Researchers compared 67 children born with the help of IVF and 67 children born without any medical intervention. They compared their mental ability. The researchers didn’t find any differences between the two groups.
At the same time, the researchers asked about the child’s social, communication, and motor skills. They found that the IVF group achieved higher scores in communication and motor skills.
We should caution that these scores were only based on parental interviews.
