PD44 - In vitro fertilisation is positively associated with prevalence of asthma in childhood

Background Research on potential perinatal risk factors for asthma, has recently attracted considerable attention. Asthma could be associated with In vitro fertilization (IVF) via epigenetic modification of DNA by IVF drugs/hormones or via a genetic link of asthma with parental subfertility. Nevertheless, evidence of an asthma/IVF correlation is scarce and inconclusive. We therefore opted to explore a potential link, in a cross-sectional population-based study in preadolescent children.
