Impotence – inability to get an erection ( erectile dysfunction ), can be psychogenic or organic.
Arteriogenic[edit | edit source]
Insufficient arterial inflow[edit | edit source]
- Central – arterial occlusion in the aortoiliac region.
- Peripheral - arterial occlusion of the branches of the pelvic arteries or directly of the penile arteries.
- Others – arterial injuries during fractures of the pelvic bones, dysplasia of the deep arteries of the penis.
Treatment[edit | edit source]
- Reconstructive procedures on pelvic arteries (endarterectomy, bypasses ).
- Or penile arteries (epigastric-penile bypass).
- When they fail to implant a penile endoprosthesis
Phlebogenic[edit | edit source]
- Increased venous outflow (insufficient blockage).
- Treatment with ligation or embolization of veins ( v. dorsalis penis , v. penis profunda ).
- Conservative treatment with vasoactive substances (relaxation of the smooth muscle of the supply arteries) – prostaglandins , papaverine, sildenafil (Viagra®) = phosphodiesterase inhibitor.
