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.

Finally, recall that in addition to antidepressant compounds, semen also contains two female sex hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH spurs egg maturation in ovary. LH is involved in triggering ovulation. Why would semen contain compounds that encourage ovulation? From an evolutionary perspective, this makes perfect sense.
Consider our closest biological relatives, the chimpanzees. Chimp semen contains no FSH or LH, but ovulating females develop a red buttocks, clearly signally reproductive readiness. In contrast, human women have concealed ovulation. Men don't know when women are most fertile. Compared with men whose semen lacked ovulation-triggering hormones, those whose semen contain these hormones would gain a small reproductive advantage. Their semen would encourage ovulation, and their sperm would be more likely to fertilize eggs.

Does semen have antidepressant properties?

Abstract
In a sample of sexually active college females, condom use, as an indirect measure of the presence of semen in the reproductive tract, was related to scores on the Beck Depression Inventory. Not only were females who were having sex without condoms less depressed, but depressive symptoms and suicide attempts among females who used condoms were proportional to the consistency of condom use. For females who did not use condoms, depression scores went up as the amount of time since their last sexual encounter increased. These data are consistent with the possibility that semen may antagonize depressive symptoms and evidence which shows that the vagina absorbs a number of components of semen that can be detected in the bloodstream within a few hours of administration.
