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.
An average man can ejaculate for at-least four to five times within a period of one hour. As the number of time grows, the quantity and quality of sperm ejaculated reduces. With every ejaculation, the quantity reduces and the sperm becomes more and more watery.he first and second ejaculation can have at-least 1.5 to 5 milliliters of sperm. Lag time also known as the recovery time is the amount of time required for a man to become capable of ejaculating again after one ejaculation. The lag time varies in men based on various factors like age.
