Do you have a history of Kidney Stones? Did you know that researchers have found that there is a 84% chance that your body will naturally pass them after having sex? This beats the standard medical treatment which is only 48% effective. Researchers surmise that sex stimulates the nerve endings in the lower abdomen which relax the ureter muscles and allow the kidney stones to pass. Doctors suggest 3-4 romps per week for two weeks to pass most stones without the need for more invasive medical intervention.
