Researchers from SUNY Albany have authored a study which claims that certain chemicals found in semen can have a positive effect on the physical and mental health of women who frequently engage in unprotected sex.
Semen is known to contain such "mood-altering chemicals" as estrone and oxytocin, which elevate mood; cortisol, which promotes affection; serotonin, which acts as an antidepressant; and melatonin, which induces sleep.
Using data obtained from an anonymous survey of 293 females on campus, Gordon Gallup and Rebecca Burch, working alongside University of Liverpool psychologist Steven Platek, were able to determine that women who engage in oral sex or have unprotected sex on a regular basis were happier than those who practiced safe sex.
To measure the mood of survey participants, Gallup, Burch, and Platek had the women complete the Beck Depression Inventory, which is a standard clinical test used to assess depressive symptoms.
Of all their findings, perhaps the most interesting was the discovery that sexually active women who usually or always used condoms were on par in their unhappiness with women who abstained from sex altogether.
Gallup and Burch also determined that women with a significant amount of "seminal plasma" in their system have improved concentration, and excel over their semen-deficient counterparts in performing cognitive tasks.
