Do in vitro fertilization treatments result in healthy babies?

In Finland, the proportion of children born as a result of in vitro fertilization treatments is annually approximately 3.3%, and the percentage proportion of the population is growing. Their general somatic health status and cognitive development do not differ from spontaneously fertilized children. In vitro fertilization treatments are, however, associated with a slightly elevated risk of preterm delivery, low birth weight and structural abnormalities. The risk of childhood cancer does not appear to be increased in IVF children. The in vitro fertilization process affects the embryonic epigenome, which organizes itself during early embryonic development. These changes may influence the phenotype and health profile of the unborn child. The effect of in vitro fertilization treatments on an individual's long-term health is poorly understood, requiring prospective follow-up studies with sufficiently large datasets. In vitro fertilization treatments are the most effective way to treat infertility, and the treatments are generally safe both for the future mother and the baby being born.
