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 volume of a single ejaculate has declined from 3.40 ml to 2.75 ml. This means that men on average are now ejaculating less than half the number of sperm as men did 50 yrs ago. A drop from more than 380 million sperm to about 180 million sperm per ejaculate.Furthermore, the number of motile sperm has also dipped.he volume and content of the ejaculate depend on the length of time between ejaculations. The average volume of semen is 2.75 mililiters(ml) , ranging from 2-6 ml, the higher volumes following periods of abstinence.
