OBJECTIVE: To obtain a broad knowledge of IVF practice in France and to analyze the main success factors. DESIGN: Prospective study. SETTING: A national IVF registry was established in France in January 1986 and has been in operation since that time. PATIENTS: Data on more than 77,000 assisted reproductive technology (ART) cycles were collected from 97 centers, representing 80% of all French ART activity. INTERVENTIONS: In this registry, a form is completed for every oocyte recovery attempt, containing information about the infertility diagnosis, the attempt itself, and its results. MAIN OUTCOME MEASURE: The main outcome is the clinical pregnancy rate (PR) per ovum pick-up. RESULTS: This report provides data for the period 1986 to 1990 and studies the relationships between pregnancy occurrence and a number of characteristics relating to the couple or the cycle. The mean PR increased from 15.0% in 1986 to 18.7% in 1990. The methodological aspects are discussed, focusing on possible sources of bias and analysis of results. The results obtained in this registry are compared with those from other similar registries worldwide.
