Some guys seem to exude sex, a trait often attributed to pheromones, the chemical signals that people supposedly emit when they're in the mood. But turns out, scientists have never been able to find evidence of such pheromones in humans.
In an essay published in the journal Nature, scientists say they haven't pinned down so-called "releaser pheromones" in humans, which would trigger sexual desire. They have, however, found evidence of "primer pheromones" related to physical reactions. Here's more:
Scientists have observed what they think are the effects of human primer pheromones, including studies showing that some compound in the extract from a woman's armpit can cause menstrual cycles of nearby women to sync up. And a recent study found that women can smell a guy's sexual intentions. . . . But without any actual chemicals identified as pheromones, scientists can't test effects on humans, so the jury is out as to whether we communicate via pheromones.
OK, first of all: How cool is it that they may have proven that menstrual-cycle syncing actually happens?! I thought that was just a myth. That makes me wonder if the sexual pheromones thing is also a myth or if maybe it's just not proven yet. What do you think?
