摘要
We summarise and comment on the topics discussed by the contributors to this Special Issue. As an introduction, Ann Jequier＇s [ 1 ] generally positive assessment of the new-look manual was tempered with her res- ervations about reference values, on which other chapters dwelt at length. Aspects of laboratory technique were discussed by Charlene Brazil [2], whose offering gives a rare insight into the actual workings of andrology laboratories and highlights the need for greater involvement of laboratory directors （often clinicians） in assessing the quality of data provided.
