Sperm morphology and acrosome integrity are also effect tools to estimate semen viability and can also provide more information about the ejaculate in terms of its quality than is possible with just a motility evaluation. Both of these criteria are important to use, along with motility, as a determinant for keeping or discarding ejaculates. Because motile sperm may be morphologically abnormal, poorly motile sperm can fertilize eggs, and sperm without intact acrosomes cannot fertilize eggs, boar studs which do not evaluate all three of these semen quality components likely underestimate the true fertility potential and quality of an ejaculate.
