Hur mycket protein innehåller Sperma?

Nutritional value
Semen is primarily water, but contains trace amounts of almost every nutrient the human body uses.[citation needed] It has somewhat higher amounts of commonly deficient minerals, such as potassium, magnesium, and selenium.[39] One typical ejaculation contains 150 mg of protein, 11 mg of carbohydrates, 6 mg fat, 3 mg cholesterol, 7% US RDA potassium and 3% US RDA copper and zinc.[40] When metabolized, protein yields 4 kcal/g, carbohydrate also yields 4 kcal/g, and fat yields 9 kcal/g.[41] Hence the food energy in the typical ejaculation is 0.7 kcal (2.9 kJ).
