May 2010 | AndroExpert has been adapted to the fifth edition of the WHO laboratory manual, published at the beginning of 2010.

Semen analysis is useful in both clinical and research settings for investigating male fertility status as well as monitoring spermatogenesis during and following male fertility regulation and other interventions. This manual provides updated, standardized, evidence-based procedures and recommendations for laboratory managers, scientists and technicians to follow in examining human semen in a clinical or research setting. Detailed protocols for routine, optional and research tests are elaborated.

The fifth edition includes new information on sperm preparation for clinical use or specialized assays and on cryopreservation, an expanded section on quality control in the semen analysis laboratory and evidence-based reference ranges and reference limits for various semen characteristics. The last point is the most striking difference to the fourth edition of 1999. The methods described are intended to improve the quality of semen analysis and the comparability of results from different laboratories.

In addition many new aspects have been introduced rendering the fifth edition a significantly revised and easier to follow handbook providing a step by step procedure for semen analyses in all andrology laboratories.
