The goal of this observational study is to evaluate the outcomes of twin pregnancies referred to our center, in order to understand whether the use of different guidelines over time, with more systematic follow-up timing, has improved their management by reducing adverse events. All this would provide us with useful information for a better understanding of the effects of twinhood on pregnancy outcomes, so that we have more accurate information in counseling with patients.
