Ovulatory cycle effects on tip earnings by lap dancers:
economic evidence for human estrus

"Normally cycling participants earned about US$335 per 5-h shift during estrus, US$260 per shift during the luteal phase, and US$185 per shift during menstruation. By contrast, participants using contraceptive pills showed no estrous earnings peak. These results constitute the first direct economic evidence for the existence and importance of estrus in contemporary human females, in a real-world work setting."

O ponto 2. Background é bastante engraçado de se ler.
