Ovulating Strippers make more money

They think it might be the scent, or possibly some sort of kinesthetic communication - an extra wiggle in the walk...

I've long suspected ovulating women have more power over men.

In a particularly stimulating study, researchers have found that lap dancers--women who work in strip joints and, for cash, gyrate in the laps of seated men--earn more when they are in the fertile phase of their menstrual cycle. The finding suggests that women subtly signal when they are most fertile, although just how they do it is not clear.

Women, unlike many mammals, don't come into heat or estrus, a state of obvious fertility that attracts potential mates. Common wisdom has it that estrus was lost as humans evolved. The notion is that women evolved "concealed ovulation" along with around-the-month sexual receptivity the better to manipulate males by keeping them in the dark, says Geoffrey Miller, an evolutionary psychologist at the University of New Mexico in Albuquerque. But now Miller and colleagues have found evidence that a woman’s state of fertility may not be so secret after all.

The numbers suggest that men can tell when a woman is most fertile, although the message seems to be conveyed by "subtle behavioral signals" that evade conscious detection, the authors say. They add that the study couldn't identify whether it is scent or other physical changes that cue the men in, but they don't think it's anything obvious such as type of dance moves or "conversational content."

Evolutionary psychologist Karl Grammer of the Ludwig Boltzmann Institute for Urban Ethology in Vienna says the result fits with his findings that it's possible to detect ovulation through the effect of raised levels of estrogens on the way women walk and dance. "It is highly possible that estrogen modulates motion abilities," says Grammer, in which case "it seems to be most likely that body motion--and not pheromones--is the information carrier."
