Semen is a thick, cloudy, white substance that contains sperm and other fluids. Semen is released, or ejaculated, from the penis during a man's sexual climax (orgasm).
The amount of semen ejaculated varies from between a few drops to about 1 tsp (4.9 mL) and usually contains between 40 million and 600 million sperm.
