Background
I have read the journal’s policy and the authors of this manuscript have the following competing interests: BV has a paid role as a member of the Therapeutic Goods Administration. BV, FA and KS own shares in respective IVF companies (Monash IVF, Virtus Health and Melbourne IVF).‡ These authors are joint senior authors on this work.In vitro fertilisation (IVF) is a common mode of conception. Understanding the long-term implications for these children is important. The aim of this study was to determine the causal effect of IVF conception on primary school-age childhood developmental and educational outcomes, compared with outcomes following spontaneous conception.
