So the Dutch have this experimental television show called Proefkonijnen (it translates to "Guinea Pigs"), where stuff like this happens. The U.S., tragically, has no such show.
Watch as show hosts Dennis and Valerio endure the electrode-induced pangs of simulated labor, and then join us in imagining how one might also simulate the pains of cervical dilation, a widening pelvis, or a perineal tear. What's a perineal tear? Ha! We're so glad you asked. Click here for the details. (Fair warning: perineal tears are not for the faint of heart.)
