[QUOTE="MollieB, post: 2206602, member: 519175"] Blood flow is critical to erections. The arteries expand to increase blood flow to the penis. This blood fills two tubes of spongy tissue which causes them to swell. Meanwhile, the veins narrow, and traps the blood and maintains the erection. After ejaculation, the veins expand and the trapped blood flows back to the body and everything returns to normal. (P.S. That is why it is dangerous if an erection DOESN'T go away. If it goes on for any length of time, the blood trapped there becomes deprived of oxygen. Oxygen poor blood will begin to damage tissue. They say one that is lasting longer than four hours is an emergency for that reason). In addition to other causes, things that affect blood flow can affect erections. High cholesterol, Hypertension, Diabetes all are things that can cause erectile dysfunction. High cholesterol leads **** building up on the walls of your arteries which, in turn, narrows them. Once upon a time it was thought that this build up restricted blood flow in the penis which caused erectile dysfunction. Now, experts believe that it has to dysfunction of the inner lining of the blood vessels (endothelium) and smooth muscle. Dysfunction of this lining causes impairs blood flow. Impaired blood flow = things don't work right. (Mayo Clinic) High Blood Pressure can also, over time, damage the lining of your arteries causing the same result. (Mayo Clinic) Diabetes: Theory is that high blood sugars damage nerves and disrupt their ability to send signals. Without good nerve function erections are more difficult to achieve. High blood sugars can also decreases the elasticity of blood vessels and causes them to narrow, impeding blood flow. Again, poor blood flow = difficulty obtaining desired affect. I don't think medicine has a definite definitive answer about the relationship to the three things listed above and ED. These are some of the general thoughts on the matter and, of course, you have other causes out there too that are totally unrelated (like hormonal dysfunction). [/QUOTE]
