Man Juice: Separating Fat from Friction


You are what you eat. In this case, literally, because sperm contains genetic material. But sperm, despite its payload of Darwinian programmers, is not particularly nutritious, although it does contain protein (including enzymes) and sugars (mainly fructose) secreted into semen by the prostate gland to provide the sperm with the energy to swim. Other good stuff found in semen includes water, vitamin C, citric acid, phosphate, bicarbonates, zinc, and prostaglandins.

Calorie counters will be glad to know that semen isn’t particularly fattening. The average ejaculate, about one teaspoonful, contains between 200 and 300 million sperm. Total calories: about five.
