PTB) and small for gestational age (SGA) (Pandey et al., 2012 and Pinborg et al., 2013). When mothers had been received ovarian stimulation in ART, multiple follicles and corpora lutea are produced, which produce supraphysiologic serum levels of multiple hormones and other factors, including estradiol, progesterone, and vascular endothelial growth factor (VEGF). This non physiological hormonal milieu affects both the endometrium and the embryo, potentially resulting in altered growth of the developing fetus. There was a serious effect of the supraphysiologic hormonal environment on pregnancy outcomes. (Imudia et al., 2012). Neonates born after an IVF/ICSI procedure have an increased risk of various developmental problems, neurological disabilities, impairments or handicap, especially the cerebral palsy (CP) (Strömberg et al., 2002 and Squires and Kaplan, 2007).The increased risk of prematurity and smaller birth weight after an ART procedure required regular periodic screening and careful developmental follow-up of these children. (Boulet et al., 2008). Singleton born after an IVF procedure were more likely to need habilitation treatment and had increased risk of developing neurological problems, especially cerebral palsy (CP), suspicion for a delay in their development. (Strömberg et al., 2002) Children born after an IVF procedure had three times higher presence of CP compared to the children from the general population and the risk of suspicion for a delay in their development was four times higher in children born after an IVF procedure than in the naturally conceived. (Strömberg et al., 2002). There is evidence of associations among the ART procedure and the developmental delay (Hvidtjørn et al., 2009). The lack of early examination of neonates׳s neurobehavior conceived from ICSI/IVF may be led to developmental delay in these neonates. Early detection of neurobehavior deviation is essential for effective control of this potentially debilitating morbidity. As there is no available data about neurobehavior of Egyptian neonates conceived from frozen and fresh embryo transfer so there is an arising need to address this gap of knowledge. Thus, to overcome previous limitation, the current study aimed to evaluate neurobehavior of singletons conceived from fresh and frozen embryo transfer compared with naturally conceived and screening for identify need for early intervention and developmental follow up to prevent worsening and progression of dysfunctions.
