The longer-term health outcomes for children born as a result of IVF treatment. Part IIMental health and development outcomes

Limited data exist with regard to longer-term mental health and psychological functioning of children born from IVF treatment. With the known adverse perinatal outcome for children born from IVF treatment, it would be expected that there is a negative impact upon their mental development. A search strategy restricted to studies relating to the medical condition of children of at least 1 year of age, born from IVF treatment was performed to include case series, data linkage and prospective studies published from 1 January 2000 to 1 April 2012. Limited long-term follow-up data suggest that there is an increase in the incidence of cerebral palsy and neurodevelopmental delay related to the confounders of prematurity and low birthweight. Previous reports of associations with autism and attention-deficit disorder are believed to be related to maternal and obstetric factors. There exists a potential increase in the prevalence of early adulthood clinical depression and binge drinking in the offspring of IVF, with the reassuring data of no changes with respect to cognitive development, school performance, social functioning and behaviour. Whether these potential associations are related to the IVF treatment, the adverse obstetric outcomes associated with IVF treatment, the genetic or subsequent environmental influences on the children is yet to be determined. In general, the longer-term mental and emotional health outcome for children born from IVF treatment is reassuring, and is very similar to that of naturally conceived children; however, further studies are required to explore any association with depression, and its causality in more detail.
