Summary
The aim of this study was to elucidate the separate effects of infertility and its treatment on a range of child health and development outcomes measured at age 3 and 5 years in a national cohort study (the Millennium Cohort Study which recruited over 18,000 children). The population was divided into several groups of children: those who resulted from an unplanned pregnancy; those who resulted from a mistimed pregnancy; those who resulted from a 'planned pregnancy with a usual time to conception', those who resulted from a 'prolonged time to conception' and those who were conceived following infertility treatment.
Key findings:
- Children who were conceived following infertility treatment tended to come from socially advantaged backgrounds whereas children conceived following an unplanned pregnancy were more likely to come from disadvantaged backgrounds.
- For most of the outcomes we examined, there were no excess risks among children conceived following infertility treatment, except a slightly higher increase in behavioural problems and some suggestion of an increased risk of asthma.
- Children conceived following an unplanned pregnancy tended to have poorer health and developmental outcomes although most of these effects tended to disappear after adjustment for other factors.
