What is it about?

This study is inspired by a question from a 28-year-old American patient "Do you have any method to differentiate penile venous contributor from psychogenic factor in erectile function" 1998. We resorted to doing a hemodynamic study on seven fresh male cadavers. Simulating penile venous stripping on clinical patients, we closed every emissary vein closest to the outer tunica with 6-0 nylon to establish the corpora cavernosa being free from a venous leak. Interestingly, a rigid erection ensues unexceptionally. Inferentially penile erection-related veins play a pivotal role in penile rigid erection.

Why is it important?

A rigid erection is easily attainable post-venous stripping in cadavers with no extensibility of corporeal sinusoidal wall to express. Implies the correal fibrosis deserves little room for enrolling an impotence contributor.


Given penile venous stripping enhance rigid erection in cadavers, should it work in alive male?.
