Ovulating Strippers Make Bigger Tips
By JR Minkel and Lisa Stein
Ovulating strippers make bigger tips Strippers looking to shake their
moneymakers most profitably may need only swing to the beat of their
menstrual cycles. In a revealing study, University of New Mexico
researchers (three altruistic guys) recruited 18 subjects (scantily
clad women dancers) to log their work shifts, earnings and menstrual
cycles (phone numbers, too?) on a Web site for two months, or about
5,300 lap dances. The naked truth: participants scored $335 per five-
hour shift while ovulating compared with $260 per shift during the
luteal phase after ovulation and $185 while menstruating. The dancers'
scientifically gyrating pelvises provided the first direct evidence
for human estrus-the equivalent of a baboon's bright red rump-the
group reported in Evolution & Human Behavior. (
