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.
While there is no agreed upon criteria, the most common definition is that premature ejaculation occurs if the man ejaculates within two minutes of penetration [1]; however, a survey by Alfred Kinsey in the 1940s demonstrated that three quarters of men ejaculate within two minutes of penetration in over half of their sexual encounters.
