The initial volume of Biennial Review of Infertility was published in 2009. In the preface to that volume we shared our vision that this series would serve as a forum for evidence-based reviews of cutting-edge topics in the field of infertility, written by experts in the field and accessible and applicable to clinicians and researchers alike. We also began a tradition of highlighting and providing contrasting reviews to emerging and controversial topics. We are very pleased with the response we have had to Biennial Reviews of Infertility, Volume 1, and are excited now to present Volume 2.
