A review of the association between in vitro fertilization and children's neurocognitive development

This review investigated the current research on the association between in vitro fertilization and children's neurocognitive development. Twenty studies were analyzed, encompassing over 23,000 children conceived through IVF, and compared to those conceived naturally. The findings on overall cognitive function were mixed, as measured by IQ. Some studies showed no significant differences between IVF and naturally conceived children, while others suggested slight variations. There is emerging evidence that IVF might correlate with specific cognitive domains like language and motor skills, although more research is needed. Several established factors, including maternal age, education level, and birth weight, are associated with children's cognitive development, regardless of conception method. Future research should explore how these factors interact with IVF and investigate a broader range of cognitive domains. Socioeconomic background and parental involvement are essential considerations for understanding a child's developmental trajectory. The inconclusive nature of some findings highlights the need for further research with larger sample sizes, more extended follow-up periods, and robust methodologies. This research has potential implications for parents considering IVF or ICSI, healthcare professionals providing guidance, and future efforts to tailor support systems for children conceived through assisted conception techniques. Open communication about the current state of knowledge and responsible communication of research findings is crucial.
