A population study from Taiwan found that children conceived by assisted reproductive technology (ART) were slightly more likely to develop asthma, allergic rhinitis or atopic dermatitis compared to children conceived naturally. The study examined the relationship between assisted reproduction and the incidence of these allergic and respiratory diseases in children. The results suggest that assisted reproduction methods may be associated with a modest increase in the risk of these health conditions. The findings are based on an analysis of population-based data and provide information on the potential long-term health consequences of ART. The researchers stress the need for further investigation into the mechanisms that might explain this relationship. Parents considering assisted reproduction should be informed of these findings as part of comprehensive counselling.
