The semen examination is important in helping to determine the breeding potential of the male (or batch) in question. Despite this, there are limitations to its effectiveness, both inherent and iatrogenic. The inherent limitation is that predicted performance is based on obsolete data reflecting previous (up to several months) spermatogenic history. Iatrogenic limitations are imposed by the method(s) used to collect, handle and examine semen, and also by subsequent interpretation of the results. Here, the discussion will focus upon ways to interpret and minimize errors imposed by iatrogenic factors, including real-life examples. Best practices for semen handling and evaluation will be emphasized, including the rationale for current sperm motility and morphology standards. Finally, biomarkers for specific problems will be discussed, including the use of threshold values.
