Short answer

These definitions match the way SemenBoost uses each term. They are orientation, not a diagnosis. Where a term has a full page, the definition links to it.

Key takeaways

  • Semen is the fluid. Sperm are the cells.
  • Concentration and total sperm number are different counts.
  • Reference limits are 5th-centile figures, not fertility certificates.

How to use this list

Search for a word, or jump from a report. If your laboratory uses a different abbreviation, compare the unit before the definition. Million per millilitre is concentration. Million per ejaculate is a total.
