  *Cytoplasmic droplets % (CD) includes proximal and distal cytoplasmic droplets as well as cytoplamic droplets trapped within a distal midpiece reflex.
  {dagger}DD, distal droplets; U-IFA, ubiquitin immunofluorescence assay.
  {ddagger}N = number of sperm with a retained CD that were U-IFA +/total number of sperm identified with a retained CD.
