Lap dancers who are taking the contraceptive Pill get fewer tips from the punters, apparently because men prefer more fertile women.
Geoffrey Miller and his team at the University of New Mexico compared the earnings of eighteen naturally cycling lap dancers, from clubs around the New Mexico area, with lap dancers who were taking the contraceptive pill, over a 2 month time span.
Lap dancing is the most intimate form of sex work that is legal in most American cities, and therefore probably as close as researchers can get to studying actual sexual activety.
In their study, the researchers found that during the non-fertile periods of the dancer’s menstrual cycles, both sets of dancers earned similar tips. But when naturally cycling lap dancers entered their fertile period, they earned significantly more in tips than their pill taking co-workers.
Dancers who weren’t on the pill made about $70 an hour from admiring men, during peak fertility, versus about $35 while menstruating and $50 in between. Whilst girls who took birth control averaged about $193 per shift, with a performance peak which was almost a third less than women who were not using the contraceptive. These normally cycling lap dancers earned an average of about $276 per shift (a gain of more than $80 per shift), the study showed.
Dr Miller said:
This is the first direct economic evidence for the existence of estrus in contemporary human females.
It was not made clear whether being at their most fertile made women dance any differently, otherwise ”signal” or ”leak” the fact that they were fertile; or whether men were somehow managing to detect the more fertile women; but the pill produces hormonal signals indicating early pregnancy, and this would not be an enticing target for a would-be suitor.
As a further criticism, this experiment used a rather small sample of dancers; but this aside, it does seem to show some very interesting preliminary evidence.
