The WHO laboratory manual for the examination and processing of human semen

Semen analysis is one important part of the diagnostic procedures in Andrology. It includes macroscopic, microscopic, biochemical, immunological and microbiological parameters. The newest WHO laboratory manual for the examination and processing of human semen was published in 2010 and is the world-wide basis for standardization of semen analysis. The cut-off values of some standard semen parameters have changed dramatically. The lower reference value of normal sperm morphology is now 4% (15% before). Sperm motility is not any longer characterized by WHO categories a, b, c, d, but by progressively motile (PR), non-progressively motile (NP) and immotile spermatozoa (IM). In addition, the lower reference value for progressive motility was reduced from 50% to 32%.

The new WHO laboratory manual supports andrological laboratories to implement their quality assurance programmes and quality control procedures.
