I was reading an article on semen because I really wanted to know if it was a good "Protein Shake" for your gf/bf, which ever way you swing. Since most topics on this website is about testosterone, calories and composition, I decided to post something weird but interesting...
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. Contrary to what you've heard, semen is not loaded with calories. Each teaspoon of ejaculate has about 5 - 7 calories and some 200 - 500 million sperm. Since sperm make up only about 1 percent of semen, what accounts for the other 99 percent? Well, its other ingredients include:
* Fructose sugar
* Water
* Ascorbic acid (a.k.a., vitamin C)
* Citric acid
* Enzymes
* Protein
* Phosphate and bicarbonate buffers (bases)
* Zinc
Composition of human semen
Approximately 200- to 500-million spermatozoa (also called sperm or spermatozoans), produced in the testes, are released per ejaculation, amino acids, citrate, enzymes, flavins, fructose (the main energy source of sperm cells, which rely entirely on sugars from the seminal plasma for energy), phosphorylcholine, prostaglandins (involved in suppressing an immune response by the female against the foreign semen), proteins, vitamin C, acid phosphatase, citric acid, fibrinolysin, prostate specific antigen, proteolytic enzymes, zinc (serves to help to stabilize the DNA-containing chromatin in the sperm cells. A zinc deficiency may result in lowered fertility because of increased sperm fragility. Zinc deficiency can also adversely affect spermatogenesis.), galactose, mucus (serve to increase the mobility of sperm cells in the vagina and cervix by creating a less viscous channel for the sperm cells to swim through, and preventing their diffusion out of the semen. Contributes to the cohesive jelly-like texture of semen.), pre-ejaculate, sialic acid.
Can swallowing semen enrich a poor diet? Unless you're gulping gallons of it each day, it's no substitute for real nutritious cuisine.
Psychological aspects
Semen has been proven to act as a strong antidepressant in women so that women physically exposed to semen are less likely to suffer from depression. It is thought that the psychological effects of semen are a result of its complex chemical make-up including several mood-altering hormones (testosterone, oestrogen, follicle-stimulating hormone, luteinizing hormone, prolactin and several different prostaglandins). In a scientific survey of 293 college women it was also found that those who did not use condoms were most likely to initiate sex and to seek out new partners as soon as a relationship ended, suggesting that the chemical dependency to semen creates a "rebound effect". The effect of semen on a male sexual partner (a receiver of semen) is not known.
She appreciates it...
