With the release of the latest edition of the World Health Organization (WHO) Laboratory Manual for the Examination and Processing of Human Semen (5th edition), Asian Journal of Andrology (AJA) is pleased to present this special issue on "Semen Analysis in 21st Century Medicine" which launches into a sometimes incendiary debate surrounding the recommendations and guidelines for quality control and interpretation set down in the manual. We are honored to invite Prof David J Handelsman and Prof. Trevor G Cooper to be the guest-editors. The purpose of the collection is to discuss some of the behind the scenes controversies, many of which continue, including the origins, utility and specific applications of population reference ranges for semen analysis, problems with modern morphological methodology and the possibility and limitations using semen analysis in population or clinical research studies beyond the original uses for male infertility evaluation. It is our sincere hope that perspectives in this issue will educate readers to approach the new WHO manual with a realistic and critical appreciation of the balance its recommendations represent. In short, we are very excited to present this outstanding collection, and would like to thank two guest-editors and all of our authors for their contributions and support to AJA. We wish the readers a happy and productive New Year and please sit back and enjoy this Special Issue!.... [click here for more]
