Aims & Objectives:
The aim of this study was to quantify the risk of adverse perinatal outcomes birth defects and pregnancy complications following assisted reproductive technology
Abstract:
BACKGROUND: Increasing use of fertility therapy has elicited concerns regarding adverse effects for expectant mothers and the health of children thus conceived. AIMS: To study the risk of adverse perinatal outcomes, birth defects and pregnancy complications following assisted reproductive technology (ART). METHODS: Questionnaire-based study involving 1,524 children and 1,182 pregnancies conceived following in vitro fertilisation (IVF) in two units. Outcomes were compared with the general population. RESULTS: In the study group versus the general population; multi-foetal gestations, 26 versus 2%; singleton preterm delivery and low birth weight, 8.7 and 6.4 versus 4.3 and 4%, respectively; non-lethal congenital malformation rate, 2.6 versus 2.1%; placenta praevia, 2.8 versus 0.5%. CONCLUSIONS: Multi-foetal gestations remain the principal cause of adverse perinatal outcomes after ART. Singleton ART pregnancies have an increased risk of preterm delivery and low birth weight at term. Non-lethal congenital malformation rates are not increased following ART. Placenta praevia is increased following ART.
