About This Tool — Important Information
Please read before interpreting your results
This calculator uses WHO 2021 Laboratory Manual (6th Edition) reference values — the globally accepted gold standard for semen analysis interpretation. Our tool analyses your volume, concentration, motility, morphology, and vitality parameters to give you a clear, personalised report. Results are for informational purposes only and should always be reviewed with a qualified fertility specialist.
What This Tool Does
Compares your semen analysis values against WHO 2021 reference ranges and identifies any parameters outside normal limits.
WHO 2021 Standards
Reference values are from the 6th Edition of the WHO Laboratory Manual for Examination and Processing of Human Semen (2021).
