View source for Vasculogenous impotence

Impotence - the inability to have an erection (erectile dysfunction), can be psychogenic or organic.

== Arteriogenous impotence ==

=== Insufficient arterial inflow ===

* '''Central''' - arterial occlusion in the aortoiliac region.
* '''Peripheral''' - arterial occlusion of the branches of the pelvic arteries or directly the arteries of the penis.
* '''Other''' - arterial injuries in fractures of the pelvic bones, dysplasia of the deep arteries of the penis.

=== Therapy ===

* Reconstructive procedures on pelvic arteries (endarterectomies, [[Bypass|bypasses]]).
* Or reconstructive procedures on penile arteries (epigastric-penile bypass).
* If they fail, implantation of penile endoprosthesis.

== Phlebogenous impotence ==

* Increased venous outflow (insufficient blockage).
* Treatment by ligation or embolization of veins (v. dorsalis penis, v. penis profunda).
* Conservative treatment with vasoactive agents (relaxation of the smooth muscle of the feeding arteries) - prostaglandins, papaverine, sildenafil (Viagra®) = [[Phosphodiesterase III|phosphodiesterase]] inhibitor.
