The rest is comprised of rich, happy bodily fluids and a dazzling array of nutrients that aid, protect, and comfort the sperm in its long and arduous journey toward the haughty female egg. Semen contains vitamin C, fructose, magnesium, phosphorus, potassium, vitamin B12, zinc, nitrogen, and calcium. The average male jizzwad is said to contain roughly as much protein as an egg white chicken, not human eggs, of course. And all this life-giving nutrition will only set your diet back 20 calories! The mighty pig, however, shoots out nearly eight billion little piggy wrigglers with every foul porcine orgasm. Just as men are always expected to be making money, they are always making sperm, too—roughly 1, every second.
Oh Baby: Scientists Find Protein That Lets Egg and Sperm Hook Up
A Sperm Cell or Spermatozoa
Skip to content. Today a girlfriend and I were discussing the nutritional value of sperm. While performing oral sex, if you swallow, I was told that it is very high in protein. However, I was also informed that it is very high in calories. This may seem like a weird question, but I would like to know what nutritional benefits are involved when "swallowing" and how many approximate calories are in a man's ejaculation? Thank you for your help in this matter. A typical ejaculation fills up about one teaspoon; the actual amount is determined by a man's age younger men usually make more semen , when he last ejaculated, and how long he's aroused before ejaculating, among other factors.

Researchers at the Wellcome Trust Sanger Institute have discovered interacting proteins on the surface of the sperm and the egg essential to begin mammalian life. These proteins, which allow the sperm and egg to recognize one another, offer new paths towards improved fertility treatments and the development of new contraceptives. Fertilization occurs when an egg and a sperm recognize each other and fuse together to form an embryo. The Izumo protein displayed on the sperm that recognizes the egg was identified in by Japanese researchers who named it Izumo, after a Japanese marriage shrine, but its mate on the egg has remained a mystery. That is until now.
