  • Title: A simple multidimensional system for the recording and interpretation of sperm morphology in bulls.
    Author: Nöthling JO, Irons PC.
    Journal: Theriogenology; 2008 Mar 15; 69(5):603-11. PubMed ID: 18242677.
    Abstract:
    This study reports on the development of a data capture sheet for recording the sperm morphology of bulls. The arrangement of the data capture sheet permits the simultaneous recording of the viability and morphology of spermatozoa, and the recording of multiple defects in spermatozoa. Apart from deriving the prevalence of each type of defect, the sheet permits the derivation of the percentages spermatozoa with nuclear defects, defects of the acrosome or tail, respectively, as well as the percentages morphologically normal and normal viable spermatozoa. The arrangement of the data capture sheet further permits the rapid and easy interpretation of the sperm morphology regarding the stage of development, site and extent of malfunction of the reproductive organs, the prognosis for change in the sperm morphology over time and the extent to which defects may be compensated for by normal spermatozoa and the likely fertility of the particular semen sample. The data capture sheet permits a multidimensional, holistic interpretation of the sperm morphology of a bovine semen sample.
