[Impact of elective single embryo transfer criteria on the twin pregnancy rate in a French population]

Abstract

To reduce the twin pregnancy rate and their morbidity, several recommendations have been proposed to practice the "elective single embryo transfer" in a selected population. We decided to apply the criteria that were proposed in five articles from the literature to our population to evaluate the percentage of our population concerned and the impact on our twin pregnancy rate. The result is that these criteria only concern 2,4 to 10,8% of our population with a minor reduction of our twin pregnancy rate with a potential lake of chance concerning the pregnancy rate. We should study others possibilities than the population's criteria to reduce the number of embryo transferred.
