Total motile sperm count, calculated privately.

Multiply semen volume, sperm concentration and the proportion of motile sperm. Choose total or progressive motility so the result matches the figure you meant.

Semen volume (ml)

From the semen analysis report.

Sperm concentration (million/ml)

Not the total sperm number.

Motility (%)

Use the percentage that matches the choice below.

Which motility figure is this?

Total motility (all moving sperm)Progressive motility (forward-moving sperm)

Result

Total motile sperm count = volume (ml) × concentration (million/ml) × (motility ÷ 100).

Enter volume, concentration and a motility percentage.

This is the number of moving sperm in the sample, using the motility figure you chose. It is a calculation, not a fertility result. Some clinics use their own thresholds when they talk about treatment. We don't apply those here, and this number doesn't say whether conception is likely.

Nothing you enter is stored or sent. The explanation is on the total motile sperm count page.
