Short answer

These pages explain terms that appear after a semen analysis or an examination. They are not a way to diagnose yourself. Azoospermia and a very low sperm number need clinical assessment. A varicocele is diagnosed by examination, not by a calculator.

Key takeaways

  • Low sperm count is the everyday phrase. Oligospermia is the concentration term.
  • Azoospermia means no sperm were found. It is repeated promptly.
  • Asthenozoospermia means low motility.
  • Varicocele treatment is considered only in specific circumstances.
