Jesse Bering unleashes a flood of unexpected uses for and effects of, yes, semen:
In fact, semen has a very complicated chemical profile, containing over 50 different compounds (including hormones, neurotransmitters, endorphins and immunosupressants) each with a special function and occurring in different concentrations within the seminal plasma. Perhaps the most striking of these compounds is the bundle of mood-enhancing chemicals in semen.
There is good in this goo. Such anxiolytic chemicals include, but are by no means limited to, cortisol (known to increase affection), estrone (which elevates mood), prolactin (a natural antidepressant), oxytocin (also elevates mood), thyrotropin-releasing hormone (another antidepressant), melatonin (a sleep-inducing agent) and even serotonin (perhaps the most well-known antidepressant neurotransmitter). ...
For both men and women, heterosexual and homosexual, knowing that the penis is capable of dispensing a sort of natural Prozacwhether obtained vaginally, anally or orallywithout also considering the viral arms race involving sexually transmitted infections, can lead to very tragic decisions indeed and many undocumented high-risk private bedroom “experiments.” But here’s just one reason to put the breaks on such plans: The HIV-virus, which evolved long after these adaptive antidepressant factors, has apparently come to pirate human semen, such that certain protein factors in seminal plasma, particularly a protein called prostatic acid phosphatase , make HIV up to 100,000 folds more potent than it is outside of the plasma.
