Long-term outcomes in children conceived with assisted reproductive technologies

Area of Science:

• Reproductive Medicine
• Pediatric Health
• Developmental Biology

Background:

• Assisted reproductive technology (ART) has led to over five million births worldwide, with increasing access annually.
• Investigating ART offspring health outcomes is complex due to confounding factors like prematurity and parental subfertility.
• Existing data suggest generally positive long-term health and psychosocial adjustment in ART-conceived children.

Purpose of the Study:

• To review the current understanding of long-term health, developmental, and behavioral outcomes in children conceived via ART.
• To identify potential risks and benefits associated with various ART methods, including intracytoplasmic sperm injection (ICSI) and cryopreservation.
• To highlight the need for continued research to fully comprehend the long-term implications of ART for offspring health.

Main Methods:

• Systematic review and synthesis of existing literature on ART outcomes.
• Analysis of health, disease, cognitive, developmental, and behavioral data in ART-conceived children.
• Examination of factors influencing outcomes, such as multiplicity, prematurity, low birth weight, and parental characteristics.

Main Results:

• Long-term health outcomes for ART-conceived children are generally favorable.
• Conditions like hypospadias in males conceived via ICSI are noted as potential risks.
• Outcomes for children born after cryopreservation of cleavage stage embryos appear reassuring.
• Many observed long-term conditions may be linked to multiple gestations, preterm birth, low birth weight, or parental subfertility.

Conclusions:

• While ART has enabled millions of births, a complete understanding of long-term health risks and benefits is still developing.
• Further research is crucial for optimizing the health and well-being of children conceived through assisted reproduction.
• Addressing confounding factors is essential for accurate assessment of ART's impact on offspring health.
