A new study conducted at the Jagiellonian University in Krakow, Poland has revealed that large-breasted, narrow-waisted women (like Poland's Ines Cudna) have the highest reproductive potential. Voluptuous women have the highest levels of fertility hormones. Those women with a narrow waist and big bust are significantly more fertile than others, say the scientists. Physical characteristics, such as breast size and waist-to-hip ratio, function as important features used by human males to assess female attractiveness. Hell, we could have told the scientists that.
