Although controversial at the time of its introduction, assisted reproductive technology (ART) is now seen as a standard instrument in the toolbox at a doctor's disposal to assist infertile patients. However, ART has not been without its challenges, difficulties, and failings. An honest and open discussion of these hurdles, as well as the implications of new research and advances in assisted reproduction, was the motivation for a conference that took place in September 2013 in Florence, Italy, and ultimately this publication. Ten previously published journal articles, five on basic research and five on clinical work, were chosen by a panel of experts to be presented and challenged by peers in the field at this unique two-day meeting. This booklet brings together updates on those papers from the original authors as well as additional perspectives from leaders in the field. A summary of the conference itself is also included.

[Editorial] Research Integrity in China
China's research capacity has grown dramatically in the past decade, an expansion that is reshaping the landscape of global scientific investigation. This rapid growth has not necessarily been accompanied by an equally measured promotion of the cultural norms of the scientific enterprise. Most troubling is a lack of research integrity, which may hinder China's growth in original science, damage the reputation of Chinese academics, and dampen the impact of science developed in China.
