Over on We Hunted the Mammoth, there’s a discussion of this odd post by one of those Men Going Their Own Way about copulins — which are apparently sex pheromones secreted by the vagina. This was the first I ever heard of them, which gave me a moment’s panic. I am a biology professor, and I do teach human physiology, and here was this phenomenon I’d never encountered before? Worrisome. But only for a moment. There are a lot of details I know nothing about, so maybe this was an opportunity to learn something new.
I’ve got a small collection of physiology and neuroscience texts, so I checked there first. Nope, unheard of term, nowhere in any of their indices.
