Total sperm count calculator

What is my total sperm count?

Q: Why does volume matter?

Because concentration is per millilitre. 60 million/mL in a 0.8 mL sample is 48 million total; the same concentration in 4 mL is 240 million. Total count is what reaches the destination.

Q: My volume is low. What causes that?

Incomplete collection is the most common and most easily fixed cause. Beyond that, short abstinence, retrograde ejaculation, and obstruction are considered. Tell your lab if any of the sample was lost.

Q: Does a low count mean IVF is the only option?

No. Total count is one parameter among several, and total motile sperm count predicts treatment options better. Plenty of couples with a below-reference count conceive naturally or with IUI. It is a flag to discuss, not a route decision.

The number of sperm in the whole ejaculate, rather than per millilitre. Volume matters — a high concentration in a very small sample is not the same as a high count.

Well within the reference range. Total count is unlikely to be the limiting factor here.

What each result means

Your result is highlighted. Your own clinic's advice always comes first.

Your result<39

Below the WHO 2021 lower reference limit of 39 million per ejaculate. That limit is the 5th centile of men whose partners conceived naturally within a year — it is a reference point, not a pass mark.

Your result39–60

At or above the lower reference limit. Comfortably within the range seen in men with no known fertility problem.

Your result60+

Well within the reference range. Total count is unlikely to be the limiting factor here.

Calculators for what comes next

How this is worked out

Exact calculationArithmetic on the numbers you enter. If your inputs are right, this figure is right.

Total sperm count is semen volume multiplied by concentration, giving the number of sperm in the whole ejaculate. The WHO 2021 lower reference limit is 39 million — the 5th centile of men whose partners conceived naturally within a year.
