Cognitive and motor development of 8-year-old children born after ICSI compared to spontaneously conceived children.
BACKGROUND As a continuation of two large-scale , multicentre studies on the development of 5-year-old ICSI children , we present results of the follow-up study undertaken on the cognitive and motor development of 8-year-old ICSI children . METHODS Developmental outcomes of 151 8-year-old singletons born through ICSI after 32 weeks of gestation were compared with those of 153 singletons of the same age born after spontaneous conception ( SC ) . Part of this population was seen in a cohort at the age 5 years . Outcome measures include Wechsler Intelligence Scale for Children-Revised ( WISC-R ) and Movement Assessment Battery for Children ( ABC ) . RESULTS Regarding intellectual functioning , ICSI children tend to obtain significantly higher total ( P < 0.01 ) , verbal ( P < 0.01 ) and performance ( P < 0.05 ) intelligence scores than SC children , nevertheless remaining in similar ranges . These effects are small ( Cohen 's d < 0.50 ) . High maternal educational level stayed in the regression as a factor accounting for some of the variance in total IQ between the groups . In terms of motor development , no significant differences were found between ICSI and SC children regarding overall motor skills , manual , balance and ball skills . CONCLUSION In this follow-up study , ICSI and SC children show a comparable cognitive and motor development until the age of 8 years
