Or: Why Swallowers are Happier
[Editor's Note: Normally, I ignore most of what evolutionary psychology has to say because they are utter pan-adaptationists. Some have even used this proclivity to “rationalize” rape and other seriously fucked up behaviors. However, I couldn’t let this one go... you have my dear friend (genius-cum-hot cougar) Nina, to blame for this shit! For those interested, I had another piece published over at Subversify (click here). I think some here would find it interesting...]
Most of my female readers are probably familiar with the McClintock Effect, also known as the “dormitory effect.” It’s the discovery of the phenomenon wherein the menstrual cycles of women living in close quarters tend to synchronize. This phenomenon has been observed in women living together. It has been found in roommates, close friends, and most strongly between mothers and daughters. It has also been noted in mice, hamsters, and rats. It as suggested that ovulation (process of releasing egg from ovary) is socially regulated and this leads to what is called menstrual synchronicity. In other words, women who live together will have their periods at the same time (there's even a FB page dedicated to this effect)..
It’s a remarkable finding. And this is where my post today starts. The story is connected to a whole chain of events, all of which I will not attempt to duplicate here. If you’re interested in a much more in-depth look at the research I cite in this post, take a look at this article (click here ), or if you’re able, download the cited paper (click here).
A couple of researchers developed an interest in the psychological properties of semen as a result in their exploration of menstrual synchrony. Gordon Gallup and Rebecca Burch, evolutionary psychologists from the State University of New York, had stumbled onto data showing that, unlike heterosexually active women residing together, sexually involved lesbians failed to show evidence of the “McClintock effect.” Since olfactory signals (called pheromones) are known to mediate menstrual synchrony, the authors found this peculiar.
