Long-term outcomes for children conceived by assisted reproductive technology

Abstract

Worldwide, more than 10 million children have been born after Assisted Reproduction Technology (ART) and comprised up to 7.9% of children born in Europe and up to 5.1 % of children born in the US in 2018 (1, 2). The short-term outcome for children born after ART is well-known from numerous publications, with higher rates of preterm birth and low birth weight in children born after fresh embryo transfer and higher rates of large for gestational age and high birth weight in children born after frozen embryo transfer compared to children born after spontaneous conception (3, 4). Higher rates of birth defects in children born after ART have also been shown consistently over time (5). Studies on long-term health outcomes after ART are scarcer but suggest an increased risk of altered blood pressure and cardiovascular function in children born after ART. In this review we summarize long-term health outcomes in children born after ART and discuss if the increased health risks are associated with intrinsic maternal or paternal factors related to sub fertility or to the ART treatments per se. Finally, we speculate where the future will bring us with regards to ART treatment strategies and safety of the mother and child.
