The European Association of Urology (EAU) consensus group on male infertility consider that male infertility is an interdisciplinary subject in its own right, with paternity in a sterile partnership being the primary clinical objective. This understanding of male infertility implies co-operation with non-urologists in all aspects of infertility in daily work, and knowledge of other pertinent guidelines, issued by well-accepted authorities such as the World Health Organization (WHO), the ESHRE Andrology Special Interest Group [1] and the European Academy of Andrology. Accepting these recommendations, the EAU consensus group on male infertility is convinced that the following guidelines will help European urologists in their interdisciplinary situation to focus on their special skills and knowledge and to achieve a better understanding of the outcome for the male patient and the couple.
