Nov 19, 2010 - Day 14 (Waxing Gibbous, 97% Full) I feel acceptance today. I feel the calm after a stormy sea. Everything seems all right, and I am accepting things as they are. Today I am supposed to ovulate. I wonder if I actually am ovulating, and how many other women are ovulating today. Are women feeling better and more attractive today? Will they over the next couple of days? I wish there was a menstrual cycle index for all the women around the world. Wouldn’t it be nice to know?

Psychologist Geoffrey Miller and his colleagues from the University of New Mexico examined ovulatory cycle effects on top earnings by 5,300 professional lap dancers working in gentlemen's club. His research showed that girls who were not on the pill earned about $335 per 5-hour shift during peak fertility, $260 per shift during the premenstrual phase, and $185 per shift during menstruation. By contrast, girls using contraceptive pills showed no fertility earnings peaks.

In another study named “A Woman's Voice Can Tell You How Fertile She Is,” researchers found a significant increase in voice attractiveness ratings during ovulation phase in naturally cycling women, and no effect for women using contraceptive pills. And according to a previous research, the sound of a person's voice appears to serve as an honest signal of fitness.

So what’s the significance of this information? If we are indeed fitter and more attractive during ovulation, perhaps we should time significant events on our calendars, like job interviews, around ovulation and not during menstruation. This is fascinating! What’s your experience?
