Assisted reproductive technologies and children's neurodevelopmental outcomes

Area of Science:

• Reproductive Medicine
• Developmental Pediatrics
• Public Health

Background:

• Early studies linked assisted reproductive technologies (ART) to developmental disabilities in children.
• Concerns were raised regarding potential neurodevelopmental risks associated with ART conception.

Purpose of the Study:

• To re-evaluate the association between ART and developmental disabilities, considering confounding factors.
• To address data gaps and evolving clinical practices in assisted reproduction.

Main Methods:

• Review of evolving evidence and literature on ART and neurodevelopmental outcomes.
• Consideration of confounding variables such as plurality of birth and gestational age.
• Emphasis on population-based cohorts with longitudinal assessments.

Main Results:

• Initial concerns about ART-related developmental risks may have been overstated.
• Plurality of birth and gestational age are significant independent risk factors for neurodevelopmental disabilities.
• Literature remains equivocal for many neurodevelopmental disabilities in relation to ART.

Conclusions:

• Further research is crucial to clarify ART's role in neurodevelopmental outcomes.
• Longitudinal studies are needed to inform clinical and public health guidance.
• Evolving ART techniques necessitate updated understanding of associated risks.
