Assisted reproduction linked to intellectual disabilities in children

And one particular technology had the highest risk

Parents who use assisted reproductive technologies (ART) may be more likely to have children with intellectual disabilities than those who conceive without help, an Australian study suggests.

Researchers examined data on 2876 children conceived with ART and 207,751 born without ART in WA from 1994 to 2002.

Children born with the help of ART were 58% more likely to have intellectual disabilities by age eight or older.

Overall, rates of intellectual disability were still low, however.

Among all children born during the study period, the 3551 diagnosed with intellectual disability represented about 17 in every 1000 live births. Among children conceived with ART, the rate was 20 per 1000.

"The vast majority of children conceived using ART are born healthy and will not be diagnosed with an intellectual disability," said lead study author Dr Michele Hansen of the Telethon Kids
