SCENT OF A WOMAN:

Lo and behold, we are just as sensitive to the scent of the opposite sex as the humble lemming. Humans can discriminate odors in just a single whiff, which at a minimum takes approximately 400 milliseconds. Like male beetles, bees, lizards, lemmings, and a whole suite of other species, men can discern the scent of a woman ready to become pregnant.

They find the smell of sweat from women who are close to ovulation more pleasing and even sexier.

And not just their body odor, men also prefer the voice, the complexion, and basically everything about a woman near ovulation. The thing is, men know women are ovulating because they can smell it, but they don’t know that they know! . . .

Women, the same holds true for us. When we are ovulating we strongly prefer the scent of a male, but not just any male, a more symmetrical male.

Interesting. I had a girlfriend in college that I think I broke up with in part because she smelled wrong. Not bad, just, somehow, wrong.
