RRM Academy Synopsis

Children conceived by ART have higher birth defect and preterm risk

Children conceived through assisted reproductive technology (ART) are at increased risk of birth defects, a 2016 review reports. Their risk of perinatal complications, such as being small for gestational age, preterm delivery and low birth weight, is also higher. Long-term effects are hard to establish, the authors write, though a number of studies imply that ART may harm blood vessels.

Key Findings

  • Birth defects and perinatal complications, among them low birth weight, preterm delivery and small for gestational age, are more likely in children conceived through ART.
  • The authors state that the characteristics of the parents, the underlying cause of infertility and the ART procedures themselves may contribute to these risks.
  • A number of studies imply that ART may harm the vascular system, and the authors call for follow-up studies of the possible consequences.
  • Studies to date, the authors report, find normal social, emotional, cognitive and motor function in children conceived through ART.
  • Children conceived through ART appear to have no increased risk of childhood cancers, the authors write, despite minor inconsistencies across some studies.

Interpretation

The source is the published abstract of a 2016 review, so only the authors' summary is available here. The abstract reports no study counts, no risk sizes and no search method. The authors name the parents' characteristics, the cause of infertility and the ART procedures themselves as possible contributors to the higher risks. The abstract does not say how much each one adds. The long-term results come from children who were born and followed, so pregnancies that ended earlier fall outside them. The authors judge long-term effects difficult to establish and state that large studies with long-term follow-up are required.

RRM Context

RRM seeks the underlying cause of infertility in both partners and treats it, with natural conception as the goal. The review names that cause as one possible source of the higher risks. IVF and related procedures bypass the cause and leave it in place.

Abstract

Despite their wide and global use, possible short and long-term effects of fertility treatments on children is not well-established. In this review, birth defects and perinatal complications and their relationship with assisted reproductive technology (ART), along with long-term effects of ART on cardiovascular system, metabolism, behavior, cognitive skills, and childhood cancers are discussed. Children conceived through ART are at increased risk for birth defects and perinatal complications such as preterm delivery, low birth weight and small for gestational age. Parental characteristics, underlying infertility etiology and ART procedures themselves may contribute to this. The long-term effects of ART are difficult to establish. Studies so far report that ART children have normal social, emotional, cognitive, and motor functions. Likewise, despite some minor inconsistencies in some studies, they do not seem to be at increased risk for childhood cancers. However, there are a number of studies that imply vascular system may be adversely affected by ART and its possible consequences should be further investigated with follow up studies. Large scale studies with long-term follow up periods are required to determine the effects of ART on conceived children.
