IVF babies do not have lower cognitive skills than naturally conceived children

New research shows that between the ages of three and 11, children conceived artificially can be linked with better scores for reading and verbal tests than children conceived naturally. Researchers analysed data of hundreds of UK children who had been born through IVF or ICSI (when the man has a low sperm count), testing the same groups of children every few years up to the age of 11. They found a positive association between artificial conception and cognitive development when a child was between the ages of three and five. The study published in the journal, Human Reproduction , also shows that parents who undergo such treatments are generally older, more educated and have a higher socio-economic status than parents who had naturally conceived children. Artificially conceived babies are more likely to be part of a multiple birth or have low birth weight, however, this study finds their family backgrounds 'override' the possible negative effects to health that could lessen cognitive ability. The findings are significant given previous studies show a mixed picture, with some research suggesting assisted reproductive treatments can harm a child's cognitive abilities. Researchers Professor Melinda Mills and doctoral student Anna Barbuscia, from the University of Oxford's Department of Sociology and Nuffield College, used data from the UK Millennium Cohort Study, a nationally representative group of 18,552 families.
