‘She would dream of that till then, tomorrow, of her dream of yester eve.’ –James Joyce
Now, medical professionals have known for a very long time that the vagina is an ideal route for drug delivery. The reason for this is that the vagina is surrounded by an impressive vascular network. Arteries, blood vessels, and lymphatic vessels abound, and—unlike some other routes of drug administration—chemicals that are absorbed through the vaginal walls have an almost direct line to the body’s peripheral circulation system. So it makes infinite sense, argue Gallup and Burch, that like any artificially-derived chemical substance inserted into the vagina via medical pessary, semen might also have certain chemical properties that tweak female biology. (…)
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).
Given these ingredients—and this is just a small sample of the mind-altering “drugs” found in human semen—Gallup and Burch, along with psychologist Steven Platek, now at the University of Liverpool, hypothesized that women having unprotected sex should be less depressed than suitable control participants.
