Researchers using data from the National Danish Birth Cohort looked at more than 90,000 children born between 1997 and 2003. Participants had been asked whether their pregnancies were planned and how long it had taken them to conceive before a successful pregnancy.
Researchers grouped children by the number of months it took their parents to conceive; parents who conceive quickly are fertile. The groups were zero to two months; three to five months; six to 12 months; and longer than 12 months. Unplanned pregnancies, as well as pregnancies that were the result of IVF, ICSI, and ovulation induction with or without intrauterine insemination were included in the study.
Overall, the time that it took to conceive did not prove to influence the risk of cerebral palsy, even among those who waited 12 months or longer and conceived spontaneously or those who waited the same amount of time and used fertility treatments. The study results showed that:
* Among the more than 90,000 children included in the study, only 165 were diagnosed with cerebral palsy.
* Among the 3,000 children in this group born as a result of IVF/ICSI, only 17 had cerebral palsy, indicating an estimated risk of the disorder as one in 176.
