In this well-linked news, a team of researchers has reported success at curing erectile dysfunction with shockwaves. When describing how much force is being applied to the penis, they chose a very revealing comparison:

"These are very, very low energy shock waves," Vardi said. Each shockwave applied roughly 100 bar of pressure — some 20 times the air pressure in a bottle of champagne, but less than the pressure exerted by a woman in stiletto heels who weighs 132 lbs. (60 kg).

Apparently medical research is now being performed in full dominatrix gear. Who knew?
