Sperm/ semen is made up of 65 per cent of fluid from the seminal vesicles, 30 to 35 per cent from the prostate and 5 per cent from the vasa. Semen contains citric acid, free amino acids, fructose, enzymes, phosphorylcholine, prostaglandin, potassium, and zinc. The amount of semen produced varies from a few drops to about 6 ml.
One amount of ejaculate may contain between 40 million to 600 million sperm depending on the volume and the length of time stored before ejaculating. Yet, the quantity of sperm produced will only cover the head of a pin. Samples used for medical study are obtained by requiring the donor to masturbate, or if a sample cannot managed without intercourse, then non-reactive condoms can be used.
