In December 2005 began the first External Quality Assessment Scheme (EQAS) for Andrology Laboratories organized by the School of Pharmacy and Biochemistry (University of Buenos Aires) and the Fundación Bioquímica Argentina. The aim of this study was to inform the response obtained after the enrollment to participate in the first Argentine EQAS, to discuss the results obtained in the first surveys and to compare them with the ones reported by other foreign programs. The evaluated parameters were sperm motility (videotapes), morphology (digital photography) and concentration (SC) (suspensions of spermatozoa). Participants were asked to follow WHO 1999. Nearly 60 laboratories throughout Argentine participated. The Total Allowable Error was 60%, 50%, 15% and 30% for morphology, progressive rapid motility (PRM), progressive motility (PM) and SC, respectively. The results found were similar to those published by the External Quality Program of the ASEBIR-Spain for the "optimum quality specification" on the "State of the art". When the established requirement of quality was "Biological Variability", the Total Allowable Error decreased significantly for morphology and PRM: 28.2% and 29.3% but not for PM and SC. The present data confirms the need for a Scheme. The high Total Error obtained for morphology and progressive rapid motility demamds to standardizing the procedures and establishing analytical goals based on Biological Variability.
