Normal ejaculate contains about 2-3cc of fluid, which is roughly equivalent to a tablespoon. Most of the fluid is protein but there is a small amount of sugar. The caloric count is between 7-15 calories depending on the amount of fluid present.
Sperm only makes up 1% of the fluid which should be anywhere between 200-500 million sperm.
To be specific, ejaculate is made up of: Sperm, water, Vitamin C, Citric Acid, Enzymes, Protein, Phosphate, and Zinc. Sounds nutritious, huh? Well, not really. You would have to ingest about a pint a day for it to provide any nutritional supplementation.
