Short answer

Oligospermia (oligozoospermia) means sperm concentration is below the reference limit. With the WHO values NICE uses, that limit is 16 million per ml. It describes the sample. It does not measure whether a particular couple will conceive, and SemenBoost does not split it into mild, moderate and severe grades because those cut-offs are not in the WHO reference table.

Key takeaways

  • The matching plain-language page is low sperm count, but check the units.
  • Severe oligozoospermia is repeated promptly under NICE, as is azoospermia.
  • Grades used by individual clinics are local definitions.
  • Hormone tests and an examination come after repeated abnormal results, not from a website.

The term

Both oligospermia and oligozoospermia appear on reports and in guidelines. They refer to a low concentration of spermatozoa. They are not the word for poor motility (asthenozoospermia) or abnormal shape (teratozoospermia), though more than one finding can be present. A total sperm number below 39 million is a related but separate result.

Why this site does not grade it

You may read that 10 to 15 million per ml is “mild” and that under 5 million is “severe”. Those bands vary by author. Using them here would pretend SemenBoost has a diagnostic scale. If your clinic uses a grade, ask which definition they mean. If the report shows a gross deficiency, NICE’s timing advice is the practical point: do not wait three months for the confirmatory test.

What usually happens next

Confirm the result, examine the testes, and consider FSH, LH and testosterone when a production problem is possible. Genetic tests are a specialist decision in very low counts and azoospermia, guided by AUA/ASRM recommendations, not by a fixed number on this page. Treatment might be expectant, medical, surgical, or assisted reproduction. The right one depends on the cause and on the other partner’s fertility.
