I dunno. Assuming no major BO or BB is present, I'm pretty sure smell has little to do with my mating choices. Physical appearance determines the initial attraction (0-1 minute), but then the girl must be mentally stimulating (1 hour - 2 weeks). The last (very) important characteristic is sanity, which can take a while to determine (1 day - 6 months).
I was thinking the same thing as I read the portion of the article that mentioned how a woman's preferences changed during their menstrual cycle. Let's face it, the reason many of us (men) did not want to commit in our 20s and early 30s is because most women we met were just plain nuts.
