Fertility = $$ (Stripper study)

There was a study in the United States which proves that strippers make more money when they are ovulating.

These statistics are average earnings based upon working a 5hr shift:
while on her period = $185
normal part of cycle = $260
during ovulation = $335

While money varies dramatically depending on what part of the country you are in, I do agree with this study. I have personally experienced a huge difference in income depending on what part of my cycle I am in.
