Motor behaviour in infancy is associated with neurological, cognitive, and behavioural function of children born to parents with reduced fertility.

Aim: To evaluate the associations between motor development in infancy and developmental outcomes at school age.

Method: Participants were 195 children (99 males, 96 females; mean age [SD] 9y 3mo [3mo], range 8y 4mo-10y 11mo) born to couples whose reduced fertility was or was not treated with assisted reproductive technologies. Motor behaviour was assessed at 4, 10, and 18 months with the Infant Motor Profile (IMP).

IVF procedures are not, but subfertility is associated with neurological condition of 9-year-old offspring.

In vitro fertilization (IVF) is not associated with neurological abnormalities in offspring's early childhood. Yet, it is unclear whether this is also true for school age. Neither do we know the role of parental subfertility in offspring's neurological development.
