INTRODUCTION

The following guidelines are aimed at providing a consensus view on special topics in urological andrology, which seem to the EAU Infertility Group to be key points in the daily work of urologists dealing with infertility. These topics reflect our literature review and rating, debates of the pros and cons, and final recommendations of our expert group, with special focus on the different national views and clinical practice in European countries.

The group is aware of the fact that infertility in particular has to be discussed as an original interdisciplinary subject, with paternity in a sterile partnership being the primary goal of all clinical work. This understanding implies the cooperation with non-urologists in all aspects of infertility in daily work, and knowledge of other pertinent guidelines, issued by well-accepted authorities such as WHO, the ESHRE Andrology Special Interest Group and the European Academy of Andrology. Accepting these recommendations, our group is convinced that the following guidelines will help European urologists in their interdisciplinary situation to focus on their special skills and knowledge and to understand better the outcome for the patient and the couple.

ANDROLOGICAL INVESTIGATIONS AND SPERMATOLOGY

Ejaculate analysis

Ejaculate analysis has been standardized by the World Health Organization (WHO) and propagated by continuing work and publications in the Laboratory Manual for Human Semen and Sperm-Cervical Mucus Interaction, which is in its fourth edition [1]. The consensus is that modern spermatology has to follow these guidelines without exclusions.
