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.
Sixty-five percent of the semen present in your ejaculate comes from the seminal vesicles. Thirty-five percent comes from the prostate, giving the semen its characteristic smell. Five percent of your ejaculate is made up of other fluids in the body. When you orgasm, you ejaculate between 1 and 5 milliliters of semen. The average is 2 to 3 milliliters (a small teaspoon). To give you an idea of how this compares to the output of other species, an adult wild male boar produces 0.5 liters of semen per ejaculation.
