Atherosclerosis of the Internal Pudendal Artery
  The erection of the penis is a phenomenon caused by vascular congestion (the arrival and intense accumulation of blood in the penis). The internal pudendal artery and its branches, the penile arteries, are responsible for distributing this blood. If these arteries are clogged, erection is impossible. Atherosclerosis is a process that slowly narrows then closes these arteries due to an accumulation of fat on their walls. Smoking is a risk factor for developing atherosclerosis in the internal pudendal artery and in the penile arteries of young men who are sexually impotent.

 Risk factors associated with vascular disease from atherosclerosis (such as cardiac infarction) are: smoking, hyperlipemia (increase in cholesterol and fats), hypertension and diabetes mellitus. The same factors are the causes of erectile dysfunction and sexual impotence. This knowledge is important because it can help smokers to quit and this decision could improve or restore erectile function.

 Exposure to environmental tobacco smoke leads to an acute increase in the levels of low density lipoproteins, a risk factor for the development of atherosclerosis. Thus, the repeated exposure to environmental tobacco smoke can lead to premature atherogenesis and atherosclerosis.
