Sperm: morphology assessment

obovis

Synonym(s): Spermatozoa


Introduction

  • The types and prevalence of abnormal spermatozoa give an indication of the likely fertility of the bull and the section of the reproductive tract which is malfunctioning.
  • This is a relatively crude assessment – the female reproductive tract selects for oviduct colonization only a thousand or so of the millions/billions of sperm inseminated.
  • This selection excludes sperm on the basis of very subtle morphological criteria, together with functional and molecular factors in addition to rejecting the defects visible by microscopy.
  • Additional techniques such as flow cytometry with specifically stained spermatozoa may offer further opportunities to identify abnormalities.
