Sperm Pictures – Male Infertility Human Sperm Morphology

Fixed and stained human sperm pictures from our IVF lab

  • Sperm morphology scoring tells us what percent of the sperm are shaped normally
  • Very low morphology scores are associated with male infertility problems
  • Most fertility clinics (including ours) use the “Kruger strict morphology” criteria
  • Using the strict criteria, a relatively low percentage of sperm will be considered to be normal
  • At lease 200 stained sperm are examined with very high magnification to determine if the heads, neck pieces and tails are normal
  • The WHO (World Health Organization) now defines normal morphology as having 4% or more normal forms
  • Due to variations in scoring criteria and the subjective nature of morphology grading, morphology scores can vary significantly between laboratories (on the same sperm specimen)
  • If the sperm count and the motility are normal, a moderately low morphology score might not be indicative of a male fertility problem

Human sperm fixed and stained for morphology test

Several sperm shown on a morphology slide
Special stains and fixatives are used to prepare sperm for morphology evaluation
