Sperm concentration or sperm count means counted sperm cells per milliliter of semen fluid. Total sperm count is found by multiplying sperm concentration value by semen volume mL.  Normal sperm concentration is 15 million sperm cells per mL of semen fluid according to  WHO ( World Health Organisation).

Lower values of sperm concentration than 15 million sperm cells per semen fluid mL is called oligospermia or oligozoospermia. If the semen analysis test is done to evaluate the success of vasectomy operation, sperm concentration value should be zero. If the semen fluid contains no sperm cells this condition is called azoospermia and sperm concentration value is found zero.
