Abstract
Semen evaluation is an integral part of the assessment of breeding males and semen that has been processed for artificial insemination. The standard examination includes evaluation of volume and spermatozoal concentration, motility, and morphology. Variability in subjective assessment is reduced by attention to detail and use of standardized techniques. Semen evaluation is a very good screening test for identifying potentially subfertile males or ejaculates but does not accurately or consistently predict fertility. Addition of newer techniques such as flow cytometry with fluorescent staining for assessment of spermatozoal compartments, DNA integrity, and computerized evaluation of motility and morphometry provide additional information for research and cases of infertility and are able to improve multivariable model fit, but the goal of accurate prediction of fertility remains elusive.
