Dear readers: I have come upon a secret treasure, a heretofore-unknown bounty of facts only recently unearthed by a team of evolutionary psychologists. A vital forewarning, though: although the data and information I am about to share oozes with the promise of dramatically improving virtually every aspect of your wellbeing, it can also be abused with tragic—even fatal—consequences. This is so much the case, in fact, that I debated the merits of popularizing this material and do so here only with great circumspection and caution. So please be wise in digesting this semen-related knowledge, and be wiser still in applying it to your own sex lives.

As with the origins of so many great scientific discoveries, this story begins with a serendipitous chain of events. “Our interest in the psychological properties of semen arose as a by-product of an initial interest in menstrual synchrony,” explain co-discoverers Gordon Gallup and Rebecca Burch, evolutionary psychologists from the State University of New York system, in a 2006 chapter about human semen. In particular, Gallup and Burch had stumbled onto a set of intriguing data from the mid-1990s showing that, unlike heterosexually active women residing together, sexually involved lesbians failed to exhibit the well-known “McClintock effect,” in which menstrual cycles in cohabitating women (as well those of females from many other species) are synchronized. Since subtle olfactory cues (called pheromones) are known to mediate menstrual synchrony, write the authors, “This struck us as peculiar…”
