Fun Sex Facts – Semen

A man will ejaculate approximately 18 quarts of semen, containing half a trillion sperm, in his lifetime.  I really would have thought it would have added up to more than 18 quarts but damn, half a trillion sperm is a lot!  Even more interesting is that according to the Re/Search Guide to Bodily Fluids (Paul Spinard, 1994), the average man produces about 3.5 ml of semen per ejaculation whose nutritional value is:

  • less than 1 calorie
  • 150 mg. protein
  • 11 mg. carbohydrates
  • 6 mg. fat
  • 3 mg. cholesterol
  • 7% US RDA potassium
  • 3% US RDA copper
  • 3% US RDA zinc
  • 300 million spermatozoa
