Sperm & semen · In plain English

Sperm count

Usually the total number of sperm in the entire ejaculate. In everyday conversation, sperm count is sometimes used loosely to mean concentration.

Also searched as: total sperm number, total sperm count, low sperm count, oligozoospermia

Why you might see this term

Check which measurement and units your report uses. Total number is calculated from sample volume and concentration.

What to keep in mind

A low count does not mean pregnancy is impossible. No sperm found is a different finding, called azoospermia, and needs specialist assessment.
