Evidence linking conception through assisted reproductive technology (ART) to the subsequent development of atopic diseases has been inconsistent. While some studies have reported an increased risk of asthma among children conceived via ART, others have found no meaningful association. To clarify this relationship, researchers in Taiwan evaluated the risk of atopic diseases in 13,957 children conceived through ART and compared them with 55,828 naturally conceived children.
Over a median follow-up period ranging from 5 to 8 years, children conceived through ART showed a higher risk of developing asthma (adjusted hazard ratio [aHR], 1.13), allergic rhinitis (aHR, 1.15), and atopic dermatitis (aHR, 1.08) than their naturally conceived counterparts. Additionally, among ART-conceived children, those born following fresh embryo transfer had a higher risk of allergic rhinitis compared with…
