Objective To review published results on infertility and subfecundity (time to pregnancy) and to reanalyse existing data in order to elucidate strengths and weaknesses of previously used interview forms and questionnaires, to select models for analysing data, and to estimate differences in infertility between different countries or with respect to differences between groups of couples.To develop a standard questionnaire (or questionnaires) in all European languages after validation and feasibility studies in several European countries.To carry out descriptive studies of infertility and subfecundity in as many European countries as possible in order to assemble internationally comparable data in order to test the questionnaire on a larger scale.Published results and unpublished data sets on infertility and subfecundity were reviewed. The main finding was that concepts and measurement methods were so diverse that there was no sound basis for using existing data for compiling an overview of the distribution of fertility problems in the European countries.Statistical principles of epidemiological analysis of fecundity (time to pregnancy) have been described.Questionnaires have been developed for: a) the study of fecundity (time to pregnancy) and fertility problems in population surveys, and b) the study of fecundity among pregnant women.A number of population surveys and surveys among pregnant women have been conducted.Analysis of survey results is in progress.
