During the intervening years, the appearance of several guidelines and consensus statements has given stimulus to focused research questions that in turn, have successfully attracted funding of large scale, international, double-blind, randomized controlled trials. The enhanced level of co-operation between colleagues, centers and countries says a lot about the value and ambition of collaboration that exists internationally to improve patient care and our understanding of reproductive science"-- Provided by publisher.
