Attention, Ladies: Semen Is An Antidepressantby Michael Castleman, Psychology Today
<snip>
Semen is best known for what's not absorbed by the vagina, sperm, which swim through it on their way into the fallopian tubes where fertilization takes place. But sperm comprise only about 3 percent of semen. The rest is seminal fluid: mostly water, plus about 50 compounds: sugar (to nourish sperm), immunosuppressants (to keep women's immune systems from destroying sperm), and oddly, two female sex hormones,
and many mood-elevating compounds: endorphins, estrone, prolactin, oxytocin, thyrotrpin-releasing hormone, and serotonin.
