Abstract

Neonatal outcome of in vitro fertilization (IVF) pregnancies has been described by different authors, but several issues have yet to be resolved. The aim of the present study was to evaluate neonates conceived in vitro and to direct special attention to neonatal morbidity and prevalence of minor abnormalities. The information that has been accumulated so far is scant. The first 100 babies conceived in vitro, and subsequently born in our institute, were investigated and compared with the general, spontaneously conceived newborn population. All infants were examined by a senior neonatologist, and the data that were recorded included gestational age at delivery, birth weight, gender, major malformations, minor congenital abnormalities, neonatal mortality, and neonatal morbidity (including asphyxia, jaundice, meconium aspiration, hypoglycemia, and hypocalcemia). The data indicate that the IVF neonates assessed had a higher rate of low birth weight (37%), twinning (30%), and preterm birth (20%) in comparison with the general reference population (p < 0.05). However, no differences were encountered either in the rate of small for gestational age infants or the incidence of major malformations and minor abnormalities between these gro...Continue Reading
