An average human ejaculate contains about 180 million sperm (66 million/ml), but some ejaculates contain as many as 400 million sperm. Both quantity and quality of the sperm are important determinants of fertility. A man is considered clinically infertile if his sperm concentration falls below 20 million/ml semen.
The average volume of semen produced in a single ejaculation varies from 2 to 5 ml. The semen from a single ejaculation may contain between 40 million and 600 million sperm âdepending both upon the volume of the ejaculate and the length of time since the last ejaculation.
