At the previous meeting of the Working Group on Late Fertility and its Implications that was held in Paris in collaboration with INED-INSERM, the group examined the possible effects of late parenthood on risks of failure to conceive, for pregnancy outcome, and for the foetus and the newborn. A revised version of the papers has been published as a special issue of the journal Epidemiology and Public Health.
