title: The significance to bull fertility of morphologically abnormal sperm.
abstract: Bull fertility depends partially on the quality of the spermatozoa (i.e., different spermatozoa defects) produced in the ejaculate, emphasizing the importance of the interpretation of the spermeogram results. This article discusses the production of normal and abnormal spermatozoa and the influence that spermatozoa defects may have on bull fertility.
